What are the best medicine for viral infection?

Mom's remedies: Unfortunately medicines like antibiotics do not treat viral infections, so it's best to follow all the advice your mom used to give you: get lots of rest and drink fluids! chicken soup and tea may also help. You may take tylenol (acetaminophen) for fever and muscle aches. Remember to wash your hands so you don't pass the infection along!

It depends what viru: Most of the viral infections get better by themselves and do not need and antiviral antibiotics but if you are diagnosed with inflenza and start tamiflu (oseltamivir) asap it shortens the course and avoid complications.Same hold true with varicella and herpes zoster and you have choice of antiviral antibiotics if used early can shrten the course and we also use drugs for herpes simplex and HIV and others.
