Precautions While Using This Medicine

It is very important that your doctor check you at regular visits for any blood problems that may be caused by this medicine, especially if you will be taking this medicine in high doses for toxoplasmosis.

If your symptoms do not improve within a few days or if they become worse, check with your doctor.

If this medicine causes anemia, your doctor may want you to take leucovorin (e.g., folinic acid, Wellcovorin) to help clear up the anemia. If so, it is important to take the leucovorin every day while you are taking this medicine. Do not miss any doses.

Pyrimethamine, especially in high doses, may cause blood problems. These problems may result in a greater chance of certain infections, slow healing, and bleeding of the gums. Therefore, you should be careful when using regular toothbrushes, dental floss, and toothpicks. Dental work should be delayed until your blood counts have returned to normal. Check with your medical doctor or dentist if you have any questions about proper oral hygiene (mouth care) during treatment.
