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.

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 should 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.

    Things you must do

    Tell any other doctors, dentists, and pharmacists who are treating you that you are taking Phenergan.

    If you are about to be started on any new medicine, tell your pharmacist or doctor that you are taking Phenergan.

    If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking this medicine.

    If you become pregnant while you are taking this medicine, stop taking it and tell your doctor immediately.

    Talk to your pharmacist or doctor if your symptoms do not improve. Your pharmacist or doctor will assess
    your condition and decide if you should continue to take the medicine.

    Things you must not do

    Do not give Phenergan to anyone else, even if they have the same condition as you.

    Do not take Phenergan to treat any other complaints unless your pharmacist or doctor tells you to.

    Do not drink alcohol while taking Phenergan. The sedation effects of alcohol may be increased.

    Do not take more than the recommended dose unless your pharmacist or doctor tells you to.

    Things to be careful of

    Phenergan is a known sedative and may cause drowsiness in some people.

    Make sure you know how you react to Phenergan before you drive a car, operate machinery, or do anything else that could be dangerous if you are drowsy. If this occurs do not drive or operate machinery. If you have a single dose at bedtime, you may still be affected in the morning.

    Avoid alcohol.

    Children and the elderly are especially sensitive to the effects of antihistamines.

    Storage

    Keep your medicine in the pack until it is time to take it. If you take your medicine out of the pack it will not keep as well.

    Keep your tablets in a cool dry place where the temperature stays below 30 °C.

    Keep your elixir in a cool dry place, protected from light, where the temperature stays below 25 °C.

    Do not store Phenergan or any other medicine in the bathroom or near a sink. Do not leave it in the car on hot days or on window sills. Heat and dampness can destroy some medicines.

    Keep it where children cannot reach it. A locked cupboard at least
    one-and-a-half metres above the ground is a good place to store medicines.
