Is it safe to take Pen-Vi-K tablets for an open lesion on my ankle?
Patient: I have a small open lesion on my ankle just above my ankle bone. I am three days from home on a tour bus. I am type ll diabetic. I have a foil packet with 2 Pen-Vi-K tablets with no dosage size on the packet. I was given these some time in the past. I am not allergic to penicillin and have taken it in the past. I m also on warfarin. Do you think it would be safe to take this medicine? Doctor: Hi just having an open lesion, without having pus, is not an indication to take  antibiotics . I suggest you do regular dressing of the open lesion above your ankle with good antiseptic cream and if pus comes or redness increases then consult your doctor before starting antibiotics.
