Choose Your Ideal Orlistat Supply Length
Taking Orlistat with Antibiotics: What You Need to Know
When considering orlistat alongside antibiotic treatment, timing and medical supervision are essential. Orlistat works by blocking approximately one third of dietary fat absorption in the gut, which may affect how some medications are absorbed. Our qualified UK-licensed prescribers assess each case individually, reviewing your antibiotic type, treatment duration, and overall suitability for orlistat during your online consultation.
2-Week Supply: Ideal for Initial Assessment
Our 2-week starter packs are perfect when beginning orlistat treatment alongside antibiotics. Generic orlistat 42 capsules cost £16.89 (£15.20 with EDM10), while Xenical 42 capsules cost £21.50 (£19.35 with EDM10). This shorter supply allows your prescriber to monitor how you respond to treatment while taking antibiotics, ensuring both medications work effectively without complications.
4-Week Supply: Balanced Treatment Option
Four-week supplies offer excellent value for established treatment. Generic orlistat 84 capsules cost £32.99 (£29.69 with EDM10), Xenical 84 capsules cost £42.99 (£38.69 with EDM10), while Alli 42 capsules cost £28.99 (£26.09 with EDM10). This duration typically covers most antibiotic courses, allowing seamless continuation of your weight management plan.
8-Week Supply: Extended Treatment Value
Eight-week packs provide significant savings for longer-term treatment. Generic orlistat 168 capsules cost £63.99 (£57.59 with EDM10), Xenical costs £86.99 (£78.29 with EDM10), and Alli 84 capsules cost £54.99 (£49.49 with EDM10). This supply length works well when antibiotic treatment is complete and you're continuing orlistat as part of your structured weight management programme.
12-Week Supply: Maximum Savings Option
Our 12-week supplies offer the best value for committed weight management. Generic orlistat 252 capsules cost £95.99 (£86.39 with EDM10 - save £9.60), Xenical costs £128.99 (£116.09 with EDM10 - save £12.90), and Alli 252 capsules cost £129.99 (£116.99 with EDM10 - save £13.00). These extended supplies are ideal once any antibiotic interactions have been assessed and cleared by your prescriber.
