Zyx Orange & Honey (Benzydamine)

What Is Zyx Orange & Honey and What Is It Used For?

Zyx Orange & Honey is an over-the-counter lozenge containing benzydamine hydrochloride 3 mg, a locally acting anti-inflammatory medication used to relieve pain and irritation in the mouth and throat. It is suitable for adults and children over 6 years of age and provides rapid symptomatic relief from sore throat, pharyngitis, tonsillitis, and minor mouth ulcers.

Benzydamine hydrochloride, the active ingredient in Zyx Orange & Honey, belongs to the group of non-steroidal anti-inflammatory drugs (NSAIDs). However, unlike conventional systemic NSAIDs such as ibuprofen or naproxen, benzydamine is designed primarily for local (topical) use in the oral cavity and pharynx. It was first synthesised in Italy in the 1960s and has been used clinically for over five decades across Europe, Asia, and Latin America. The drug is marketed under various brand names worldwide, including Tantum Verde, Difflam, and the Zyx range of lozenges.

Benzydamine has a unique pharmacological profile that distinguishes it from other NSAIDs. At the concentrations achieved through topical application, it does not significantly inhibit cyclooxygenase (COX-1 or COX-2), which is the primary mechanism of most systemic NSAIDs. Instead, benzydamine works through several complementary mechanisms: it stabilises cell membranes, inhibits the release of pro-inflammatory cytokines (including tumour necrosis factor alpha and interleukin-1 beta), reduces prostaglandin synthesis locally, and provides a direct local anaesthetic effect on the mucous membranes. This local anaesthetic action contributes to the rapid pain relief that patients typically experience within minutes of using the lozenge.

The Zyx Orange & Honey lozenge is specifically formulated to dissolve slowly in the mouth, allowing the benzydamine to maintain prolonged contact with the inflamed oral and pharyngeal mucosa. Each lozenge contains 3 mg of benzydamine hydrochloride (equivalent to 2.68 mg of benzydamine base). The orange and honey flavouring provides a pleasant taste that improves patient compliance, particularly important in older children and adolescents who may be reluctant to take medication for sore throat.

Zyx Orange & Honey lozenges are indicated for the following conditions:

• Acute sore throat (pharyngitis): The most common reason for use, providing relief from the pain, inflammation, and irritation associated with viral and bacterial pharyngitis
• Tonsillitis: Symptomatic relief of pain and swelling associated with inflamed tonsils
• Mouth ulcers (aphthous stomatitis): Reduction of pain and inflammation from oral ulcers
• Post-dental procedure discomfort: Relief of pain following dental extractions or other oral surgical procedures
• Oral mucositis: Benzydamine-containing products are widely used to manage oral mucositis caused by radiation therapy or chemotherapy, though the lozenge form may be less suitable for severe cases where mouth rinses are preferred

It is important to note that Zyx Orange & Honey treats symptoms only and does not address the underlying cause of sore throat. If your sore throat is caused by a bacterial infection (such as group A streptococcus), you may need antibiotic treatment in addition to symptomatic relief. You should consult a doctor if your symptoms do not improve within 3 days, if they worsen at any point, or if you develop a fever or other new symptoms.

What Should You Know Before Taking Zyx Orange & Honey?

Before using Zyx Orange & Honey, check that you are not allergic to benzydamine or any of the other ingredients in the lozenge. Use with caution if you have asthma or a history of NSAID sensitivity. Do not use during pregnancy or breastfeeding. Consult a doctor if symptoms persist beyond 3 days.

Although Zyx Orange & Honey is an over-the-counter medication with a well-established safety profile, there are important considerations that should be assessed before use. Because benzydamine is applied locally and has minimal systemic absorption from the lozenge form, the risk of serious adverse effects is low. However, certain groups of patients require additional caution.

Contraindications

You must not take Zyx Orange & Honey if you have a known allergy (hypersensitivity) to benzydamine hydrochloride or any of the other ingredients in the lozenge (listed in the ingredients section below). Signs of an allergic reaction may include skin rash, itching, swelling of the face or throat, or difficulty breathing. If you have previously experienced an allergic reaction to any benzydamine-containing product (including Tantum Verde, Difflam, or other Zyx variants), you should not use this product.

