How It Works
Piriton contains Chlorpheniramine, which blocks H1 histamine receptors in the body. When allergens trigger histamine release, Chlorpheniramine prevents histamine from binding to receptors, thereby reducing allergic symptoms like sneezing, itching, and inflammation. It also has mild sedative properties due to its ability to cross the blood-brain barrier.

| Children 6-12 | ½ tablet 2-3× daily | 3 tablets daily |
Take Piriton with water, preferably with food to reduce stomach irritation. Space doses evenly throughout the day for optimal symptom control.
Duration of Action
Piriton begins working within 30-60 minutes of administration. Peak effects occur at 2-4 hours, with symptom relief lasting 4-6 hours per dose. For seasonal allergies, regular dosing provides consistent protection throughout allergy season.
Side Effects
Common side effects include drowsiness, dry mouth, blurred vision, and mild dizziness. Some patients experience constipation, difficulty urinating, or increased appetite. Drowsiness is the most frequent side effect and may impair driving ability.
Warning
Piriton causes significant drowsiness and may impair driving or operating machinery. Avoid alcohol consumption while taking this medication. Not recommended for children under 6 years without medical supervision. Elderly patients may be more sensitive to side effects, particularly confusion and dizziness.
Pregnancy and Breastfeeding
Piriton should be used during pregnancy only if clearly needed, preferably after the first trimester. Chlorpheniramine passes into breast milk in small amounts. Breastfeeding mothers should consult healthcare providers, as the medication may reduce milk production or cause drowsiness in infants.
Interaction

- May increase effects of tricyclic antidepressants
- Possible reduced effectiveness of certain blood pressure medications
- May interact with MAO inhibitors causing dangerous reactions
- Could mask symptoms when used with ototoxic medications
Precaution
Use with caution in patients with glaucoma, enlarged prostate, breathing problems, or liver disease. Elderly patients require reduced dosages due to increased sensitivity. Avoid prolonged use without medical supervision. Stop taking 48 hours before allergy skin tests as it may interfere with results.
Important Information
Piriton may cause drowsiness lasting into the next day. Avoid driving until you know how the medication affects you. Don’t exceed recommended dosage as it may increase side effects without improving effectiveness. Store in a cool, dry place away from children. Consult a pharmacist or doctor if symptoms persist beyond one week of treatment.
