## What is Orlistat?

Orlistat is the most widely available dedicated weight-loss medicine in Nigeria. Best known by the brand Xenical, and locally as Reeshape and Orlifit, it works in a completely different way from every other slimming product: it acts only in the gut, blocking the enzyme (lipase) that digests fat, so roughly a third of the fat you eat passes through undigested instead of being absorbed. Because it barely enters the bloodstream, it does not suppress appetite or 'burn fat' — it simply stops some dietary fat from being taken in.

Used properly — one capsule with each main meal, alongside a reduced-calorie, lower-fat diet — orlistat produces modest but real weight loss: typically a few extra kilograms over six months to a year compared with diet alone, with the best results in people who also change what they eat. It is much less powerful than the newer injectable GLP-1 medicines (semaglutide/Ozempic, tirzepatide/Mounjaro), but it is oral, far cheaper, and has decades of safety history. Its famous drawback is the side effects when you eat fatty food: oily stools, urgency, and wind with oily discharge — which is really the drug 'showing you' the fat you ate.

A hard word of caution about Nigeria's weight-loss market: it is flooded with 'slimming teas', 'flat tummy' coffees, herbal capsules, and social-media products that are unregistered, and some have been found to secretly contain dangerous pharmaceutical ingredients such as sibutramine — a banned appetite suppressant linked to heart attacks and strokes. Orlistat, by contrast, is a real, NAFDAC-registrable medicine with known effects and limits. If you choose medication for weight loss, use a registered product from a licensed pharmacy — and be deeply suspicious of anything sold as a 'natural' rapid-slimming miracle.

## What is Orlistat used for?

- Weight loss in adults with obesity (BMI 30+), together with a reduced-calorie, lower-fat diet
- Weight loss in overweight adults (BMI 28+) who have risk factors such as diabetes, hypertension, or high cholesterol
- Helping to keep weight off after successful dieting
- Modestly improving blood sugar, blood pressure, and cholesterol as weight falls

## Dosage

Always follow a doctor's or pharmacist's instructions; this is general reference information.

- Adults: The standard dose is 120mg (one capsule) three times a day, taken with — or up to one hour after — each main meal that contains fat. If you skip a meal, or the meal has no fat, skip that dose. It only works alongside a reduced-calorie diet with roughly 30% of calories from fat, spread across the day; a very fatty meal will produce unpleasant oily side effects. A lower 60mg strength exists in some markets for over-the-counter use.
- Children: Not recommended for children; specialist use only in adolescents in some countries.
- Elderly: Can be used; no specific dose change, but overall health and nutrition should be considered.

Give it a fair trial with the diet: if you have not lost about 5% of your body weight after 12 weeks, it is usually stopped, because it is unlikely to work well for you. Take a multivitamin at bedtime (at least 2 hours away from orlistat) — the drug reduces absorption of fat-soluble vitamins A, D, E, and K. Expect results in months, not days: any product promising rapid, effortless weight loss is not being honest with you. Orlistat works best as one part of a plan — food changes, activity, and realistic goals.

## Side effects

Common: Oily or fatty stools, and oily spotting or discharge (worse after fatty meals); Urgency to open the bowels, more frequent stools, and wind; Stomach pain or discomfort; Headache; These gut effects are the fat you ate passing through — they lessen a lot on a lower-fat diet.

Serious (seek medical help immediately): Signs of liver problems (rare): yellowing of the eyes or skin, dark urine, severe stomach pain, unusual tiredness; Severe allergic reaction: swelling of the face or throat, difficulty breathing; Kidney stones or, rarely, kidney injury (oxalate-related) in susceptible people; Severe or persistent diarrhoea leading to dehydration.

When to see a doctor: See a doctor for yellowing of the eyes or skin, dark urine, or severe abdominal pain (possible liver problems), for severe persistent diarrhoea, or for any allergic reaction. Also seek advice if you take medicines whose absorption could be affected — such as thyroid hormone, epilepsy medicines, warfarin, or HIV treatment — so doses and timing can be managed safely.

