Dosage Of Dapsone
Dapsone comes as a tablet to take by mouth. Dapsone usually is taken either once a day or three times a week. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dapsone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to dapsone.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
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.
