Xenical treatment should not be used long-term. It is there to support sustainable lifestyle changes like healthy eating, behavioural changes and increased exercise.

If you follow a low-fat diet plan, side effects should be minimal and mild. The most common side effects are related to extra fat being passed out through the stools – the more fat the more side effects.

• Crampy abdominal pain.
• Oily stools.
• Diarrhoea.
• Stool leaking.
• Urgent need to go to the toilet.
• Offensive wind.

Eating very little fat at mealtimes helps to minimise any side effects. Headaches and increased anxiety have also been
reported.

For full details of the potential side effects of Xenical, please read the patient information leaflet that comes with your medication before you start to use it.

If you develop any side effects that you are concerned about when taking this medication, stop the treatment and speak with a doctor for advice.

• When completing the questionnaire, please ensure you let us know exactly what medications you are taking (prescribed and over the counter) to enable us to prescribe safely and avoid potential drug interactions.
• There are no significant drug reactions reported with Xenical. However, it can affect the absorption of medications, and therefore the effectiveness of some medications. This is especially important for medications that work within a narrow therapeutic range such as lithium, warfarin, ciclosproin, antiepileptics and antiretrovirals. In these cases, you should speak with your local GP or specialist about starting this medication.
• The absorption of thyroid medication may be affected by Xenical, so it is best to take these tablets at different times and speak with a doctor if you feel your thyroid symptoms are not as well controlled.
• If you are using the oral contraceptive pill it cannot be relied upon for contraceptive cover if taking Xenical and you should use additional or alternative contraception.

No, to successfully manage your weight with Xenical, you will use it in conjunction with a low-fat, balanced diet. You should also engage in regular exercise and limit alcohol intake. You can read more on this here.

Once you have stopped taking this medication, it is important to continue with these changes so that weight loss can be maintained.

If you do gain weight again after stopping this treatment, it may be appropriate to consider another course of xenical or other weight loss treatments, depending on your individual situation.

Weight loss is not recommended during pregnancy, even if you are overweight or obese. It is advised that there is minimal weight gain. Xenical is not considered safe during pregnancy or breastfeeding.
