Summary
Rimantadine is used to treat and prevent influenza A virus infections, which are flu infections caused by a specific type of virus. It helps reduce symptoms like fever and body aches and is most effective when started within 48 hours of symptom onset.
Rimantadine works by stopping the influenza A virus from multiplying in your body. It blocks a viral protein called M2, which is essential for the virus to spread. This action helps reduce flu symptoms and shortens the duration of the illness.
The usual starting dose for adults is 100 mg twice daily. For some, especially the elderly or those with kidney issues, a lower dose of 100 mg once daily may be recommended. Rimantadine is taken as a pill, with or without food.
Common side effects of Rimantadine include nausea, dizziness, and insomnia, which is difficulty sleeping. These effects are usually mild and temporary. If you experience any new or worsening symptoms, contact your doctor for advice.
Rimantadine should not be used by people with severe liver or kidney problems. It may cause dizziness or confusion, especially in the elderly. Avoid alcohol, which can increase these side effects. Always consult your doctor to ensure Rimantadine is safe for you.
