Sensaval (Nortriptyline)
Tricyclic Antidepressant (TCA) – Used for Depression
Sensaval contains nortriptyline, a tricyclic antidepressant (TCA) primarily used for the treatment of depression. Nortriptyline works by inhibiting the reuptake of norepinephrine at nerve terminals in the brain, thereby increasing the availability of this neurotransmitter and improving mood regulation. It is the active metabolite of amitriptyline but offers a generally more favourable side effect profile with less sedation and fewer anticholinergic effects. Sensaval is manufactured by H. Lundbeck A/S and is available as 25 mg film-coated tablets requiring a prescription.
Quick Facts: Sensaval
Key Takeaways
- Sensaval (nortriptyline) is a tricyclic antidepressant primarily used for treating depression, with therapeutic effects typically emerging after 2–4 weeks of continuous treatment.
- The recommended adult starting dose is 25 mg three times daily, which may be gradually increased to a maximum of 150 mg per day under medical supervision.
- It must never be combined with MAO inhibitors—at least a 14-day gap is required between these drug classes to prevent potentially fatal serotonin syndrome.
- Common side effects include dry mouth, sweating, tremor, constipation, and palpitations, most of which tend to diminish over time as the body adjusts.
- Special caution is needed in patients with heart disease, epilepsy, glaucoma, or enlarged prostate, and in young adults under 25 due to increased risk of suicidal thoughts during early treatment.
What Is Sensaval and What Is It Used For?
Sensaval belongs to the group of medications known as tricyclic antidepressants (TCAs), one of the oldest and most extensively studied classes of antidepressant drugs. The active ingredient, nortriptyline, primarily works by blocking the reuptake (reabsorption) of norepinephrine (noradrenaline) at the presynaptic neuronal membrane. By preventing this neurotransmitter from being reabsorbed back into nerve cells, nortriptyline increases the concentration of norepinephrine in the synaptic cleft—the gap between nerve cells where chemical signalling takes place. This enhanced noradrenergic transmission is believed to be the primary mechanism underlying its antidepressant effect.
Nortriptyline is pharmacologically unique among the tricyclic antidepressants because it is the most selective norepinephrine reuptake inhibitor within the TCA class. While most other TCAs (such as amitriptyline, imipramine, and clomipramine) have significant effects on both serotonin and norepinephrine reuptake, nortriptyline preferentially targets the norepinephrine transporter. This selectivity gives nortriptyline a somewhat different pharmacological profile compared to other TCAs, resulting in generally less sedation, less weight gain, and fewer anticholinergic side effects. Interestingly, nortriptyline is itself the active metabolite of amitriptyline—meaning that when a patient takes amitriptyline, their body converts a substantial portion of it into nortriptyline through hepatic metabolism.
The primary approved indication for Sensaval is the treatment of major depressive disorder (MDD). The landmark Cipriani et al. (2018) network meta-analysis published in The Lancet, which systematically compared 21 antidepressant medications, confirmed that nortriptyline is an effective antidepressant with a therapeutic profile comparable to other TCAs and newer antidepressant classes. While SSRIs have largely replaced TCAs as first-line treatments for depression due to their more favourable side effect profiles, nortriptyline remains an important therapeutic option, particularly for patients who have not responded adequately to SSRIs or SNRIs, or who cannot tolerate them.
Beyond its approved indication for depression, nortriptyline is also widely prescribed off-label for several other conditions, supported by substantial clinical evidence:
- Neuropathic Pain: Nortriptyline is recommended by NICE and the International Association for the Study of Pain (IASP) as a first-line treatment for neuropathic pain conditions such as diabetic neuropathy, postherpetic neuralgia, and other forms of nerve pain. A landmark comparative study by Watson et al. (1998) demonstrated that nortriptyline was equally effective as amitriptyline for postherpetic neuralgia but with significantly fewer side effects.
- Migraine Prevention: Tricyclic antidepressants, including nortriptyline, are well-established prophylactic agents for migraine, recognized by the American Academy of Neurology and the European Headache Federation.
- Chronic Tension-Type Headaches: Regular low-dose nortriptyline can reduce the frequency and severity of chronic tension headaches.
- Smoking Cessation: Some clinical evidence supports the use of nortriptyline as an aid in smoking cessation programmes, although it is not a first-line treatment for this indication.
