Buy Piriton Tablets - 500 Tablets 

Piriton tablets are drowsy antihistamines that treat hay fever and other allergy symptoms. Each tablet contains 4mg of chlorphenamine maleate, a first-generation antihistamine that blocks histamine, the substance responsible for allergy symptoms like itching, swelling and a runny nose. By blocking histamine receptors, it effectively relieves discomfort and skin rashes. 

Directions

Always take Piriton tablets exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

For adults and children over 12 years old:

Take 1 tablet every 4-6 hours as needed. Do not take more than 6 tablets in 24 hours.

For children 6-12 years old:

Give your child half a tablet every 4-6 hours as needed. Do not give them more than 6 half tablets in 24 hours.

Do not take these tablets for more than 14 days without talking to your doctor first.

Piriton Side effects

  • Drowsiness
