If you’re looking to buy orlistat 120mg capsules online in the UK, it’s crucial to choose a provider that offers not only convenience but also safety, reliability, and clinical oversight. In 2025, with the growing popularity of online pharmacies, PostMyMeds continues to lead the way as the UK’s most trusted provider of weight loss medications, including generic Xenical (orlistat 120mg). With over 11,500 verified reviews and a near-perfect 4.9 rating on Trustpilot, PostMyMeds stands out as the best place to order orlistat online.
In this article, we’ll cover what orlistat is, how it works, who it’s for, and why PostMyMeds is the best choice in 2025.
What Is Orlistat 120mg and How Does It Work?
Orlistat 120mg is a prescription weight loss medication that works by blocking the absorption of fat in your digestive system. It belongs to a class of drugs known as lipase inhibitors. When taken with a meal containing fat, orlistat attaches to the enzymes (lipases) responsible for breaking down dietary fat, preventing up to 30% of that fat from being absorbed by the body.
Instead, the undigested fat passes through your digestive system and is expelled as waste. This process helps reduce calorie intake, supporting gradual and sustainable weight loss when combined with a healthy diet and regular physical activity.
Orlistat is the active ingredient in Xenical, but the generic version is just as effective and far more cost-effective—especially when purchased from a trusted online provider like PostMyMeds.
Who Can Use Orlistat?
Orlistat is suitable for adults aged 18 and over with:
- A BMI of 30 or higher
- A BMI of 28 or higher and additional weight-related conditions such as high blood pressure, type 2 diabetes, or high cholesterol
Patients must be committed to a calorie-controlled, low-fat diet and regular physical activity. Orlistat is not a miracle pill—it’s a clinically proven support tool for people serious about achieving long-term weight loss.
A key benefit of using PostMyMeds is their online medical assessment process. You don’t need to visit your GP. Instead, you complete a quick, confidential consultation reviewed by a licensed prescriber, ensuring orlistat is suitable for you.

How to Take Orlistat 120mg for Best Results
- Dosage: One 120mg capsule with each main meal (up to three per day)
- Timing: Take during, just before, or up to one hour after eating
- Diet: Meals should contain a small amount of fat; avoid high-fat meals to minimise side effects
- Hydration: Drink plenty of water throughout the day
Do not take orlistat if you’re eating a meal that contains no fat. If you miss a dose, do not double up. Consistency is key. Results typically appear within the first few weeks of treatment, and you should see at least 5% weight loss within 12 weeks.
How Long Does Orlistat Take to Work?
Many users start noticing changes within two to four weeks of beginning treatment. Clinical guidelines recommend evaluating progress at the 12-week mark. If you’ve lost at least 5% of your initial body weight, it may be suitable to continue orlistat under the guidance of a healthcare professional.
Regular use, combined with a balanced diet and exercise plan, is the best way to ensure long-term success.
Foods to Eat and Avoid While Taking Orlistat
Eat:
- Grilled chicken, lean meats
- Steamed vegetables
- Whole grains and legumes
- Low-fat dairy options
- Fresh fruit
Avoid:
- Fried foods
- Creamy sauces
- Cheese-heavy meals
- Fatty cuts of meat
- Sugary snacks and processed foods
Keeping each meal to no more than 30% fat content will help reduce the risk of gastrointestinal side effects.
Orlistat Side Effects: What to Expect
Common side effects include:
- Oily or fatty stools
- Increased urgency to go to the toilet
- Flatulence with discharge
- Mild abdominal discomfort
- Headaches
These are usually temporary and can be managed by reducing the fat content in your meals.
Rare but serious side effects include:
- Allergic reactions (rash, swelling, difficulty breathing)
- Liver problems (yellowing of skin/eyes)
- Kidney stones (especially in those with pre-existing kidney disease)
Stop taking orlistat and consult your doctor immediately if you experience any severe or unusual symptoms.