It is essential to understand that Sensaval does not provide immediate relief from depressive symptoms. Like all antidepressant medications, it typically takes 2 to 4 weeks of continuous treatment before noticeable clinical improvement begins to occur. Full therapeutic benefits may not be apparent until 6 to 8 weeks of treatment. It is critically important to continue taking Sensaval as prescribed even during this initial period when the medication appears to have little effect, as premature discontinuation can prevent the drug from reaching its full therapeutic potential.
Sensaval is available as white, round, biconvex, film-coated tablets containing nortriptyline hydrochloride equivalent to 25 mg of nortriptyline. Each tablet is marked with “NO” on one side and measures 6 mm in diameter. It is manufactured by H. Lundbeck A/S, a Danish pharmaceutical company specialising in treatments for neurological and psychiatric disorders. Sensaval is available in packs of 100 tablets and requires a prescription from a licensed healthcare provider.
What Should You Know Before Taking Sensaval?
Before starting treatment with Sensaval, it is essential that your healthcare provider has a thorough understanding of your complete medical history, all medications you are currently taking (including over-the-counter products and herbal supplements), and any pre-existing health conditions. Nortriptyline, while generally better tolerated than some other TCAs, still has a broad pharmacological profile that means it interacts with multiple body systems. The following sections provide detailed information on contraindications, warnings, and special precautions that apply to Sensaval use.
Contraindications
Sensaval must not be taken in the following circumstances:
- You are allergic to nortriptyline or any of the other ingredients listed in the “What Does Sensaval Contain?” section
- You have recently had a heart attack (myocardial infarction)
- You have been treated with an MAO inhibitor (monoamine oxidase inhibitor) within the last 14 days
The combination of nortriptyline with MAO inhibitors is one of the most dangerous drug interactions in clinical medicine. When these two drug classes are taken together or in close succession, the result can be serotonin syndrome—a potentially life-threatening condition characterised by involuntary muscle jerking, agitation, hallucinations, coma, excessive sweating, tremor, exaggerated reflexes, muscle rigidity, and dangerously elevated body temperature. A minimum 14-day washout period must be observed when switching between nortriptyline and any MAO inhibitor.
Warnings and Precautions
Several important warnings apply to treatment with Sensaval. You should discuss all of the following with your doctor before starting this medication:
Patients with depression sometimes have thoughts of self-harm or suicide. These thoughts may actually increase when antidepressant treatment is first started, because it takes approximately 2 weeks or longer for the medication to begin working. This risk is particularly elevated in young adults under 25 years of age. Contact your doctor immediately or seek emergency medical care if you experience thoughts of self-harm or suicide. It may be helpful to tell a family member or close friend about your condition, and to ask them to read this information and alert you if they notice changes in your behaviour or mood.
Tell your doctor if you have, or have ever had, any of the following conditions:
- Epilepsy or a history of seizures – nortriptyline can lower the seizure threshold
- Difficulty urinating or an enlarged prostate – anticholinergic effects can worsen urinary retention
- Overactive thyroid gland (hyperthyroidism) – increased sensitivity to cardiovascular side effects
- Liver disease – nortriptyline is extensively metabolised in the liver; dose adjustment may be required
- Heart disease, including heart failure, arrhythmias, or a condition called Brugada syndrome – nortriptyline can affect heart rhythm and conduction
- Schizophrenia – antidepressants can potentially worsen psychotic symptoms
- Bipolar disorder (manic-depressive illness) – Sensaval may trigger a switch into a manic phase, characterised by unusual and rapidly shifting thoughts, unjustified happiness, and excessive physical activity
Sensaval can cause dry mouth (xerostomia), which significantly increases the risk of tooth decay and dental caries. It is therefore particularly important to maintain excellent oral hygiene, including regular brushing with fluoride toothpaste, while taking this medication. Consider informing your dentist that you are taking Sensaval.