Warnings and Precautions

Talk to your doctor or pharmacist before using Zyx Orange & Honey if any of the following apply to you:

• Asthma or history of bronchospasm: Benzydamine, like other NSAIDs, may in rare cases trigger bronchospasm (sudden tightening of the airways) in susceptible individuals. If you have asthma or have previously experienced bronchospasm after taking aspirin, ibuprofen, or other NSAIDs, use benzydamine lozenges with caution and seek medical advice first.
• NSAID sensitivity: If you are allergic to or intolerant of other NSAIDs such as acetylsalicylic acid (aspirin), diclofenac, ibuprofen, or naproxen, you should speak with a healthcare professional before using benzydamine. Although cross-reactivity is uncommon due to benzydamine's primarily local action, it cannot be completely excluded.
• Sugar intolerance: Zyx Orange & Honey lozenges contain isomalt (E 953), a sugar alcohol. If you have been told by your doctor that you have an intolerance to certain sugars, consult your doctor before using this product.
• Persistent or worsening symptoms: In rare cases, ulceration of the mouth or throat may be a sign of a more serious underlying condition. If your sore throat worsens, does not improve within 3 days of using the lozenges, or is accompanied by fever, difficulty swallowing, or other systemic symptoms, you should seek medical or dental advice promptly.

Pregnancy and Breastfeeding

If you are pregnant, breastfeeding, think you may be pregnant, or are planning to have a baby, seek advice from your doctor or pharmacist before using Zyx Orange & Honey lozenges. As a precautionary measure, benzydamine lozenges should not be used during pregnancy or while breastfeeding.

Although systemic absorption of benzydamine from the lozenge form is minimal, there are insufficient data from clinical studies to establish the safety of benzydamine during pregnancy and lactation. Animal reproductive toxicology studies have not demonstrated direct harmful effects on fertility, embryonic development, or postnatal development, but these findings cannot be directly extrapolated to human pregnancy. Given that sore throat is typically a self-limiting condition with alternative treatment options available, the precautionary principle applies.

If you need pain relief for a sore throat during pregnancy, consult your doctor or pharmacist who can recommend suitable alternatives such as paracetamol (acetaminophen), warm salt water gargles, or other non-pharmacological measures.

Driving and Using Machines

Zyx Orange & Honey has no known effect on the ability to drive or operate machinery. Benzydamine lozenges act locally in the mouth and throat with minimal systemic absorption, and no central nervous system effects have been reported at recommended doses. However, as with all medications, you are personally responsible for assessing whether you are fit to drive or perform tasks requiring alertness.

Important Information About Certain Ingredients

Zyx Orange & Honey lozenges contain several excipients that may cause reactions in sensitive individuals:

• Isomalt (E 953): A sugar alcohol used as a sweetener. If you have been told by your doctor that you have an intolerance to certain sugars, contact your doctor before taking this product.
• Sunset yellow FCF (E 110): A colouring agent (also known as para-orange or Orange Yellow S) that may cause allergic reactions in some people, including those with aspirin sensitivity.
• Orange flavouring: Contains citral, citronellol, d-limonene, geraniol, and linalool. These naturally occurring aromatic compounds may cause allergic reactions in sensitive individuals.

How Does Zyx Orange & Honey Interact with Other Drugs?

Benzydamine lozenges have no known clinically significant drug interactions. Because the lozenge delivers benzydamine primarily to the local oral and pharyngeal mucosa with minimal systemic absorption, the risk of interactions with other medications is extremely low. No dose adjustments are required when taking other medicines.

One of the significant advantages of benzydamine as a locally acting NSAID is its excellent drug interaction profile. Unlike systemic NSAIDs (such as ibuprofen, naproxen, or diclofenac), which can interact with anticoagulants, antihypertensives, lithium, methotrexate, and other drugs through systemic pharmacokinetic and pharmacodynamic mechanisms, benzydamine lozenges deliver the active ingredient primarily to the local site of action. The amount of benzydamine absorbed systemically from a 3 mg lozenge is negligible and well below the levels that would be expected to produce any systemic pharmacological effects or drug interactions.

Systematic reviews of benzydamine's pharmacological profile have confirmed that it does not significantly inhibit cytochrome P450 (CYP) enzymes at clinically relevant concentrations, which are the enzymes responsible for the metabolism of most drugs in the liver. Furthermore, benzydamine does not significantly affect platelet aggregation or bleeding time at topical doses, unlike systemic NSAIDs which are well known to increase bleeding risk.

