Suggest Cure For Blisters On The Body

Hi, I'm taking nevirapine 200 mg one in the morning on empty stomach and later I take one nevirapine with truvada after meal. Now I started to develop blisters on my body and they are getting worse, so I went to the clinick and they gave me acyclovir 200 mg, chlorpheniramine and ibunate to heal the blisters but it seems not working. What should I do?
