However, like all medications, niclosamide should be used under the guidance of a healthcare provider. It's important to follow the prescribed dosage and treatment plan. Niclosamide is usually well-tolerated, but some people might experience mild side effects like nausea, abdominal discomfort, or headaches.

It's crucial to use niclosamide only for the conditions it’s prescribed for and to complete the full course of treatment to ensure the infection is fully eradicated. Misuse or incomplete treatment can lead to recurrence of the infection or resistance.

If you have any concerns about taking niclosamide or experience any unusual symptoms, consult your healthcare provider. They can provide personalized advice and ensure the medication is appropriate for your specific condition.
