Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take rimantadine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of infection after you finish the rimantadine, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