The following table provides a summary of theoretical considerations regarding benzydamine and other drug classes. These are included for completeness and transparency, though none represent clinically significant interactions when benzydamine is used in lozenge form at recommended doses:

In clinical practice, benzydamine lozenges are frequently used alongside systemic analgesics (paracetamol, ibuprofen), antibiotics (when bacterial infection is confirmed), and other throat remedies without any reported interactions. This makes benzydamine an ideal adjunctive therapy for sore throat management, where the local anti-inflammatory and anaesthetic effects complement the systemic action of other medications.

If you are taking any medication for a chronic condition and are uncertain about whether it is safe to use Zyx Orange & Honey, consult your pharmacist or doctor. While no interactions are expected, individualised advice is always appropriate for patients on complex medication regimens.

What Is the Correct Dosage of Zyx Orange & Honey?

Adults and children over 6 years: dissolve 1 lozenge slowly in the mouth, 3 times daily. Do not exceed 3 lozenges per day. Do not chew or swallow whole. Treatment should not continue for more than 7 days without consulting a doctor.

Always use Zyx Orange & Honey exactly as described in the patient information leaflet or as directed by your doctor or pharmacist. The lozenge should be placed in the mouth and allowed to dissolve slowly. It should not be chewed or swallowed whole, as this would reduce the duration of local contact with the inflamed mucosa and decrease the therapeutic effect.

Adults

For optimal effectiveness, space the lozenges evenly throughout the day. The local anaesthetic effect provides relief within minutes of starting to dissolve the lozenge, while the anti-inflammatory effects build up over the course of treatment. Taking the lozenge after meals can help ensure prolonged contact with the pharyngeal mucosa without interference from food or drink.

Children

Elderly Patients

No dose adjustment is required for elderly patients. The recommended dose of 1 lozenge 3 times daily applies equally to older adults. Because systemic absorption of benzydamine from lozenges is minimal, there are no specific concerns regarding age-related changes in kidney or liver function that would necessitate dose modification. However, elderly patients should be reminded to dissolve the lozenge slowly and not to chew or swallow it whole.

Missed Dose

If you forget to take a dose, take it as soon as you remember. If it is nearly time for your next scheduled dose, skip the missed dose and continue with your normal dosing schedule. Do not take a double dose to compensate for a missed one. Since Zyx Orange & Honey is used for symptomatic relief, missing a dose simply means a temporary gap in pain relief.

Overdose

If you accidentally take more than the recommended dose, or if a child has accidentally ingested the lozenges, contact a doctor, hospital emergency department, or poison control centre immediately for advice on the risk and appropriate management.

There are very rare reports of children becoming agitated, experiencing seizures, sweating, involuntary muscle movements (ataxia), tremors, and vomiting after ingesting benzydamine doses approximately 100 times higher than the lozenge strength. At recommended topical doses, the risk of systemic toxicity is negligible. However, accidental ingestion of multiple lozenges by a child warrants medical evaluation as a precaution.

What Are the Side Effects of Zyx Orange & Honey?

Like all medicines, Zyx Orange & Honey can cause side effects, though not everyone gets them. Side effects are generally mild and local in nature. The most commonly reported effects include photosensitivity (skin sensitivity to sunlight), a burning sensation in the mouth, and dry mouth. Serious allergic reactions are very rare but require immediate medical attention.

Benzydamine lozenges have an excellent safety profile owing to their primarily local action and minimal systemic absorption. Extensive post-marketing surveillance data spanning over five decades of clinical use have confirmed that serious adverse effects are exceedingly rare. The side effects listed below are based on reports from clinical trials and post-marketing experience, organised by frequency according to internationally standardised definitions.

Understanding Photosensitivity

Photosensitivity is the most commonly reported side effect of benzydamine, although it remains uncommon (affecting fewer than 1 in 100 users). This reaction manifests as an exaggerated sunburn or skin rash upon exposure to sunlight or ultraviolet (UV) radiation. If you experience this side effect, you should avoid direct sunlight and UV exposure, use sunscreen with a high SPF, and wear protective clothing. The photosensitivity typically resolves after discontinuation of benzydamine.

The mechanism behind benzydamine-induced photosensitivity is thought to involve the generation of reactive oxygen species when benzydamine molecules in the skin are exposed to UV light. While this side effect is more commonly associated with systemic benzydamine use, it has been reported rarely with the topical lozenge form as well.

