Hi all, can anyone please advise as to what dosage of 400mg aciclovir I should take pre & post lip blush? Ive had sun blisters on my lips in the past (a while ago)!and have been told to take these 5 days before and 5 days after. The lady who is doing my lips is on holiday and not back until my appointment. Google etc states 2 per day 5 days before & 5 days after but the online dosage states one 5 times per day! I only have 28 tabs and won't have enough if that's the case! I asked the receptionist who "thinks" 2 x 400 mg is correct but couldn't be sure! Has anyone else had this and if so what dosage was ok, or not enough or did you have a breakout? TIA very much for your help!
