Acyclovir 800mg, took one pill last night and woke w/ swollen face. taking for shingles, rash is on face as well. please help me i have no ins..

Allergic reaction: Your swollen face is probably an allergic reaction to acyclovir. I wouldn't try taking another dose. However, your only other 2 options are valacyclovir (valtrex) and Famciclovir (famvir), both of which are more costly, and you may be allergic to all of the anti-viral meds of this type. You might try using a medication discount card but these meds may or may not be discounted.

Angioedema: An allergic like reaction to Acyclovir is a possible explanation for your facial swelling. It can be accompanied by a rash, swollen face, lips, tongue, as well as throat swelling which could be life threatening. Would need to stop the medication. Facial shingles should be managed by a doctor. Can't rule out ocular herpes in your case. Er is a good option or at least urgent care.
