  • Buy Alli Weight Loss Capsules 
    Alli Weight Loss Capsules are clinically proven to help you lose more weight than dieting alone. These effective, easy-to-take capsules stop about a quarter of the fat in your meals from being absorbed. Alli can boost your weight loss efforts, too, meaning that for every 2lb you lose, they can help you to lose an extra 1lb.

    Your BMI (body mass index) is a measure that uses both your height and weight to see if your weight is healthy. Alli Weight Loss Capsules are designed for those who have a BMI of 28 or over and are considered overweight. If you’re unsure about your BMI, the NHS has a BMI calculator that can do the hard work for you.

    How Alli Weight Loss Capsules work
    The active ingredient in Alli Weight Loss Capsules is orlistat, a drug designed to combat obesity by targeting the fat in your digestive system. It stops about a quarter of the fat in your meals from being absorbed and passes out of the body in your stools. 

    Alli must be used in combination with a reduced-calorie, low-fat diet. The capsules will assist your efforts by helping you lose more weight compared to dieting alone. 

    Directions
    Always take Alli Weight Loss Capsules exactly as described in the patient information leaflet or as your Weight Medics clinician has told you. You should take Alli Weight Loss Capsules with a reduced-calorie, low-fat diet and exercise program until you reach your weight loss goal.

    For adults aged 18 and over, take 1 capsule with every meal that contains fat. Do not take more than 3 capsules per day. While taking this product, taking a multivitamin once a day at bedtime is recommended. This is because the active ingredient, orlistat, reduces the absorption of some vitamins. 

    Consuming too much fat makes you more likely to experience side effects such as diarrhoea. For this reason, do not exceed the amount of allowed calories and fat content in your meals and snacks. Your calorie target will depend on your gender, activity levels, and weight. For more information on calorie targets, refer to the information leaflet provided.

    Side effects
    Like all medicines, Alli Weight Loss Capsules may cause side effects in some people, but these won’t affect everybody. Side effects may include:

    • Gas with oily spotting
    • Loose stools
    • More frequent stools that may be hard to control
    • For more information on potential side effects, refer to the patient information leaflet. If you experience any side effects, including any not included in the patient information leaflet, you can report them using the MHRA Yellow Card Scheme.

    Serious side effects
    Seek emergency medical attention if you notice any signs of a severe allergic reaction, symptoms of which include swelling of the face and throat, skin rash, breathing difficulties and/or loss of consciousness. 

    Warnings
    Alli Weight Loss Capsules may be unsuitable for certain people. Do not take these capsules if you are allergic to orlistat or any of the other listed ingredients. Do not take these capsules if you:

    • Have had an organ transplant
    • Are taking cyclosporine
    • Have been diagnosed with a problem absorbing food
    • Are not overweight

     Talk to your doctor or Weight Medics clinician before taking these capsules if you:

    • Are taking any other medication
    • Have gallbladder problems
    • Have kidney stones
    • Have pancreatitis

     Although Alli Weight Loss Capsules won’t directly impact the effectiveness of the contraceptive pill, you may experience diarrhoea while taking it, which can reduce the pill’s effectiveness. If this happens to you, you should use an extra method of contraception until the diarrhoea has passed.

Mounjaro for maintenance

I have been taking Mounjaro for maintenance purposes. I was originally two stones heavier. Weight Medics are totally professional and the process of reordering a prescription is straight forward and hassle free. I was advised that because of my height and age to try and not go much below 60 kilos and I have tried to follow this guidance as closely as possible.
