Dicycloverine is an antispasmodic medicine which is used to relieve cramps in the stomach and intestines. It helps to ease bloating and the spasm-type pain that can be associated with irritable bowel syndrome and diverticular disease. It works by causing the muscles of the gastrointestinal system to relax.
Dicycloverine is available on prescription and you can also buy it from a pharmacy, without a prescription.
Before taking dicycloverine
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking dicycloverine it is important that your doctor or pharmacist knows:
- If you are pregnant or breastfeeding.
- If you have prostate gland problems.
- If you have any other digestive system problems, such as reflux disease, diarrhoea, ulcerative colitis, or severe constipation.
- If you have high blood pressure, or if you have recently had a heart attack.
- If you have glaucoma. This is a condition where the pressure in your eyes is raised.
- If you have been told by a doctor that you have a fast heart rate.
- If you have Down's syndrome.
- If you are less than 18 years old or over 65 years old.
- If you have been told you have nerve damage, a condition called autonomic neuropathy.
- If you have a condition that causes muscle weakness, called myasthenia gravis.
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to take dicycloverine
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about dicycloverine and will provide you with a full list of the side-effects which you may experience from taking it.
- There are two strengths of tablet available (10 mg and 20 mg) and one strength of liquid medicine (10 mg/5 ml).
- Take dicycloverine as directed on the label. The usual adult dose of dicycloverine is one 10 mg tablet, or one 5 ml spoonful of liquid medicine, three times a day. If dicycloverine has been prescribed for you by a doctor, your dose may be different to this, in which case take it exactly as your doctor tells you to.
- Swallow the tablets with a drink of water. You can take dicycloverine before or after meals.
- If you forget to take a dose, do not take two doses together to make up for the missed dose - just continue with the next dose when it is due.
Getting the most from your treatment
- It is generally recommended that you take dicycloverine only when necessary. So, start taking it when your symptoms flare up and stop taking it when your symptoms settle down again (this is usually within a week or two).
- If you develop any new symptoms, or if your symptoms get worse, make an appointment to see your doctor for further advice.
- If you have bought dicycloverine and your symptoms have not improved within two weeks of taking it, you should see your doctor for advice (even if you have previously been diagnosed by your doctor).
- If you buy any medicines, check with a pharmacist that they are safe to take with dicycloverine. Many medicines that can commonly be bought can increase the risk of side-effects.
