Xenical, while effective for weight loss, can cause gastrointestinal side effects. Expect changes in bowel habits, including oily spotting, frequent bowel movements, and urgent need to defecate. These usually lessen as your body adjusts. However, severe diarrhea or rectal bleeding requires immediate medical attention.
Dietary Considerations
Xenical works by preventing your body from absorbing some dietary fat. To maximize benefits and minimize side effects, follow a low-fat diet. This means limiting fatty, fried, and processed foods. Focus on lean protein, fruits, vegetables, and whole grains.
Medication Interactions
Xenical can interact with certain medications, including cyclosporine, anticoagulants, and some HIV medications. Consult your doctor before starting Xenical if you’re taking other prescriptions. This is critical for safe usage.
Other Potential Side Effects
Less common, but still possible side effects include headache, abdominal pain, and flatulence. These usually are mild and temporary. If symptoms persist or worsen, seek medical advice.
| Oily spotting | Common | Adjust diet; consult doctor if severe |
| Frequent bowel movements | Common | Adjust diet; consider over-the-counter anti-diarrheal medication (after consulting your doctor) |
| Abdominal pain | Less common | Consult doctor if persistent or severe |
| Headache | Less common | Over-the-counter pain relief may help; consult doctor if persistent |
Pregnancy and Breastfeeding
Xenical is not recommended during pregnancy or breastfeeding. Discuss alternative weight-loss strategies with your doctor if you are pregnant or breastfeeding.
