Clarityne Tablets 10 mg are a trusted, over-the-counter (OTC) non-drowsy antihistamine formulated for adults and children aged 12 years and above. Each pack contains 10 film-coated tablets, providing a ten-day supply of once-daily allergy relief. Clarityne is manufactured by Organon (formerly Schering-Plough / MSD) and contains loratadine — one of the most widely prescribed and clinically validated second-generation antihistamines available globally.
Loratadine is specifically recognised for its consistently non-sedating profile at recommended doses, distinguishing it from other second-generation antihistamines such as cetirizine, which may cause drowsiness in some individuals. A single 10 mg tablet delivers full 24-hour allergy symptom control, making Clarityne one of the most practical and well-tolerated daily allergy management options available without a prescription. If you are looking to buy Clarityne 10 mg Tablets in Kenya, this product is widely available at registered pharmacies nationwide and is a leading choice for hay fever and allergy treatment in Kenya. The price of Clarityne Loratadine in Kenya is accessible, making it an affordable option for consistent allergy management.

What It Is & How It Works
Active Ingredient
Each film-coated tablet contains:
| Active Ingredient | Strength | Role |
|---|---|---|
| Loratadine | 10 mg | Second-generation selective peripheral H1 antihistamine — blocks histamine receptors to relieve allergy symptoms without significant CNS sedation |
How It Works
When the immune system encounters an allergen — such as pollen, dust mites, pet dander, mould spores, or insect stings — sensitised mast cells and basophils release histamine from their granules into surrounding tissue. Histamine then binds to H1 receptors distributed throughout the body — in the nasal mucosa, conjunctiva, skin, and upper airway — triggering the cascade of allergy symptoms including sneezing, nasal discharge, itching, and watery eyes.
Loratadine is a potent, long-acting, selective peripheral H1 receptor antagonist that works by competitively occupying H1 receptors before histamine can bind. By blocking histamine attachment at these receptor sites, loratadine prevents and relieves the histamine-driven allergy symptom cascade.
Why Loratadine Is Non-Sedating
The non-sedating characteristic of loratadine is attributable to several pharmacological properties:
- Limited blood-brain barrier penetration — loratadine is a lipophilic molecule that is efficiently excluded from the central nervous system by the P-glycoprotein efflux transporter at the blood-brain barrier, preventing significant CNS H1 receptor occupancy and thereby avoiding sedation
- High peripheral H1 selectivity — loratadine has minimal affinity for muscarinic, dopaminergic, alpha-adrenergic, or serotonergic receptors, reducing the anticholinergic and sedative side effects associated with older antihistamines
- Active metabolite desloratadine — loratadine is rapidly converted in the liver to its active metabolite desloratadine, which shares the same peripheral H1 selectivity and non-sedating profile, contributing to its prolonged 24-hour duration of action
Classification
This product is classified as an Over-the-Counter (OTC) medicine in Kenya. It can be purchased without a prescription for standard use in adults and children aged 12 years and above. Consult a pharmacist or doctor if you are unsure whether this product is suitable for you or your child.
Formulation
Film-coated tablets. Each pack contains 10 tablets. Tablets should be swallowed whole with water. May be taken with or without food.
Uses & Indications
Clarityne 10 mg Tablets may be used for the symptomatic relief of:
- Seasonal allergic rhinitis (hay fever) — sneezing, runny nose, nasal congestion, and itchy, watery eyes triggered by pollen, grass, and trees
- Perennial allergic rhinitis — year-round allergy symptoms triggered by dust mites, pet dander, cockroach allergens, and mould
- Allergic conjunctivitis — itchy, red, and watery eyes caused by airborne allergens
- Chronic idiopathic urticaria (hives) — itchy, raised skin welts of unknown cause
- Acute allergic urticaria — skin hives and rash triggered by allergens, food reactions, or insect bites
- Allergic skin itching and rash — including dermographism and contact allergic reactions
- Insect bite and sting reactions — relief of localised itching, redness, and mild swelling associated with allergic responses
IMPORTANT: Clarityne is intended for the relief of mild to moderate allergy symptoms. It is NOT intended for the treatment of severe allergic reactions (anaphylaxis), acute severe asthma, or angioedema involving the throat or airway — these are life-threatening medical emergencies requiring immediate medical attention, adrenaline (epinephrine) administration, and emergency services. Seek emergency care without delay in these situations.
