Q: How much do I take a day?
The dose is a maximum of 3 a day.
Q: When should I take alli?
Take just before or during a meal, or up to one hour after the meal. If you are eating a meal that does not contain fat, do not take alli.
Q: If I eat a high fat meal should I take two alli?
No. You should never take more than the recommended dose of a medicine. Take one at mealtimes, three times a day. This usually means one alli at breakfast, lunch and dinner. Make every effort to avoid high-fat meals while on the alli programme. Taking alli with a meal containing more fat than your recommended target, may increase the chances of diet-related treatment effects.
Q: Can I take two alli with a meal to help me lose weight more quickly?

Q: What if I miss taking alli?
If you forget to take alli and more than an hour has passed since your meal, do not take another one. Just wait until your next meal and take alli then. Never take two alli at the same time.
Q: What if I eat more than three meals a day. Should I still take alli with each meal?
No, take no more than 3 per day. Just choose 3 meals that contain fat and take alli with those meals.
If you are eating more than 3 meals a day, you may need to check you are not exceeding your daily calorie target.
Q: If alli only works on the fat in my food, how do I lose the fat in my body?
As you eat fewer calories on a reduced calorie, lower-fat diet - and use alli to prevent absorption of some of the fat you eat - your body will automatically tap into its fat stores and use them for the energy it needs. This leads to weight loss as your body burns its fat.
Q: What happens if alli is taken with a fat-free meal?
Nothing, because there's no fat for alli to work on. Don't take alli if you're going to eat a meal that doesn't contain fat.
Q: How long does alli remain in my body?
Since the time it takes people to digest food varies, the active ingredient in alli can remain in your body for up to 48 to 72 hours, mainly because the time taken for food to pass through the digestive system varies from person to person. However, it only affects the fat absorption of meals that are eaten within a short time of taking alli. Only a very small amount of orlistat is absorbed into the bloodstream.
Q: Why should I take a multivitamin when I'm taking alli?
You should take a multivitamin every day because alli can lower the levels of some fat-soluable vitamins absorbed by your body. The multivitamins should contain vitamins A, D, E and K. You should take the multivitamin at bedtime, when you will not be taking an alli diet pill, to help ensure that the vitamins are absorbed.
Q: Why should I take the multivitamin at bedtime?
If you take the multivitamin with a meal, at the same time that you take alli, then this could cause some of those vitamins to be lost. So it's best to take the multivitamin at a time when you won't be taking alli, such as bedtime.
Q: What sizes do the alli packs come in?
alli is available in packs of 42, 84 and 120.
