Understanding Orlistat Side Effects & Prescription Options

Can Orlistat Cause Diarrhea? Understanding the Side Effects

Yes, orlistat can cause diarrhea and other gastrointestinal effects. These are amongst the most common side effects experienced by people taking prescription weight loss medication. Orlistat works by blocking approximately one third of dietary fat from being absorbed in your gut. This unabsorbed fat must leave your body naturally, which can result in loose stools, oily discharge, and increased bowel movement frequency.

The likelihood and severity of these effects directly relate to the fat content of your meals. Following a reduced-calorie, lower-fat diet (approximately 15g fat per meal) significantly reduces gastrointestinal side effects whilst supporting your weight management goals.

Prescription Orlistat Options at EverydayMeds

We supply both generic orlistat 120mg and branded Xenical 120mg following online clinical assessment. Both contain identical active ingredients and work in exactly the same way:

Orlistat 120mg (Generic): 2 weeks £16.89, 4 weeks £32.99, 8 weeks £63.99, 12 weeks £95.99. Save 10% with code EDM10 on every order.

Xenical 120mg (Branded): 2 weeks £21.50, 4 weeks £42.99, 8 weeks £86.99, 12 weeks £128.99. EDM10 code applies for additional savings.

Generic orlistat offers identical clinical benefits to Xenical at significantly lower cost, making prescription weight loss treatment more accessible.

Managing Gastrointestinal Side Effects

Most patients find side effects become more manageable within the first few weeks of treatment. Key strategies include keeping meals low in fat, taking orlistat with each main meal containing fat, and wearing dark clothing or protective undergarments initially. If you experience severe abdominal pain, rectal bleeding, or signs of liver problems, seek immediate medical attention.

Our online consultation includes comprehensive guidance on managing side effects and optimising your treatment plan. UK-licensed prescribers review your medical history and current medications before approving treatment.

Who Can Take Prescription Orlistat?

Orlistat may be prescribed for adults with a BMI of 30 kg/m² or above, or those with a BMI of 28 kg/m² or above with weight-related health conditions such as type 2 diabetes or high blood pressure. Treatment must always be combined with a reduced-calorie, lower-fat diet and increased physical activity.

Complete our online health questionnaire to determine your suitability. Our prescribers assess each application individually, ensuring safe and appropriate treatment recommendations.
