Does Amoxicillin cure a skin rash?

Question

Hi doctor,

I may have mistaken a fungal skin rash for a bacterial infection. I am a 32-years-old male. I noticed a rash under my left breast area seven years ago. It was pink, raised, and scaly. Oval and random shapen bumps. I assumed it was tinea, or a fungal infection related to ringworm. I tried Lamisil cream and similar OTC (over the counter) treatments. None of it worked. I then visited a dermatologist, who prescribed a stronger cream (Econazole Nitrate), and Fluconazole pills. Again none of them worked. I got wisdom teeth removed, and the surgeon prescribed me Amoxicillin. Obviously, this is unrelated to the skin rash, but somehow, during the two weeks I took the Amoxicillin, the skin rash disappeared completely. After two months, I faced the same problem and the rash started coming back. I went to the dermatologist and the same process repeated, nothing worked. I went back to the oral surgeon and convinced him to give me a refill on the Amoxicillin for the purpose of killing this rash, and yet again, it is working. The rash is going away. I have since done some research online, and i cannot figure out what is going on. Apparently, Amoxicillin is used for bacteria and is ineffective against fungus, so perhaps what I have is not a fungus at all. Maybe I have an autoimmune disorder? I need help from a professional who knows what the problem might be.

Thanks.

Hi,

Welcome to icliniq.

I am glad you chose icliniq for your medical-related queries.

I understand your concern and will try to help you with it.

Yes, I do agree that you may have bacterial infections instead of fungus, that is why Amoxicillin works well in your case. But the reason for recurrence is Staphylococcus aureus. It is most commonly carried in the nostrils, armpits, between the legs and in the cleft between the buttocks. It may be transferred to other sites from the nostrils through the fingernails. So you should follow certain general measures:

If you are overweight, try to reduce your weight. Practice regular exercise.
Follow a balanced healthy diet with meat, plenty of fruit and vegetables.
Avoid smoking.
Wash your whole body once a day with soap or cleanser and water. Wash your hands several times daily or use antiseptic hand rubs.
Do not share your towel with other family members.
Maintain a clean handkerchief and do not pick your nose.
Change your underclothes and nightwear regularly.
Try to avoid activities that cause sweating and friction from clothing, such as squash and jogging.
If you are iron deficient, a course of iron tablets may help reduce the risk of infection.
Check your blood sugar.

I am thankful that you have confidence in me to help you.
