Red rash followed by pustule-like bumps...

[gg_beat]

I was on amoxicillin for an infection during September of this year.  During the time that I was on the antibiotic, I developed this small red patch/rash that after a few days, would be followed by pustule-like bumps.  They developed on both of my shins, on my right foot, my chest and on both sides of my head.  The rashes occurred twice on each section mentioned.  Could this be a side effect from the medication or something else?

Hi
Welcome to the MedHelp forum!
Yes, it could be allergic reaction to antibiotic. However this should go away with an anti allergic. Other than this can also be a part of contact dermatitis like contact with soap, detergents, powder etc. Pemphigus and bullous pemphigoid are the other conditions that should be ruled out.
There are other causes of blisters too but probably they do not apply in your case. These are Dermatitis herpetiformis, chronic bullous dermatosis, cutaneous radiation syndrome (following a radiation--maybe for cancers or X-rays or CT scans), and Epidermolysis Bullosa.
Herpes and shingles are the other possibilities.
If rash does not respond to antiallergic, consult a skin specialist. Take care!

this could be because you are alergic to the meds. you should go to your doc and see what they have to say. if you dont have time to do that go to a CVS min clin
