About Alli

What is Alli Weight Loss?
Alli is a licensed weight loss aid for people who are overweight and have a body mass index (BMI) of 28 or above. It targets fat in your digestive system, stopping it from being absorbed by your body. It is designed to help you to lose more weight compared to dieting alone. The active ingredient in this medicine is orlistat 60mg.
Alli Weight Loss and Alcohol
There is no direct interaction between Alli and alcohol, however alcohol is high in calories and can worsen gastrointestinal side effects. This can be counterproductive and undermine your weight loss efforts therefore it’s best to limit or stop alcohol consumption whilst using this treatment.

- Orlistat capsules contain the prescription-strength 120 mg, recommended for people with a BMI of 30 or higher
- Alli weight loss contains 60 mg and is available over the counter, recommended for adults with a BMI of 25 or higher

Alli Dosage Instructions
How to Take Alli Capsules
Alli tablets are most effective when used alongside a reduced calorie and low-fat diet. For your body to get used to this medicine, pick the date you’d like to start and begin your diet a few days beforehand, keeping a food record for reference.
Swallow one capsule with water, three times a day at breakfast, lunch and dinner. You can take it just before, during or up to one hour after meals.
You must not take Alli if you miss a meal, or the meal contains no fat because it does not work without fat.
Alli capsules should not be taken more than three times a day and for no longer than six months.

- You’re pregnant or breast-feeding
- You’re taking ciclosporin
- You’re taking warfarin or other blood thinning medicines

- Acarbose – anti-diabetic medicine used to treat type 2 diabetes mellitus
Vitamin levels absorbed by your body can be reduced whilst using this medicine therefore it is recommended that you take a multivitamin every day. It should contain vitamins A, D, E and K. Taking it just before bed, outside of when you take Alli, will help ensure proper absorption of the vitamins.
It’s important to disclose any medications you may be taking with your doctor before you use this treatment. Alli can impact the effectiveness of the following medicines:
- The oral contraceptive pill – may be less effective in cases of severe diarrhoea
- Amiodarone – used for heart rhythm issues
- Thyroid medicine (levothyroxine)
- Medicines for epilepsy
- Medicines to treat HIV
- Medicines for depression, anxiety or psychiatric disorders
- Medicines for high blood pressure
- Medicines for high cholesterol
Important note: Avoid taking Alli with a meal containing too much fat as this may increase your chance of getting diet-related treatment side effects.
Alli Weight Loss and Pregnancy/Breastfeeding
Alli is not recommended for women who are pregnant because of its potential to interfere with nutrient absorption. It works by blocking the absorption of fats which could potentially lead to a decreased absorption of fat-soluble vitamins crucial for both the mother and the developing fetus, such as vitamins A, D, E, and K. Studies on the use of Alli in pregnant women are also limited and therefore it is typically advised against use during pregnancy.
There is a lack of scientific research around the use of Alli whilst breastfeeding. Alli may interfere with the absorption of the vitamins which are critical for the baby’s growth and development, potentially affecting the quality of breast milk and baby’s health. There is also uncertainty surrounding the small amounts of the drug which could pass into breast milk and what effects that might have on the baby, therefore it is not typically recommended.
Frequently Asked Questions
The best weight loss pill is based on individual needs and preferences. The effectiveness and safety will vary depending on your health and weight loss goals. It’s important to choose a weight loss pill that has been scientifically studied for its effectiveness. There are several options for you to choose from:
Xenical 120 mg blocks the absorption of fat and is available on prescription. It contains the active ingredient orlistat.
Alli weight loss pills are available as a 60 mg lower dosage and can be bought over the counter
Orlistat is the generic version of both Alli and xenical and works best when used in conjunction with a low-calorie diet. You can find out more about orlistat results and what to expect on our blog.
Orlistat mainly works in the GI tract and only very small amounts (about 1%) of the drug are absorbed systemically so it has minimal impact on the rest of the body. It takes 1-2 hours for half of the small amount that enters the bloodstream to be eliminated. Most of the drug is excreted in the feces within 3-5 days.
Alli is clinically proven and was licensed in January 2009. It is available without a prescription under the supervision of a pharmacist. Alli is one of the few weight loss medications approved for use on the NHS for weight management. To see results, Alli should be used in combination with a reduced calorie, lower-fat diet. You should also try to be more physically active before you start taking the capsules because this is an important part of a weight loss programme.
Orlistat is considered safe when used as prescribed. Like with all medication, it does come with potential side effects and may not be suitable for everyone. It’s important to read the patient information leaflet and always take this medicine exactly as described or as your doctor or pharmacist has told you.

Product Review
These tablets work very quickly when taken at initial onset of my cluster migraine. I find if I leave and take when full migraine they take longer.
By Vicky (via TrustPilot)
When ever I have a horrid migraine start take one of these 50mg little miracles and starts to work with in 20-30 mins… highly recommend Sumatriptans as they actually work and are cheaper than the other brands 👍🏼
By Kitty (via TrustPilot)
I have suffered with migraines on and off for years which I used to take regular medication for. They have recently increased again due to peri menopause. These sumatriptan tablets prevent me having to take bucket loads of pain killers when a migraine strikes and keeps the nausea at a distance. Highly recommended.
By Lisa Goulding (via TrustPilot)
Helps with my occasional migraines. Wish I'd discovered them earlier. I usually take one the moment I suspect it coming. Sometimes I pair with ibuprofen , but it's usually very effective!
