Chlorpheniramine Maleate Injection 10mg/2ml (Piriton Injection)
Chlorpheniramine Maleate Injection is a fast-acting first-generation antihistamine used for the emergency treatment of severe allergic reactions. Often referred to in Nigeria by the brand name Piriton injection, this medication provides rapid relief by blocking H1 receptors to stop the effects of histamine in the body.
This specific formulation contains 10mg of Chlorpheniramine Maleate in a 2ml ampoule, which equates to a concentration of 5mg/ml.
Rapid Relief for Severe Allergic Reactions
Chlorpheniramine injection is primarily used when oral medications are not suitable or when immediate action is required. It is commonly administered for:
- Severe Allergic Reactions (Anaphylaxis): Used as an adjunct to adrenaline for life-threatening reactions.
- Hives and Angioedema: Provides sharp relief for intense itching, skin rashes, and swelling.
- Insect Bites and Stings: Effectively manages acute allergic responses to stings.
- Drug or Food Reactions: Used to treat sudden allergic responses to medications or specific foods.
Administration & Professional Use
This product is a Prescription-Only Medicine (POM) and must only be administered by a qualified healthcare professional. It can be given via:
- Intramuscular (IM) Injection
- Intravenous (IV) Injection

Healthcare providers should be aware that this is a 2ml ampoule containing 10mg (5mg/ml). This differs from the 10mg/1ml variant often found in Nigeria, so dosage volumes must be calculated carefully.
