Dear Friend. See Indocap (indomethacin) has nothing to do with the treatment of herpes, it is used to reduce the pain and inflammation only. It doesn t kill the virus. Its used for symptomatic relief. He is a diabetic and hypertensive too, so i would not recommend its use for a long term as, it can cause kidney damage, and diabetics and hypertensives kidneys are already under stress. He has been given, anti viral acyclovir. So no further treatment for herpes is required. If his pain persists , you can consult an opthalmologist who can give you a local pain killer eye drop. And for skin lesions if he has in the distribution Indomethacin or other pain killers in moderated doses can be used. Mericobal Viva, is methycobalamine and other supplements. He can take them. No problems in taking it, if he has no problems in tolerating them. Yes, it helps in neuropathy. If the pain is severe, other resorts are there, but i don t think we should go for them as he has some pain and itching only. If you still have any problem or confusion, we are always here to answer Stay Healthy
