Alli (orlistat) Capsules is used for weight loss in overweight adults, 18 years and older, when used along with a reduced-calorie and low-fat diet. It works by blocking absorption of 25% of the fat in a meal. Common side effects include changes in your bowel function because of the unabsorbed fat. Fatty/oily stool, oily spotting, intestinal gas with discharge, a feeling of needing to have a bowel movement right away, increased number of bowel movements, or poor bowel control may occur. These side effects may worsen if you eat more fat than you should.

The recommended dose of Alli for overweight adults 18 years and older is 1 60-mg capsule with each meal containing fat, not to exceed 3 capsules daily. Use with a reduced-calorie, low-fat diet. Alli may interact with warfarin, cyclosporine and medicines for thyroid disease. Tell your doctor all prescription and over-the-counter medications and supplements you use. Alli is not recommended for use during pregnancy. It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.

(Adverse Reactions)

SIDE EFFECTS

Some people on alli™ (orlistat 60 mg) will experience GI side effects, which is expected since alli (orlistat 60 mg) works by inhibiting about 25% of dietary fat. alli (orlistat 60 mg) is half the strength of prescription Xenical® (orlistat 120 mg), and, as a result, has fewer GI events overall than Xenical®. In clinical trials, subjects on 120 mg withdrew due to GI adverse events at a rate of 5.4%-and at 60 mg it was only 3.2%.

The main treatment effect occurs when an individual eats a meal with too much fat while taking alli (orlistat 60 mg) . Treatment effects may include:

  • Loose or more frequent stools that may be hard to control
  • An urgent need to go to the bathroom
  • Gas with oily spotting
  • While excess fat that is excreted is not harmful, patients could be distressed by the experience. Treatment effects can be lessened if an individual sticks with reduced-calorie, low-fat meals that average 15 grams of fat per meal (or 30% fat or less). Diets may vary from 1,200 calories to 1,800 calories per day, so 15 grams is an average. Individuals need to be aware of hidden fat in food, so that they can lower the chance of having treatment effects.

Not all individuals will experience treatment effects, but those that do can reduce the likelihood of these effects by taking alli (orlistat 60 mg) as directed and sticking with a reduced-calorie, low-fat diet. The alli (orlistat 60 mg) starter pack includes portable reference guides and online support at myalli (orlistat 60 mg) .com to help patients follow the program accurately. Some patients may experience treatment effects as they begin therapy until they learn to adjust their diet.
