Alverine is an antispasmodic medicine which is taken to relieve bloating and crampy pain in the lower tummy (abdomen). These symptoms are commonly associated with the gastrointestinal conditions irritable bowel syndrome and diverticular disease. Alverine can also be taken to help relieve period pain cramps. Alverine works on the muscles in the lower abdomen, causing them to relax.

Alverine capsules are available on prescription and you can buy them from a pharmacy, without a prescription, if your symptoms have previously been diagnosed by a doctor.

Before taking alverine

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 alverine it is important that your doctor or pharmacist knows:

  • If you are pregnant or breastfeeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.

  • If you have severe constipation, or if you feel your bowel is not working properly.

  • 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.
