Drug-induced pemphigus is a rare autoimmune disorder that is caused by certain medications. It is characterized by the formation of blisters and sores on the skin and mucous membranes. Symptoms of drug-induced pemphigus include painful blisters, itching, redness, and swelling. Treatment typically involves discontinuing the medication that is causing the condition and using topical or oral corticosteroids to reduce inflammation.

The symptoms of drug-induced pemphigus vary depending on the type of drug involved, but may include:

-Itchy, red, raised patches of skin

-Blisters that may be filled with fluid or pus

-Painful sores that may be slow to heal

-Thickening and hardening of the skin

-Thinning of the skin

-Scarring of the skin

-Hair loss

-Changes in skin color

-Fever

-Fatigue

-Joint pain

-Swollen lymph nodes

Drug-induced pemphigus is caused by certain medications, such as penicillamine, captopril, and certain antibiotics. Other causes may include exposure to certain chemicals, such as pesticides, and radiation therapy.

The treatment for drug-induced pemphigus depends on the underlying cause. In some cases, the drug causing the condition may need to be stopped or changed. In other cases, medications such as corticosteroids, immunosuppressants, or biologic agents may be used to reduce inflammation and suppress the immune system. In severe cases, plasmapheresis (a process of removing and replacing the blood plasma) may be used.

1. Use of certain medications, such as antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), and anticonvulsants.

2. Exposure to certain chemicals, such as pesticides, solvents, and dyes.

3. Having a weakened immune system due to certain medical conditions, such as HIV/AIDS, cancer, or autoimmune diseases.

4. Being of advanced age.

5. Having a family history of pemphigus.

At this time, there is no cure for drug-induced pemphigus. Treatment typically involves discontinuing the medication that is causing the condition, and then managing the symptoms with medications such as corticosteroids, immunosuppressants, and other medications.
