Alli is a 60mg over-the-counter version of the prescription weight loss drug orlistat. It is indicated for use by overweight and obese adults who are otherwise healthy. With a doctor's approval, people with pre-existing health conditions, such as high blood pressure or diabetes, may take Alli. The success of the Alli program depends on your willingness and ability to follow the entire program.
Function
Alli weight loss pills block the absorption of up to 25 percent of fat in the diet. Alli works in digestive tract by disabling lipase, which is the enzyme that breaks down fats in the intestines. Since the fat isn't broken down, it continues to travel through the digestive tract and is eliminated in the stool.
Components
Alli weight loss pills are part of a weight loss program that includes low-fat meals and daily exercise. According to MyAlli, meals consumed while taking Alli should contain no more than 15g of fat per meal. A balanced diet that includes all major food groups, including grains, fruits, vegetables, protein and milk, is necessary when taking Alli. At least 30 minutes of moderate intensity exercise daily is recommended.
Time Frame
One Alli pill is taken with each meal, with a maximum of three pills per day. The pill must be taken within an hour---either before or after---a meal. Results from following the Alli program are sometimes noticed as soon as two weeks after starting Alli. MayoClinic.com notes that most of weight loss that occurs as a result of using Alli occurs in the first six months. During the first year of treatment, Alli may help you to lose an average of 3 to 5 lbs in addition to the average 8 lbs of monthly weight loss with only diet and exercise that most people experience.
Side Effects
Treatment effects that may occur when using Alli include frequent bouts of diarrhea, inability to control bowel movements, oily anal discharge, nausea and vomiting. These treatment effects can be minimized by eating no more than 15g of fat per meal as long as you are taking Alli.
Warning
Some people may have an allergic reaction to Alli, which is a medical emergency and necessitates a trip to the emergency room. Signs of an allergic reaction include facial or oral swelling and hives. Liver damage is also possible when taking Alli. Jaundice, which usually causes yellowing of the skin and eyes is possible. Liver injury is also possible, according to the Food and Drug Administration. Nausea, fatigue, weakness, vomiting, abdominal pain, light colored stool and fever are signs of liver injury. Pancreatitis, which may cause rapid heart beat, upper abdominal pain that goes toward the back and vomiting, is also possible. Symptoms of liver damage and pancreatitis should be evaluated as soon as possible by a doctor.
Considerations
Since Alli inhibits the absorption of fats, fat-soluble vitamins in the diet may not be properly absorbed. Fat soluble vitamins include Vitamins A, D and E. Because of this risk, taking a multivitamin is recommended by MayoClinic.com. However, the multivitamin shouldn't be taken with a meal because of these absorption issues. Instead, take the multivitamin immediately before bed.
