Take this medication by mouth with or without food, usually once daily or as directed by your doctor.
Medications for heartburn/reducing stomach acid (e.g., large amounts of antacids, ranitidine, famotidine), or didanosine may prevent full absorption of dapsone into your bloodstream, possibly reducing its effectiveness. Therefore, separate your dose of dapsone from your doses of any of these products by at least 2 hours. Ask your doctor or pharmacist for more details.
If you are taking dapsone for a skin disorder, your doctor may start you on a low dose of dapsone and gradually adjust your dose to control your disease. If you are taking this medication to treat Hansen's disease or to prevent infections due to HIV, the drug is usually taken for years or for life.
Dosage is based on your medical condition and response to treatment. In children, the dosage is also based on age and weight.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Tell your doctor if your condition worsens.