Contact your doctor promptly if you develop any of the following during treatment:
- Signs of infection with fever and severely impaired general condition, or fever with local symptoms such as sore throat, mouth pain, or urinary difficulties – blood tests should be performed to exclude a deficiency of white blood cells (agranulocytosis)
- Blurred vision and eye pain – this may indicate glaucoma (increased pressure in the eye) and requires immediate ophthalmological assessment
- Signs of a manic episode – including unusual and rapidly changing thoughts, unfounded euphoria, and excessive physical activity
Children and Adolescents
Sensaval should not be given to children and adolescents under 18 years of age for the treatment of depression, as safety and efficacy have not been established in this age group. Studies with other antidepressant medications have identified risks of suicidal behaviour, suicidal thoughts, and hostility in patients under 18. This risk may also apply to nortriptyline. However, in exceptional circumstances, a doctor may prescribe Sensaval to a patient under 18 if the clinical benefit is judged to outweigh the risks. If you are under 18 and have been prescribed this medication, discuss the reasons with your doctor.
The long-term effects of nortriptyline on growth, maturation, intellectual function, and behavioural development have not been established in children and adolescents under 18 years of age.
Pregnancy and Breastfeeding
If you are pregnant, think you may be pregnant, or are planning to have a baby, consult your doctor before taking Sensaval. There is a risk that nortriptyline may affect the developing foetus. The decision to use Sensaval during pregnancy should always be made in careful consultation with your healthcare provider, weighing the potential risks against the benefits of treating the underlying condition.
The active substance in Sensaval passes into breast milk, and it is possible that a breastfed infant could be affected. You should therefore not use Sensaval while breastfeeding unless specifically directed to do so by your doctor, who will carefully weigh the benefit of treatment for you against the potential risk to your child.
Driving and Operating Machinery
Sensaval can impair your reaction time and ability to concentrate, particularly during the initial period of treatment or after dose changes. You should exercise caution when driving motor vehicles or operating machinery that requires alertness. You are personally responsible for assessing whether you are in a fit condition to drive or perform work requiring full attention. The medication’s effects and side effects are described throughout this guide—consider all of this information carefully when making such assessments, and discuss any concerns with your doctor or pharmacist.
Alcohol
Alcohol should be avoided during treatment with Sensaval. Both nortriptyline and alcohol are central nervous system depressants, and their combined use can significantly enhance the negative effects of alcohol, including increased sedation, drowsiness, impaired coordination, and slowed reaction times. This combination also increases the risk of falls, accidents, and potentially dangerous respiratory depression.
Lactose Content
Sensaval tablets contain lactose monohydrate as an inactive ingredient. If your doctor has told you that you have an intolerance to certain sugars, contact your doctor before taking this medicine.
How Does Sensaval Interact with Other Drugs?
Nortriptyline interacts with a wide range of medications due to its pharmacological profile, which includes norepinephrine reuptake inhibition, anticholinergic activity, and antihistaminergic effects. Some interactions can be serious or life-threatening, while others may require dose adjustments or increased monitoring. It is critically important that your healthcare provider and pharmacist are aware of all medications you are taking, including prescription drugs, over-the-counter medications, vitamins, nutritional supplements, and herbal products. If you are scheduled for surgery or a dental procedure requiring anaesthesia (general or local), you must inform the surgeon, dentist, or anaesthetist that you are taking Sensaval.
Major Interactions (Avoid Combination)
| Interacting Drug | Risk | Recommendation |
|---|---|---|
| MAO inhibitors | Serotonin syndrome – potentially fatal | 14-day washout required between drugs |
| Buprenorphine | Serotonin syndrome – potentially life-threatening | Avoid combination; use alternative analgesic |
| Adrenaline (epinephrine) | Potentiated cardiovascular effects; hypertensive crisis | Use with extreme caution; inform anaesthetist |
| Dopamine | Potentiated cardiovascular effects | Avoid combination in non-emergency settings |
Moderate Interactions (Use with Caution)
| Interacting Drug | Effect | Action |
|---|---|---|
| Cimetidine | Increased nortriptyline plasma levels | Consider alternative acid suppressant (e.g. omeprazole) |
| Clonidine | Reduced antihypertensive effect of clonidine | Monitor blood pressure; may need alternative antihypertensive |
| SSRIs (fluoxetine, paroxetine, sertraline) | Increased nortriptyline levels via CYP2D6 inhibition | Dose reduction may be needed; monitor for toxicity |
