Choose Your Orlistat Pack Size: 2, 4, 8 or 12 Weeks

When Does Orlistat Start Working?

Orlistat begins blocking fat absorption within hours of taking your first capsule. You may notice the medication working within 24-48 hours, typically through changes in bowel movements as unabsorbed fat passes through your system. This immediate action helps you choose the right pack size based on your treatment goals and budget.

2-Week Starter Packs: Perfect for First-Time Users

Our 2-week supplies (42 capsules) are ideal if you're new to orlistat and want to assess how your body responds. Generic orlistat 2-week packs cost £16.89 (£15.20 with EDM10), whilst Xenical costs £21.50 (£19.35 with EDM10). This short supply lets you monitor side effects and adjust your diet before committing to longer treatment courses.

4-Week Supplies: The Popular Choice

Four-week packs (84 capsules) offer excellent value whilst providing enough medication to establish a routine. Generic orlistat costs £32.99 (£29.69 with EDM10), Xenical costs £42.99 (£38.69 with EDM10), and Alli 60mg costs £28.99 (£26.09 with EDM10). This duration allows you to experience orlistat's full effects alongside your reduced-calorie, lower-fat diet.

8-Week Treatment Courses

Eight-week supplies (168 capsules) provide substantial savings and continuity of treatment. Generic orlistat costs £63.99 (£57.59 with EDM10), saving you money compared to buying multiple shorter packs. Xenical 8-week supplies cost £86.99 (£78.29 with EDM10), whilst Alli costs £54.99 (£49.49 with EDM10). This duration suits established users who understand how orlistat works with their lifestyle.

12-Week Maximum Savings

Our largest packs (252 capsules) offer the best value for long-term weight management. Generic orlistat 12-week supplies cost £95.99 (£86.39 with EDM10), representing significant savings. Xenical costs £128.99 (£116.09 with EDM10), and Alli costs £129.99 (£116.99 with EDM10). These packs suit committed users following structured weight management programmes.

Comparing Your Options

Generic orlistat 120mg provides identical clinical effects to branded Xenical at lower cost, whilst Alli 60mg offers half the dose for those preferring lower-strength treatment. All products work by inhibiting lipase enzymes to block approximately one third of dietary fat absorption. Choose your preferred option based on budget, brand preference, and dosing requirements.
