Piriton Syrup
(Chlorphenamine Maleate)

Uses of Piriton

This liquid form of piriton for children is used in the relief and treatment of the following conditions:

  • symptoms of hayfever in children
  • Hives and Nettle Rashes
  • Insect bites
  • Itching associated with chicken pox
  • Food allergies
  • Drug allergies
  • General

  • 2 to 5 years, take 2.5mls 4 to 6 times a day. Maximum allowed dose for this age group is 15mls or 6mg in a day.
  • 6 to 12 years old children should take 5mls of piriton liquid syrup 4 to 6 times daily. They should take no more than 30mls maximum in any given 24 hour period. This is the maximum dose allowed.
  • Children above 12 years of age and adults can take 10mls of piriton syrup 4 to 6 times daily. The maximum daily dose of piriton for this age group would be 60mls in total (that is 24mg) in any 24 hours.

Side Effects of Piriton

The side effects of piriton include

  • Drowsiness
  • Hyperactivity in children (sleeplessness, irritability, nightmares and rarely convulsion in some children. These side effects are very rare though, but if they occur while on piriton, you should report this to your doctor).
  • Blurred vision
  • Dry mouth
  • Allergic reaction - yes.

    Piriton is used in the treatment of allergic reactions, but in some people, it in itself, can precipitate an allergic reaction. This allergy might be to the active ingredient chlorphenamine, or other components of the syrup like the E preservatives.
  • Haemolytic anaemia - this could lead to passage of deep yellow or dark urine. This side effect is very rare.

The above listed side effects are quite uncommon. The only side effect of piriton frequently seen is sedation or drowsiness.


When using chlorphenamine malate syrup, be sure not to take it with other medicines bought over the If you or your child has diabetes, be careful with the use of piriton syrup because of the sucrose content. Sticking to the treatment dose should be okay, especially in younger children. It is when large amount is taken like 10mls 4 to 6 times a day, as in older children and adults that the amount of sucrose in the syrup might become an issue in some diabetics.