| Venlafaxine | Increased nortriptyline levels; additive serotonergic effects | Monitor closely; adjust dose if needed |
| Opioids (codeine, tramadol) | Increased sedation; tramadol also carries serotonin syndrome risk | Use alternative analgesics if possible |
| NSAIDs (ibuprofen, diclofenac) | Increased risk of gastrointestinal bleeding | Use with caution; consider gastroprotection |
| Anticoagulants (aspirin, warfarin) | Increased bleeding risk | Monitor INR if on warfarin; observe for bleeding signs |
| Carbamazepine, phenobarbital | Reduced nortriptyline levels via hepatic enzyme induction | Higher doses may be needed; monitor blood levels |
| Bupropion | Increased nortriptyline levels via CYP2D6 inhibition | Monitor for increased side effects; dose adjustment |
| Fluconazole, terbinafine | Increased nortriptyline levels via CYP inhibition | Monitor for toxicity; dose adjustment may be needed |
| Quinidine, propafenone, flecainide | Additive cardiac effects; increased nortriptyline levels | ECG monitoring if combination unavoidable |
| Antipsychotics (haloperidol, risperidone, chlorpromazine) | Increased nortriptyline levels; additive anticholinergic effects | Monitor for excessive sedation and anticholinergic toxicity |
| Antihistamines (promethazine) | Additive sedation and anticholinergic effects | Avoid combination if possible; use non-sedating alternatives |
| Valproic acid | Increased nortriptyline levels | Monitor for increased side effects; dose adjustment |
If you are scheduled for any surgery (including dental procedures) and will receive general or local anaesthesia, you must tell your surgeon, dentist, or anaesthetist that you are taking Sensaval. The interaction between nortriptyline and anaesthetic agents, particularly adrenaline-containing local anaesthetics, can cause significant cardiovascular complications including dangerous increases in blood pressure and heart rhythm disturbances.
What Is the Correct Dosage of Sensaval?
Sensaval dosing is individualised based on the condition being treated, the patient’s age, overall health status, response to treatment, and tolerance of side effects. The general principle is to begin with a low dose and increase gradually over several weeks. This “start low, go slow” approach helps to minimise side effects while allowing the body to adjust to the medication. Sensaval tablets should be swallowed whole with water and can be taken with or without food.
Adults
Adult Depression Dosing
- Starting dose: 25 mg three times daily (75 mg total per day)
- Dose escalation: Your doctor may gradually increase the dose in increments
- Maximum dose: 50 mg three times daily (150 mg total per day)
- Duration: Treatment length is individual and typically at least 6 months; determined by your doctor
It may take several weeks before you notice improvement. Continue taking the medication as prescribed even if you do not feel an immediate effect. The underlying condition may persist for a long time, and stopping treatment too early can cause symptoms to return. Never change your dose without first discussing it with your doctor.
Elderly Patients
Elderly Dosing
- Starting dose: 25 mg once daily
- Dose escalation: Gradual increases as tolerated
- Maximum dose: 100–150 mg daily (total)
Elderly patients require lower starting doses and slower dose escalation due to increased sensitivity to the cardiovascular and anticholinergic effects of nortriptyline. Age-related changes in liver metabolism and kidney function can also affect how the body processes the drug, leading to higher plasma levels at standard adult doses.
Children and Adolescents
Paediatric Use
Sensaval must not be given to children and adolescents under 18 years of age for the treatment of depression, as safety and efficacy have not been established for this age group. Studies with other antidepressants have identified an increased risk of suicidal behaviour, suicidal thoughts, and hostility in patients under 18. This risk may also apply to nortriptyline.
Duration of Treatment
As with all antidepressant medications, it may take several weeks before you begin to feel better. This delay is normal and reflects the time required for the medication to produce meaningful neurobiological changes. Treatment duration is determined by your doctor and is usually at least 6 months for a first episode of depression. Continue taking the tablets for as long as your doctor recommends. Do not stop treatment simply because you feel better—the underlying condition may persist, and premature discontinuation frequently leads to relapse.
Missed Dose
If you forget to take a dose of Sensaval, take your next scheduled dose at the usual time. Do not take a double dose to make up for a missed one. If you regularly forget doses, consider setting a daily reminder or alarm to help maintain consistent dosing.
Overdose
If you or someone else has taken too much Sensaval, or if a child has accidentally swallowed the medication, contact emergency services or your local poison control centre immediately, even if there are no symptoms yet. Tricyclic antidepressant overdose can be life-threatening and symptoms may develop rapidly. Bring the medication packaging with you when seeking medical attention.
