About peppermint oil capsules
|Type of medicine||An antispasmodic medicine|
|Used for||Relief of tummy (abdominal) pain and bloating associated with conditions like irritable bowel syndrome (in adults)|
|Also called||Apercap®; Colomint®; Colpermin®; Mintec®|
Food moves through your intestines because some of the muscles in your bowel contract and then relax in a regular way. These muscle contractions move the food along. In conditions such as irritable bowel syndrome, the muscle contractions can occur too often or become painful. This causes symptoms such as pain and bloating. Smooth muscle relaxants like peppermint oil work on the muscles in the bowel to cause them to relax. This helps to relieve the pain and discomfort.
You can buy peppermint oil capsules 'over the counter' for the management of conditions like irritable bowel syndrome. They can be bought without a prescription at pharmacies and other retail outlets.
Before taking peppermint oil capsules
To make sure that this is the right treatment for you, it is important that you speak with a doctor or pharmacist before you start taking peppermint oil capsules if:
- You are pregnant or breast-feeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.
- You have severe constipation.
- You have passed any blood from your bowels, or if you have had any abnormal vaginal bleeding.
- You feel sick or have lost your appetite, or if you have recently lost weight.
- You feel or look unwell.
- You have recently travelled abroad.
- You have difficulty or pain when you pass urine.
- You are 40 years of age or over and it is some time since your last attack, or if your symptoms have changed since your last attack.
- 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.
- You have ever had an allergic reaction to a medicine, or if you are allergic to menthol, peanuts or soya.
How to take peppermint oil capsules
- Before taking the capsules, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about peppermint oil, and it will also provide you with a full list of the side-effects which you could experience from taking it.
- Take the capsules exactly as directed on the label, or as directed by your doctor or pharmacist. The usual dose is one or two capsules taken three times each day. If possible, take the capsules about an hour or so before meals - you should not take them straight after food.
- Swallow the capsules with a drink of water. Do not open or chew the capsules.
- If you forget to take a dose, do not worry, just take the next dose when it is due. Do not take two doses together to make up for a missed dose.
Getting the most from your treatment
- It is generally recommended that you take peppermint oil capsules only when necessary. So, start taking the capsules when your symptoms flare up, and continue to take them until you feel better. Stop taking the capsules when your symptoms settle down again (this is usually within a week or two).
- There are some lifestyle and dietary changes that could help your condition. The general advice is to increase the amount of physical activity you do, to eat regularly without missing meals or leaving long gaps between your meals, and to limit the amount of fresh fruit you eat to no more than three portions a day. You may also want to think about the dietary fibre you eat - some people find reducing the amount of bran eaten and increasing the amount of oats eaten each day can be beneficial. Try to drink several large glasses of water each day, and reduce your intake of caffeinated drinks, alcohol and fizzy drinks.
- If you develop any new symptoms, or if your symptoms become worse, make an appointment to see your doctor for advice (even if you have previously been diagnosed by your doctor).
- Drinking alcohol while you are taking peppermint oil capsules can increase the chance that you experience side-effects. If this happens, you are advised to not drink alcohol.
- Do not take indigestion remedies during the two hours before you take peppermint oil, or during the two hours after you have taken it. This is because indigestion remedies interfere with the capsules and stop them from working as intended.
- Not everybody with irritable bowel syndrome finds that antispasmodics like peppermint oil capsules work well for them. Some people respond better to other types of antispasmodic medicines. If your symptoms do not improve, it is worth trying a different kind of antispasmodic. Ask your pharmacist for advice about what treatments would be suitable for you.