Local Oral Effects

The burning sensation and numbness (oral hypoaesthesia) that some users experience are directly related to benzydamine's local anaesthetic properties. These effects are generally mild, transient, and self-limiting. Drinking a small amount of water can help alleviate a burning sensation. The numbness is actually part of the desired therapeutic effect, as it contributes to pain relief in the throat. These sensations typically last only for the period during which the lozenge is being dissolved and for a short time afterwards.

Reporting Side Effects

If you experience any side effects, including those not listed here, talk to your doctor or pharmacist. You can also report side effects to your national medicines regulatory authority. Reporting helps improve knowledge about the safety of medications and ensures that the benefit-risk profile remains favourable for all patients.

How Should You Store Zyx Orange & Honey?

Store below 30°C in the original packaging to protect from moisture. Keep out of sight and reach of children. Do not use after the expiry date on the carton. Dispose of unused lozenges at your pharmacy.

Proper storage of medication is essential to maintain its effectiveness, quality, and safety throughout its shelf life. Zyx Orange & Honey lozenges should be stored at room temperature, not exceeding 30°C (86°F). The lozenges are sensitive to moisture, so they should be kept in their original packaging (PVC/PE/PVDC-aluminium blister packs or paraffin-coated paper wrappers) until ready to use.

Avoid storing the lozenges in bathrooms, kitchens, or other areas where humidity levels are high, as moisture can affect the integrity and dissolution properties of the lozenge. Do not remove lozenges from the blister pack in advance; only open the pack when you are ready to take a dose.

Always keep Zyx Orange & Honey and all medicines out of the sight and reach of children. The pleasant orange and honey flavour may make the lozenges attractive to young children, increasing the risk of accidental ingestion. Store them in a secure location, ideally at height or in a locked medicine cabinet.

Do not use Zyx Orange & Honey after the expiry date stated on the outer carton and blister pack. The expiry date refers to the last day of the indicated month. Do not dispose of unused lozenges via wastewater or household waste. Return them to your pharmacy for proper disposal, which helps protect the environment from pharmaceutical contamination.

What Does Zyx Orange & Honey Contain?

Each Zyx Orange & Honey lozenge contains 3 mg of benzydamine hydrochloride (equivalent to 2.68 mg benzydamine) as the active ingredient. The lozenges are sugar-free, using isomalt as a sweetener, and are flavoured with orange and honey flavourings. They are orange-yellow, square-shaped with a central indentation.

Active Ingredient

The active substance is benzydamine. Each lozenge contains 3 mg of benzydamine hydrochloride, which is equivalent to 2.68 mg of benzydamine base. Benzydamine hydrochloride is a white to slightly yellowish crystalline powder with the molecular formula C₁₉H₂₃N₃O · HCl and a molecular weight of 345.87 g/mol. It is freely soluble in water, which allows for efficient dissolution and release from the lozenge matrix into the oral cavity.

Inactive Ingredients (Excipients)

The other ingredients in Zyx Orange & Honey lozenges are:

• Isomalt (E 953): A sugar alcohol used as a sweetener and bulking agent. Provides the solid matrix of the lozenge without contributing to dental caries. May have a mild laxative effect in very high doses.
• Citric acid monohydrate: An acidulant that enhances the orange flavour and helps stabilise the formulation.
• Orange flavouring: A natural flavour blend containing citral, citronellol, d-limonene, geraniol, and linalool. These terpene and terpenoid compounds provide the characteristic orange aroma and taste.
• Honey flavouring: Provides a mild honey note that complements the orange flavour.
• Levomenthol: Provides a mild cooling sensation that contributes to the soothing effect of the lozenge.
• Acesulfame potassium: An artificial sweetener approximately 200 times sweeter than sucrose, used to enhance the sweet taste without adding sugar or significant calories.
• Quinoline yellow (E 104): A yellow food colouring agent.
• Sunset yellow FCF (E 110): An orange food colouring agent (also known as para-orange). This dye may cause allergic reactions in some individuals.

Appearance and Packaging

Zyx Orange & Honey lozenges are orange-yellow, square-shaped tablets with a central indentation (depression in the middle). They are packaged in PVC/PE/PVDC-aluminium blister packs or wrapped in paraffin-coated paper. Each pack contains either 20 or 30 lozenges. Not all pack sizes may be available in all markets.
