Patient Reviews: How Alli (Orlistat) Has Made a Difference

What are Alli weight loss pills?
Alli is a brand of weight loss pill from GlaxoSmithKline (GSK). They are available over the counter. When taken alongside a healthy diet and regular exercise, Alli is clinically proven to help you shed those extra pounds and reach your ideal weight.
Alli is intended for overweight adults with a Body Mass Index (BMI) of 28 or higher. BMI is a method for determining whether an individual is overweight or has a healthy weight, based on their height. Alli can help you shed more weight than dieting alone.
After completing treatment with Alli, continue the changes you made to your diet and exercise regimen to prevent future weight gain.
You can buy Alli weight loss pills online from Prescription Doctor after a brief consultation with one of our qualified doctors.
If your order is approved by one of our doctors before 3pm on weekdays, our pharmacy can dispense and dispatch your diet pills via a fast and discreet next-day delivery.
Dieting advice should always be taken from a trusted and reliable source. We encourage you to consult your GP or a qualified dietician for personalised advice on dieting and exercise.
How do Alli weight loss pills work?
Alli contains a lipase inhibitor called orlistat.
Lipase is a pancreatic enzyme that digests dietary fats by breaking them into glycerol and fatty acids that can either be burned for energy production or stored in the body. The body struggles to metabolise excessive dietary fat and stores it, leading to obesity.
Orlistat prevents fat from being absorbed through the intestines. Fat that isn't absorbed exits the body through bowel movement.
When combined with a low-calorie, low-fat diet, orlistat can help you achieve weight loss.
How do I take Alli weight loss pills?
Alli (orlistat) capsules should be swallowed whole with water three times daily; just before, during, or up to an hour after eating a meal.
Take Alli with each main meal: breakfast, lunch, and dinner.
Swallow Alli capsules whole with a glass of water.
Do not crush or chew Alli capsules.
Do not take Alli for longer than 6 months.
Consult your doctor if you haven't lost weight after taking Alli for 12 weeks.
Information on the amount of fat you can consume while taking Alli, based on your height and weight, can be found in the patient information leaflet (PIL).
What should I do if I forget to take Alli when I should?
If you forget to take Alli when you should, take the missed dose as soon as possible if it's less than an hour since your last main meal. Skip the missed dose if an hour has already passed since your last meal, and continue with the prescribed dosage. Don't take more to make up for the missed dose.
What should I do if I take too much Alli?
If you take more than 3 Alli capsules in a day, consult the doctor as soon as possible.
Taking too much Alli will not help you lose weight any faster, but may increase your risk of side effects.