## Warnings

Do not take if: Do not use in pregnancy or while breastfeeding; Do not use in chronic malabsorption syndrome (a condition where the gut already absorbs food poorly); Do not use in cholestasis (blocked bile flow); Not a treatment for being mildly overweight without risk factors, and not for people with eating disorders; Do not use if you are allergic to orlistat.

Interactions: Levothyroxine (thyroid hormone) — absorption is reduced; separate doses by at least 4 hours and monitor; Warfarin — vitamin K absorption changes can affect INR; extra monitoring is needed; Ciclosporin — levels can fall dangerously; the combination is generally avoided; Epilepsy medicines — absorption may fall, risking seizures; monitor closely; Some HIV antiretrovirals — orlistat may reduce their absorption and effectiveness; discuss with your doctor before combining; Fat-soluble vitamins (A, D, E, K) and the contraceptive pill during severe diarrhoea — take a bedtime multivitamin, and use extra contraceptive precautions if severe diarrhoea occurs.

Pregnancy & breastfeeding: Do not use orlistat during pregnancy — weight loss is not appropriate in pregnancy, and dieting plus reduced vitamin absorption can harm the baby. It should also be avoided while breastfeeding. If you become pregnant while taking it, stop and speak to a health worker.

## How to verify it is genuine

1. Buy orlistat from a licensed pharmacy, ideally after discussing it with a pharmacist or doctor
2. Check the NAFDAC registration number on the pack and verify it on the NAFDAC Green Book or app — for example Reeshape (Adler Products) is A4-7211
3. Check the expiry date and that the packaging is sealed and untampered
4. For Xenical, be especially careful: premium imported weight-loss brands are prime counterfeit targets — check the manufacturer branding, batch number, and buy only from reputable pharmacies
5. Avoid 'slimming teas', 'flat tummy' products, and social-media weight-loss capsules entirely — many are unregistered, and some have been found to contain hidden, banned drugs such as sibutramine
6. Genuine capsules should be uniform; discard any that look irregular

## FAQs

### Does orlistat really work for weight loss?

Yes — modestly, and only together with a diet. Orlistat blocks about a third of the fat in your food from being absorbed, and in studies people taking it with a reduced-calorie diet lose a few kilograms more over 6-12 months than with diet alone; many achieve 5-10% of their body weight overall. It is genuinely effective but not dramatic: it will not melt weight off while you eat as before — in fact, eating fatty food on orlistat quickly punishes you with oily stools. The practical test: if you haven't lost about 5% of your weight after 12 weeks on it, it's not the right tool for you and is usually stopped.

### What is the difference between orlistat and Ozempic (semaglutide)?

They work completely differently. Orlistat acts only in your gut, blocking fat absorption — it doesn't touch your appetite. Semaglutide (Ozempic) and tirzepatide (Mounjaro) are injectable GLP-1 medicines that act on appetite and fullness signals, and they produce much larger weight loss (often 10-20% of body weight) — but they cost hundreds of thousands of naira monthly in Nigeria, need weekly injections, and genuine supply is scarce. Orlistat is oral, far cheaper, and widely available, with decades of safety history. For many Nigerians it is the realistic starting medicine, with GLP-1s as the powerful (expensive) option for those who need and can sustain them.

### What are the side effects of orlistat — and are the 'oily stool' stories true?

True, and worth understanding rather than fearing. Because orlistat stops fat being absorbed, that fat exits with your stool — so fatty meals cause oily, loose stools, urgency, wind with oily spotting, and stained underwear. It is essentially instant feedback on how much fat you just ate: people who stick to a lower-fat diet get few or no problems. The effects fade as you adjust your diet — which is partly how the drug trains eating habits. Separately, take a multivitamin at bedtime, since orlistat reduces absorption of vitamins A, D, E, and K. Serious side effects (liver problems, kidney stones) are rare.
