Dear Keenegirl:
Acyclovir is an antiviral agent, it does not treat bacterial infection.
It is important to find out what is causing your sever sore throat. It may be cold, flu, allergy, Strep throat, tonsillitis, etc.
I know you don't have health insurance, but there may be low-cost county clinic you can have access to. If you have bacterial infection, like Strep throat, acyclovir will not treat it.
Please seek professional medical help as soon as possible!
Good luck!

sore troat I mean,,,, sorry for the spelling... lol...
though, I am not yet an RPh,
Our instructor thought us, not to drink antibiotics without physicians advice, Acyclovir is an antiviral drug. It is best taken for patients having chicken pox.
And you said you have soar throat. Soar throat is cause by bacteria, I think you need antibiotics, but my best advice is to have a check up to your doctor first. Because, you have allergy to some antibiotics and so that they can give you the right antibiotics for your soar throat. (there are some case that a person was already resistant to a certain antibiotics due to improper medication)
