Consult your doctor immediately if you experience severe side effects. Common side effects are generally mild and temporary, but some require attention.
Common Side Effects
Many experience headache, dizziness, or constipation. These usually subside as your body adjusts. Drink plenty of fluids and consider over-the-counter remedies for constipation, but always check with your doctor or pharmacist before using any additional medication.
Less Common, But Important Side Effects
Pay close attention for signs of allergic reaction, such as rash, itching, or swelling. Report any unusual changes in your heart rhythm or shortness of breath. Drowsiness is possible; avoid driving or operating machinery if affected. Blurred vision also warrants immediate medical attention.
Serious Side Effects: Seek Immediate Medical Help
While rare, serious side effects exist. These include serotonin syndrome (characterized by high fever, muscle rigidity, and confusion), prolonged QT interval (affecting heart rhythm), and liver problems (indicated by jaundice, dark urine, or light-colored stools).
