What is in this leaflet

This leaflet answers some common questions about Phenergan.

It does not contain all the available information. It does not take the place of talking to your pharmacist or doctor.

All medicines have risks and benefits. Your pharmacist or doctor has weighed the risks of you taking Phenergan against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your pharmacist or doctor.

Keep this leaflet with the medicine.

You may need to read it again.

What Phenergan is used for

Phenergan is an antihistamine used to treat a number of conditions:

allergies - allergic contact dermatitis, hives, hayfever, bites and stings

respiratory symptoms due to allergies - runny nose

nausea and vomiting - motion sickness

assists in the management of the symptoms of chicken pox and measles by acting as a sedative

for short-term use for sedation on the advice of a pharmacist or doctor - do not use for more than 7-10 days

Antihistamines help reduce allergic symptoms by preventing the effects of a substance called histamine. Histamine is produced by the body in response to foreign substances that the body is allergic to.

Your pharmacist or doctor may have recommended Phenergan for another reason.

Ask your pharmacist or doctor if you have any questions about this medicine.

Phenergan must not be used in children under 2 years of age, due to the potential for fatal respiratory depression.

This medicine may affect your ability to drive a car or operate machinery.
