Peppermint oil

About peppermint oil

Peppermint oil works by acting on the smooth muscle in the gut to cause it to relax. This reduces painful cramps and muscle spasms. It is particularly useful in treating these symptoms in irritable bowel syndrome (IBS) and similar conditions.

Before taking peppermint oil

Before taking peppermint oil make sure your doctor or pharmacist knows:

• If you are allergic to menthol.
• If you suffer from paralytic ileus (a condition where the intestine is paralysed).
• If you are allergic to peanuts or soya (Colpermin contains peanut oil).
• If this is the first time you have experienced these symptoms (for confirmation of IBS).
• If you are aged 40 years or over and it is some time since the last attack or your symptoms have changed.
• If blood has been passed from the bowel.
• If you have a feeling of sickness, vomiting, loss of appetite or loss of weight.
• If you have been feeling tired, have severe constipation or a fever.
• If you have recently travelled abroad.
• If you have had abnormal vaginal bleeding or discharge.
• If you have experienced difficulty or pain in passing urine.
• If you are pregnant, trying for a baby or breast-feeding.

How to take peppermint oil

• Take peppermint oil exactly as directed by your doctor.
• Try to take peppermint oil at the same times each day to avoid missing any doses.
• Swallow each peppermint oil capsule whole, not crushed or chewed, with water.
• Take peppermint oil capsules half to one hour before each meal.
• If you miss a dose of peppermint oil, take it as soon as possible. If it is almost time for your next dose, then skip the missed dose and continue taking at the usual times. Never take two doses at the same time to compensate.

Getting the most from your treatment

• Do not take indigestion remedies at the same time of day as peppermint oil. Take these at least two hours before or two hours after a dose of peppermint oil.
• Keep your regular appointments with your doctor so your progress can be monitored.

Can peppermint oil cause problems?

Along with their useful effects all medicines can cause unwanted side effects, which usually improve as your body adjusts to the new medicine. Speak with your doctor or pharmacist if any of the following side effects continue or become troublesome.

Very occasionally people can have an allergic reaction to peppermint oil. Signs of an allergic reaction are rash, headache, shaking, unsteadiness and a slow heart rate. If you experience these or any other worrying symptoms, which you think may be due to this medicine, discuss them with your doctor or pharmacist.
