Xenical, containing orlistat, can cause gastrointestinal side effects. These are often mild and temporary, but understanding them is key.
Common Side Effects
- Gas: Increased gas production is common. Adjust your dietary fat intake to minimize this. Loose stools: You might experience oily stools or increased bowel movements. This usually improves as your body adjusts to the medication. Stomach pain/cramping: Mild abdominal discomfort may occur. Consider smaller, more frequent meals to help digestion. Urgent bowel movements: You may experience a sudden need to have a bowel movement. Plan your activities accordingly.
These effects usually subside as your body adapts, often within a few weeks. If they persist or worsen, contact your doctor.
Less Common but Serious Side Effects
- Kidney stones: Although rare, report any signs of kidney stones (severe pain in your side or back) to your physician immediately. Liver problems: While infrequent, contact your doctor if you experience yellowing of the skin or eyes (jaundice). Allergic reactions: Seek immediate medical attention for any signs of an allergic reaction, such as rash, itching, or difficulty breathing.
Precautions
Dietary Fat: Distribute your daily fat intake evenly across your meals. Avoid high-fat meals, as this increases the likelihood of side effects. Multivitamins: Take your multivitamins at least two hours before or after taking Xenical. Orlistat can interfere with the absorption of certain fat-soluble vitamins. Underlying Health Conditions: Discuss your medical history, including any existing health issues (like kidney or liver problems), with your doctor before starting Xenical. Pregnancy and Breastfeeding: Xenical is not recommended during pregnancy or breastfeeding. Consult your physician. Interactions with other medications: Inform your doctor about all medications you are taking, including over-the-counter drugs, to avoid potential interactions.
