Before we start - have you read the Patient Information Leaflet (PIL) for this medicine?

The leaflet lists who should not take promethazine, how much to take, and the side effects. Ask us if you do not have a copy.

Who is this medicine for?

This medicine can only be supplied to the account holder, for their own use.

How old are you?
What is your biological sex?

We ask because it affects some safety checks (for example pregnancy).

Have you ever had an allergic or unusual reaction to promethazine or to similar antihistamines or phenothiazine medicines (for example Phenergan, Sominex)?
Are you taking, or have you taken in the last 2 weeks, an MAOI antidepressant (for example phenelzine, isocarboxazid, tranylcypromine, or moclobemide)?

MAOIs are an older type of antidepressant.

Do you have any of these: glaucoma (raised eye pressure), an enlarged prostate, or difficulty passing urine?
Do you have epilepsy or a history of seizures (fits)?
Do you have severe liver problems?
Do you have asthma, COPD, sleep apnoea, or another long-term breathing problem?
Have you been using this medicine (or a similar sleep aid or sedating antihistamine) most days for more than 2 weeks?

These medicines are intended for short-term use only.

Do you drink alcohol regularly, or take other medicines that cause drowsiness (for example sleeping tablets, strong painkillers/opioids, or other sedating antihistamines)?
Are you pregnant, trying to become pregnant, or breastfeeding?
Do you understand that promethazine causes drowsiness that can last into the next day, and that you must not drive or use machinery if you feel affected?