Dosage & Administration
NOTE: Use only as directed on the label or by a pharmacist. Do not exceed the recommended dose or duration of use.

Administration Instructions
- Swallow the tablet whole with a full glass of water
- May be taken with or without food — food does not significantly affect the absorption of loratadine
- Take at the same time each day to maintain consistent 24-hour allergy coverage
- For seasonal allergies, begin use at the onset of the allergy season or just before for best preventive effect
- Do not take more than one tablet in any 24-hour period
- If a dose is missed, take it as soon as you remember — if it is almost time for the next dose, skip the missed dose and continue as normal; do not double dose
- For chronic conditions such as perennial allergic rhinitis or chronic urticaria, consult a healthcare provider regarding the appropriateness of long-term use beyond 6 weeks
Possible Side Effects
Like all medicines, Clarityne 10 mg Tablets may cause side effects in some people. These are generally very mild and uncommon at recommended doses. Stop use and consult your pharmacist or doctor if you experience any of the following:
Common
- Headache — mild and usually transient
- Dry mouth — mild; less pronounced than with first-generation antihistamines
- Fatigue — mild; loratadine is one of the least sedating antihistamines but very mild tiredness may occasionally occur
- Nausea
Less Common
- Drowsiness — rare at recommended doses; loratadine is clinically categorised as non-sedating; however, individual responses vary and some patients may experience mild sedation
- Stomach discomfort or gastritis
- Palpitations or tachycardia — uncommon; reported rarely
- Elevated liver enzymes — very rare; monitor in patients with pre-existing hepatic impairment
WARNING: Rare but serious — seek immediate medical attention if you experience: severe allergic reactions to loratadine itself (rash, swelling of the face, lips, tongue, or throat, difficulty breathing or anaphylaxis — rare but reported), severe skin reactions, or signs of liver dysfunction (yellowing of the skin or eyes, dark urine, or persistent abdominal pain). Although loratadine is generally very well tolerated, these rare reactions require prompt medical evaluation.
This is not a complete list of side effects. Consult a pharmacist or doctor for full information.
Warnings & Precautions
CONTRAINDICATION: Do NOT use Clarityne if you are known to be allergic to loratadine, desloratadine, or any excipient in this formulation.
Do Not Use If You:
- Are allergic to loratadine, desloratadine, or any ingredient in this product
- Are under 2 years of age without specific medical advice
- Have been advised to avoid antihistamines by your healthcare provider
Use With Caution If You Have:
- Severe liver disease or hepatic impairment — loratadine is extensively metabolised by the liver (CYP3A4 and CYP2D6); dose reduction to every-other-day dosing is required in severe hepatic impairment to prevent drug accumulation
- Severe renal impairment — similar dose reduction to every-other-day dosing is recommended; consult a doctor before use
- Phenylketonuria (PKU) — check the tablet excipients on the label for phenylalanine content if applicable
- Rare hereditary conditions including galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption — check excipient content with your pharmacist
Do Not Combine With (Selected Key Interactions):
- Medicines that inhibit CYP3A4 or CYP2D6 enzymes — including ketoconazole, itraconazole, erythromycin, clarithromycin, and cimetidine — these may increase loratadine plasma levels; monitor for increased side effects
- Alcohol — although loratadine is non-sedating, concurrent alcohol use may enhance any residual CNS effects; patients should exercise caution
- Other antihistamines — combined use increases the risk of antihistamine side effects without additional therapeutic benefit
CLINICAL NOTE (Kenya-specific): Clarityne (loratadine) is particularly well suited to the Kenyan patient population due to its consistently non-sedating profile — an important consideration in a workforce where a significant proportion of adults are engaged in manual labour, operation of machinery, commercial driving, and agricultural activities where cognitive and psychomotor performance is critical to safety. Dust mite allergens, cockroach allergens, outdoor moulds, and grass pollens are significant perennial and seasonal triggers across Kenya — particularly in Nairobi, the Rift Valley, and the Coast regions — making once-daily long-acting antihistamine therapy clinically valuable for ongoing allergy management. Pharmacists dispensing Clarityne in Kenya should counsel patients on the importance of identifying and reducing allergen exposure alongside pharmacological treatment, as medication alone provides symptom relief but does not address the underlying sensitisation. Patients with frequent or worsening allergy symptoms should be referred for formal allergy assessment and consideration of allergen immunotherapy.
Keep out of reach of children. In case of accidental overdose, contact a poison control centre or emergency services immediately.
