How It Works

Chlorphenamine is a first-generation antihistamine that works by blocking histamine H1 receptors in the body. Histamine is a natural chemical released during an allergic reaction that causes symptoms such as sneezing, itching, watery eyes, and a runny nose. By blocking histamine’s effects, chlorphenamine helps to reduce and relieve these uncomfortable symptoms.

Interactions

Chlorphenamine may interact with other medicines that cause drowsiness, including sleeping tablets, anxiety medicines, antidepressants, and some pain relievers. It can also interact with MAOIs, tricyclic antidepressants, and anticholinergic medicines (such as those used for bladder or stomach problems), potentially increasing side effects. Phenytoin (an anti-epileptic medicine) levels in the blood may also be affected. Tell your PillSorted pharmacist or doctor about all medicines you are currently taking, including herbal remedies and supplements.

⸻

Pregnancy and Breastfeeding

Chlorphenamine is not recommended during the third trimester of pregnancy, as it may affect newborns. There is limited safety data for use in early pregnancy, and the medicine may pass into breast milk, potentially causing sedation in a breastfed baby. Speak to your doctor or PillSorted pharmacist before use if you are pregnant, trying to conceive, or breastfeeding.

⸻

Alcohol

You should avoid drinking alcohol whilst taking chlorphenamine. Alcohol can significantly increase the sedative (drowsiness-causing) effect of this medicine, making you feel much more sleepy or impaired than usual. This can be dangerous, particularly if you need to drive or operate machinery.

⸻

Driving and Operating Machinery

Chlorphenamine is a sedating antihistamine and can cause significant drowsiness, dizziness, and blurred vision. You should not drive, cycle, or operate heavy machinery until you know how this medicine affects you. If you feel drowsy or unwell after taking this medicine, do not drive or use machinery.
