Who may not be able to take chlorphenamine
Chlorphenamine is not suitable for some people. To make sure it's safe for you, tell your doctor or pharmacist if you:
- have ever had an allergic reaction to chlorphenamine or any other medicine
- have an eye problem called primary angle closure glaucoma
- have taken a type of antidepressant called monoamine oxidase inhibitors in the last 14 days
- have problems peeing or emptying your bladder
- have epilepsy or another health problem that can cause fits or seizures
- have breathing difficulties such as asthma or a lung condition
- have heart disease or very high blood pressure
- have an enlarged prostate
- have liver or kidney problems
- are due to have an allergy test, as taking chlorphenamine may affect the results, so you might need to stop taking it a few days before the test – ask a pharmacist or your doctor for advice
- are unable to have any alcohol – some liquid chlorphenamine products contain a very small amount of alcohol, so check the ingredients and the packaging carefully
- are a frail, older adult – you may have more side effects, such as confusion
