Avlosulfon oral Uses

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.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used to treat or prevent a certain lung infection due to HIV (pneumocystis pneumonia), to prevent a certain brain infection due to HIV (toxoplasmosis), and to treat skin conditions in certain immune system disorders (e.g., systemic lupus erythematosus-SLE).

How to use Avlosulfon oral

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.

Avlosulfon oral Side Effects

Nausea, vomiting, loss of appetite, dizziness, or blurred vision may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: unusually fast heartbeat, unusually fast breathing, bluish lips/skin, chest pain, mental/mood changes, muscle weakness, difficulty urinating.

This drug may rarely cause very serious low blood counts (bone marrow suppression) or liver disease. Seek immediate medical attention if you develop signs of an infection (e.g., fever, chills, persistent sore throat), easy bruising/bleeding, unusual tiredness, pale skin, yellowing eyes/skin, dark urine, stomach/abdominal pain.

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, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