Overdose symptoms may include dilated pupils, rapid or irregular heartbeat, seizures, agitation, confusion, hallucinations, low blood pressure, breathing difficulties, drowsiness progressing to coma, and in severe cases, cardiac arrest. Children are particularly sensitive to the toxic effects of tricyclic antidepressants, making safe storage critically important.
Stopping Treatment
Your doctor will determine when and how to taper your dose of Sensaval to avoid unpleasant withdrawal symptoms that can occur with abrupt discontinuation. Withdrawal symptoms may include headache, malaise, drowsiness, irritability, nausea, and sleep disturbances. These symptoms are generally not dangerous but can be uncomfortable. Never stop taking Sensaval without consulting your doctor first, as your doctor will create a gradual dose-reduction schedule tailored to your situation.
What Are the Side Effects of Sensaval?
Like all medications, Sensaval can cause side effects, although not everyone experiences them. Many of the most common side effects are related to nortriptyline’s anticholinergic properties (blocking acetylcholine receptors) and are generally most pronounced at the beginning of treatment. Starting at a low dose and increasing gradually can help minimise these effects. Most side effects tend to improve as your body adjusts to the medication over the first few weeks of treatment.

Frequently Asked Questions About Sensaval
For the treatment of depression, Sensaval typically takes 2 to 4 weeks before you begin to notice any improvement in your mood and depressive symptoms. Full therapeutic effects may not be apparent until 6 to 8 weeks of continuous treatment. It is crucial to continue taking the medication as prescribed during this period, even if you do not feel an immediate benefit. The sedative effect, which can help with sleep disturbances associated with depression, often occurs from the first few doses. If you have not experienced any improvement after 6 to 8 weeks, your doctor may reassess your treatment plan.
Nortriptyline (sold as Sensaval) is the active metabolite of amitriptyline—meaning that when you take amitriptyline, your body converts a significant portion of it into nortriptyline. However, nortriptyline differs from amitriptyline in several clinically important ways. Nortriptyline is more selective for norepinephrine reuptake inhibition, while amitriptyline has broader effects on both serotonin and norepinephrine. As a result, nortriptyline generally causes less sedation, less weight gain, and fewer anticholinergic side effects (such as dry mouth and constipation) compared to amitriptyline. A landmark study by Watson et al. (1998) demonstrated that nortriptyline was equally effective as amitriptyline for nerve pain but with significantly fewer side effects.
Sensaval can impair reaction time and concentration, particularly during the early phase of treatment or after dose changes. While nortriptyline generally causes less sedation than amitriptyline, individual susceptibility varies. You should not drive or operate heavy machinery until you know how Sensaval affects you personally. If you experience drowsiness, dizziness, or blurred vision, you should avoid driving. Discuss any concerns about driving safety with your doctor, who can advise you based on your individual response to the medication.
Weight gain is listed as a common side effect of Sensaval (affecting up to 1 in 10 people). However, nortriptyline typically causes less weight gain than amitriptyline and some other tricyclic antidepressants, largely because it has less antihistaminergic (H1 receptor blocking) activity, which is the main driver of TCA-associated weight gain. If weight gain becomes a concern, discuss it with your doctor. Strategies to manage medication-related weight gain include maintaining a balanced diet and regular physical activity.
Sensaval (nortriptyline) is not addictive in the traditional sense—it does not produce euphoria, craving, or drug-seeking behaviour. However, if you have been taking it for an extended period, your body does become physiologically accustomed to it. Stopping abruptly can therefore cause discontinuation (withdrawal) symptoms such as headache, malaise, irritability, nausea, and sleep disturbances. This is why your doctor will always recommend a gradual dose reduction (tapering) when it is time to stop treatment, rather than stopping suddenly.
Although the approved indication for Sensaval is depression, nortriptyline is widely prescribed off-label for neuropathic (nerve) pain and migraine prevention. International guidelines from NICE and the International Association for the Study of Pain recommend nortriptyline as a first-line treatment for neuropathic pain. For these conditions, doses are typically lower than those used for depression, often starting at 10–25 mg at bedtime. If your doctor has prescribed Sensaval for pain or migraine prevention, it reflects well-established clinical practice supported by substantial evidence.
