Promethazine

About promethazine

Promethazine belongs to a group of medicines known as sedating مضادات الهيستامين المهدئة. It has several uses.

It is used to prevent (or treat) feelings of sickness (nausea). It is commonly recommended for sickness associated with travel and for vertigo.

It is also used to relieve allergies such as حمى القش و allergic skin rashes.

Promethazine also makes you feel sleepy (has a sedative effect). It may be taken (for a few days only) to help promote sleep in adults with sleeping problems. It has been popular in the past as a means of 'settling' children, but promethazine should not be used in this way.

Promethazine is available on prescription, or you can buy it without a prescription at pharmacies. It is not suitable for children under 2 years of age.

To make sure this is the right treatment for you, before you start taking promethazine it is important that you discuss the treatment with a doctor or pharmacist if:

• أنتِ حامل، تحاولين الإنجاب أو تقومين بالرضاعة الطبيعية.

• لديك مشكلة في طريقة عمل الكبد لديك، أو إذا كان لديك مشكلة في الكلى.

• You have a slow or irregular heartbeat.

• لديك حالة تسبب زيادة الضغط في عينيك، مثل الجلوكوما.

• You have prostate problems or if you have been experiencing any difficulty passing urine.

• أنت تعلم أن لديك انسدادًا في الأمعاء الدقيقة.

• لديك صرع.

• You have any long-term breathing problems, such as asthma or chronic obstructive pulmonary disease (COPD).

• You have a low level of potassium in your blood (hypokalaemia).

• أنت تتناول أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

• لقد سبق لك أن تعرضت لرد فعل تحسسي تجاه دواء.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. There are a number of different brands and strengths of promethazine tablet. The manufacturer's leaflet will give you more information about the brand you have been given. It will also contain a full list of the side-effects which you may experience from taking promethazine.

• Take promethazine exactly as your doctor or pharmacist has told you to. You may be asked to take one or more doses during a day, depending upon the reason why you are taking it.

• If you are taking promethazine to prevent travel sickness, it is usually recommended that you take the first dose at bedtime on the evening before you are due to travel. You can then take a further dose on the morning of your travel if needed.

• You can take promethazine before or after meals. Some people find it helps to swallow the tablets with a drink of water.

• If you are giving promethazine liquid medicine to a child, make sure you follow the dosing instructions on the bottle carefully so that you measure out the correct dose for the age of your child.

• Most people only need to take an antihistamine for a short while when they have symptoms. You should stop taking promethazine once your symptoms have eased. Do not take promethazine for more than a few days for sleeping problems.

• Promethazine may cause drowsiness and blurred vision. If this happens to you, do not drive and do not use tools or machines. Alcohol will make the drowsiness worse, so it is best not to drink alcohol while you are on promethazine.

• If you are pregnant, only take promethazine on the advice of your doctor. Do not take promethazine in the last two weeks before your baby is born as it could cause side-effects for your baby.

• If you are having an operation or any treatment (particularly if it is to test for an allergy), tell the person carrying out the treatment that you are taking promethazine.

• Promethazine may cause your skin to become more sensitive to sunlight than normal. Use a sunscreen that protects against UVA light and has a sun protection factor (SPF) of at least 15, especially in strong sunlight or until you know how your skin reacts. Do not use sunbeds.

• If you buy any medicines, check with a pharmacist that they are safe to take with an antihistamine. This is because a number of other medicines can interfere with the way promethazine works and can increase the risk of side-effects.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains the most common ones associated with promethazine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any continue or become troublesome.
