About Alli
-
-
alli is an over-the-counter weight loss treatment containing the active ingredient orlistat. Each alli capsule contains 60 mg of orlistat and should be taken with meals containing fat, alongside a diet and exercise plan.
You’ll need to check your body mass index (BMI) before taking alli weight loss pills, as it must be 28 or above.
Is alli the same as orlistat?
alli and generic orlistat tablets contain the same active ingredient (orlistat), but alli is sold under a branded name. Although orlistat requires a prescription, you can buy alli over the counter as each tablet only contains 60 mg of orlistat, which is a lower dose than generic orlistat tablets. Even though you don’t need a doctor’s prescription, a pharmacist or doctor will still check your medical history and BMI before prescribing it.

Studies have found alli to be an effective weight loss treatment, helping people to lose weight 50% faster than with dieting alone. It can also help you lose up to 5% of your initial body weight. For alli to be most effective, you need to take it correctly and follow a diet and exercise plan.
This study gave half of the participants alli tablets and the other half a placebo. All participants followed a low-calorie and low-fat diet. Participants who took the placebo lost around 3.11 kg in 6 months, while those taking alli weight loss pills lost 5.20 kg.
The study also looked at the percentage of participants who lost at least 5% of their initial body weight. In the placebo group, 30.9% lost at least 5%, while 54.6% of those taking alli capsules lost at least 5% of their start weight.
The patient information leaflet also states that ‘for every 2 kg (4 lb) you lose from dieting alone, alli can help you lose 1 kg (2 lb) more’.

alli pills work by stopping your body from absorbing fats from meals, which instead leave your body as waste to help you lose weight. The active ingredient achieves this because it is a type of lipase inhibitor. Lipase is an enzyme made in the mouth, stomach, and pancreas. It’s used to break down fat from food, which is then absorbed by your intestines.
When you take alli capsules, they stop lipase from activating. This means some of the fat from your meal will not be absorbed. Instead, around a third of the fat will leave your body as waste through bowel movements (poop).
How long does alli stay in your system?
alli stays in your digestive system for around 6 hours. It usually takes 3 to 5 days for alli to fully leave your system. It will become less effective during this time, which means you need to take it with every meal containing fat for it to reach full effect.
How fast does alli work?
alli starts to work within a few hours, but it may take a few weeks for you to see weight loss results.

alli is currently rated as 6 out of 10, according to Drugs.com, with 114 reviews. Some of the highest-rated reviews talk about the benefits of using alli while going through menopause, which can sometimes cause weight changes.
In these reviews, the most common side effects reported are loose stools and wind. Some reviewers also recommend eating less fat to reduce unwanted side effects. Most people appear to have had a positive experience while taking alli tablets.
-
-
alli diet pills should be taken with meals that contain fat, up to 3 times per day. You can take them before, during, or up to an hour after your meal. Swallow your alli tablet whole and with a glass of water. Never break or crush an alli tablet.
After you’ve taken alli for 12 weeks, you should speak to a doctor or pharmacist if you’ve not lost any weight. You may need to stop taking it. You also shouldn’t use alli for longer than 6 months in total.
How many alli capsules should I take per day?
You can take alli up to 3 times a day, with 1 pill being taken per meal containing fat. Just because you can take alli up to 3 times a day doesn’t mean you have to. If you only eat 1 or 2 meals containing fat, then you won’t need to take 3 tablets.
What happens if you take 2 alli capsules at once?
If you take more than the maximum dose in a day, speak to a doctor straight away. You should never take more than 1 alli pill with each meal, and never more than 3 in a day. Taking 2 alli pills at once will increase the risk of side effects.
What is the best time to take alli?
You can take alli before, during, or after your meal.

- changes to your stools, such as oily, fatty, or soft
Common alli side effects include:

“As long as you meet the requirements to take alli, it’s a safe and suitable treatment option. If you get alli at a pharmacy, the pharmacist will ask you a few questions first to make sure it won’t react with any other medications you take or any health conditions you have. You can also speak to your doctor if you want further advice on taking alli tablets or losing weight in general.” – Dr Babak Ashrafi, Clinical Lead for Service Expansion at ZAVA.

alli may cause unpleasant side effects or could react with certain medications. It could also make some medical conditions worse. You should speak to a pharmacist or doctor before taking alli tablets if you have:
- diabetes, as a doctor may need to adjust your diabetic medication doses
- kidney disease, as it can increase your risk of kidney stones
If you take an oral contraceptive pill and get diarrhoea or loose stools, it could become less effective, which will increase your chances of becoming pregnant. If you get severe diarrhoea while taking alli, you should use another method of contraception when having sex.
It’s also recommended to take a multivitamin every day while using alli tablets, as it can lower the levels of certain vitamins in your body. This includes vitamins A, D, E, and K. To make sure the vitamins are absorbed, take them at bedtime, at least a few hours after taking your last alli dose.
You should also speak to a doctor or pharmacist before using alli if you take the following medications:
- amiodarone, for heart rhythm problems
- acarbose, an anti-diabetic drug
- the thyroid medicine levothyroxine
- any medicine for epilepsy
- medicines to treat HIV
- any treatments for mental health disorders
- high blood pressure medication
- high cholesterol medication
Is alli safe to take long-term?
alli should be taken for a maximum of 6 months. If you’ve not reached your weight loss goals after this time, speak to your doctor. They may be able to recommend a different weight loss treatment plan that’s more suitable.

