Brand Aczone gel

This medication is used to treat a certain type of skin disorder (dermatitis herpetiformis). It is also used with other drugs to treat Hansen's disease. Dapsone belongs to a class of drugs known as sulfones. It works by decreasing swelling (inflammation) and stopping the growth of bacteria. This medication will not work for viral infections (e.g., common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.

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.

If using this drug to treat Hansen's disease, note that as your immune system helps fight the infection, you may notice skin sores worsening, and numbness/pain/tingling or muscle weakness.

Although most antibiotics probably do not affect hormonal birth control such as pills, patch, or ring, some antibiotics may decrease their effectiveness. This could cause pregnancy. Examples include rifamycins such as rifampin or rifabutin. Be sure to ask your doctor or pharmacist if you should use additional reliable birth control methods while using this antibiotic.

Dapsone can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Therefore, seek immediate medical attention if you develop any rash. A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
