What is Xenical?
Xenical is used as a weight loss treatment in people with a BMI of 30 or more, together with a healthy, balanced diet and regular exercise, as part of an overall weight-loss plan.
Xenical prevents the absorption of some of the fat you eat. When taking it, you need to eat a well-balanced diet that is high in fruit and vegetables and with less than 30% of calories from fat. More fat in your diet will increase the side effects of this medicine. Your daily intake of fat, carbohydrates and protein should be spread out over 3 main meals.
In New Zealand, Xenical is available as capsules (120mg). Xenical can be purchased from pharmacies without a prescription. A pharmacist needs to ask you questions to make sure it is the best option for you and needs to record your name and address.
How to take Xenical
- The usual dose of Xenical is 1 capsule up to 3 times a day.
- Take Xenical with liquids while you are having a main meal or up to 1 hour afterwards.
- If you miss a meal or eat a meal that contains no fat, you should skip that dose of Xenical.
- Because Xenical may decrease the amount of some vitamins that your body absorbs from food, you need to take a multivitamin supplement once a day.
- Take the vitamin supplement at least 2 hours before or after taking Xenical.
- You may also take your multivitamin supplement at bedtime.
Precautions – before taking Xenical
- Do you have chronic malabsorption syndrome?
- Do you have cholestasis or problems with your gall bladder?
- Do you have kidney or liver problems?
- Are you pregnant or breastfeeding?
If so, it’s important to tell your doctor or pharmacist before you start Xenical. Sometimes a medicine isn’t suitable for a person with certain conditions, or it can only be used with extra care.
Like all medicines, Xenical can cause side effects, although not everyone gets them. Common side effects are fatty or oily stools, wind, stomach cramps and bloating. These usually occur if your diet is too high in fat.