If you’re looking for an alli alternative, there are plenty of other weight loss medications available. These include other medications containing orlistat, such as Xenical and generic orlistat. Although alli is the only over-the-counter treatment, you can be prescribed other weight loss pills or try a weight loss injection.
alli vs Xenical: Is alli as good as Xenical?
alli is not necessarily better or worse than Xenical, but Xenical may be more effective as it’s taken at a higher dose. alli and Xenical both contain orlistat, but Xenical is a prescription-only treatment. This is because it contains 120 mg of orlistat, rather than the 60mg that are contained within alli capsules.
Clinical trials for alli and Xenical are difficult to compare, as they aren’t carried out over the same number of weeks. But the results from Xenical trials seem to have a higher rate of weight loss than alli, which is likely due to the fact that it’s a higher dose medication:
alli (orlistat 60 mg) Xenical (orlistat 120 mg) Patients that lost at least 5% of their body weight 54.6% after 6 months
60% after 12 weeks
-
-
Although alli and Xenical contain the same active ingredient, you shouldn’t take 2 alli pills to make the dose for 1 Xenical tablet. Xenical is a prescription-only medication and taking 2 alli pills at once, or more than 3 in a day, is classed as an overdose.
To take 120 mg of orlistat with each meal, you need a prescription from a doctor who can make sure that this dose is suitable for you. If you’d rather take Xenical than alli, we also stock this.
Is alli the same as orlistat?
No, while alli is similar to orlistat generic tablets, there are a few differences when comparing them.
alli tablets don’t require a prescription and only contain 60 mg of orlistat. Generic orlistat requires a prescription, and each capsule contains 120 mg of orlistat.

Aside from Xenical and orlistat, the other weight loss pill on the market is Mysimba. Mysimba tablets work on the part of your brain responsible for appetite to reduce your hunger levels so you feel full after less food, which makes it easier to eat less. Mysimba tablets contain the active ingredients naltrexone hydrochloride and bupropion hydrochloride.
You can also get weight loss injections, but you’ll need a BMI over 30, or a BMI over 28 and have or be at risk of a weight-related medical condition, such as diabetes.
Saxenda, Wegovy, and Mounjaro are the 3 injections currently approved for weight loss in the UK. They all mimic hormones that can help regulate appetite and hunger levels, as well as blood sugar.
Wegovy is a relatively new weight loss injection that’s become very popular. It was adapted from a type 2 diabetes medication called Ozempic. It is a great alternative if you’d rather take a once-weekly injection than take daily alli pills. Wegovy sends signals to your brain that you’ve eaten, as it mimics a hormone called glucagon-like peptide 1 (GLP-1), making it easier to reduce your calorie intake and snacking between meals.
Saxenda contains the active ingredient liraglutide and is taken once a day. You can switch from Saxenda to Wegovy if you’re currently using Saxenda, as it’s currently long-term out of stock.
Mounjaro is the newest weight loss injection and contains tirzepatide. It was also a type 2 diabetes medication but is now approved for weight loss as well. It makes you feel less hungry by affecting the parts of your brain responsible for appetite control, and delays the emptying of your stomach so you can feel fuller for longer. Mounjaro mimics 2 hormones, rather than Wegovy and Saxenda which only mimic 1.

Frequently asked questions
Does alli work without exercise?
alli will work without exercising, although you won’t get the best results from taking it. You can only take alli for 6 months at a time, so you should take alli alongside a diet and exercise regime for maximum effectiveness. This will also reduce the chances of putting weight back on when you stop taking it.
Can I take alli if I'm not overweight?
No, you can only take alli if your BMI is 28 or above, which is classed as overweight. It’s not safe to take weight loss medications if you are at a healthy weight on the BMI scale, as this could cause you to become underweight.
Do you gain weight after stopping alli?
You’ll only gain weight after stopping alli if you go back to a high calorie diet. Fad diets only work for a little while, and if you go back to the way you used to eat before, your weight is likely to increase again. That's why patients are advised to follow a healthy diet and exercise plan, as this will help to keep the weight off even after treatment is stopped.
Does alli help lose belly fat?
alli will help you lose weight, which may result in less belly fat. However, weight loss can not be targeted to a specific part of the body, so it may not happen right away.
How fast does alli make you poop?
Some people who take alli can get sudden urges to go to the toilet, while others go normally. You may notice that your stools are looser or oily. This is normal and is the unabsorbed fat leaving your body.
If you find that alli is making you pass stools quickly after eating, or a lot more than usual, you can try reducing the amount of fat you eat at each meal, which should reduce this.
What should I eat when taking alli?
For the best weight loss results while taking alli, you should eat a balanced, healthy diet. This includes plenty of fruit and vegetables, proteins, and a small amount of healthy fats. You should also avoid or limit sugary, high-fat, high-processed, and greasy foods. High-calorie drinks, such as fizzy drinks or alcohol should also be limited or avoided.
Is alli for men?
alli can be taken by men and women, you just need to be over 18 and have a BMI of 28 or over.
Is there a shortage of alli?
We are not aware of a shortage of alli at the moment. If alli is out of stock somewhere, this may just be because the pharmacy or retailer has not restocked it yet.
Is alli hard on the liver?
alli is not hard on the liver, but it can increase your risk of hepatitis, which is an inflammation of the liver. If you’re worried about these side effects, speak to your doctor.
Can you take alli and Saxenda together?
No, you cannot take alli and Saxenda together. You shouldn’t take any 2 weight loss medications together, as this will increase your risk of side effects and may make you lose weight too quickly, which can be dangerous.
