With Acyclovir, you do not necessarily have to give up alcohol completely, but if you minimize drinking and make arrangements so that you do not have to drive or operate machinery after drinking, you should be safe, and the medication should work as expected. If you have any doubts about your ability to handle alcohol, then it is best to avoid it altogether.
Acyclovir can be safely purchased online through medical facilitators like AccessRx.com. This site contracts with U.S.-licensed physicians and pharmacists and has safely dispensed brand name, FDA-approved medications like Zovirax (Acyclovir) to thousands of consumers since 1998.
