Are we thinking of the same drug? Because Valtrex is pretty safe as long as your kidneys are normal and you drink enough water every day. I take 500 mg daily to prevent 5 to 10 (at least!) cold sores per year. My quality of life is so much higher with this drug (imagine not being able to be intimate on like half of all your dates...) For people like me who get cold sores at the drop of a hat (or shaving or even a sharp cold breeze), it’s a fine risk, and I’d even be willing to risk more.

The more disturbing side effects are rare, but very very serious. I would consider the drug for, say, shingles. But not a chance for a cold sore that’s nothing but a minor nuisance for a few days: https://www.drugs.com/sfx/valtrex-side-effects.html https://www.drugs.com/sfx/valtrex-side-effects.html

  This is why it’s a prescription. You should go over risks and any symptoms with a doctor and get regular checkups.

  Virtually any drug looks scary when viewing its side effects in totality like that. The throwaway you're replying to is correct in saying it's a pretty safe drug. >But not a chance for a cold sore that’s nothing but a minor nuisance for a few days Except the virus regularly sheds asymptomatically, and Valacyclovir reduces that risk significantly, thus affording far more protection to one's partners. I otherwise agree with you, but for sexually active adults who are positive, taking it is virtually an obligation unless their partner(s) already have the virus as well.

    Exactly! It’s also way more than a “minor nuisance”. Try two weeks of painful, disgusting scabbing, washing your hands constantly (God help you if you self-infect your eye, which is totally a thing), and a decent amount of pain and self-esteem problems. Oh, and forget about using your mouth for pretty much anything besides eating, and even that can be difficult. It’s totallt a quality of life thing. I have so many outbreaks, which can be caused by something as benign as shaving or kissing someone with a beard (and I happen to be into dudes), that there really is no other option. I guess I could spend my life breaking out in gross herpes sores, or... I could take a pill every day like I have been for years with no ill effects, and enjoy the things that everyone else does.

      Good point. For some people outbreaks can be frequent and/or severe, and it really does become a quality of life thing in that case.

You actually buy and take some kind of man-made chemical every single day to avoid getting a cold sore every month or two? Here is the list of known side-effects here (sorry about the formatting but i guess carriage returns don't translate well): Along with its needed effects, valacyclovir (the active ingredient contained in Valtrex) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention. Check with your doctor immediately if any of the following side effects occur while taking valacyclovir: More common Discouragement feeling sad or empty irritability lack of appetite loss of interest or pleasure tiredness trouble concentrating trouble sleeping Rare Black, tarry stools chest pain chills cough decreased frequency or output of urine fever flu-like symptoms headache lower back or side pain reduced mental alertness shortness of breath yellow eyes or skin Incidence not known Actions that are out of control agitation anxiety back, leg, or stomach pains bleeding gums blood in urine or stools blurred vision change in consciousness change in mental status changes in behavior, especially in interactions with other people changes in patterns and rhythms of speech dark or bloody urine difficult or labored breathing difficulty speaking difficulty swallowing dizziness drowsiness dry mouth fast, pounding, or irregular heartbeat or pulse feeling that others are watching you or controlling your behavior feeling that others can hear your thoughts feeling, seeing, or hearing things that are not there general tiredness and weakness hyperventilation increased thirst itching lightheadedness when getting up from a lying or sitting position light-colored stools loss of consciousness mood or mental changes nausea and vomiting nervousness pale color of skin pinpoint red spots on the skin pounding in the ears puffiness or swelling of the eyelids or around the eyes, face, lips, or tongue redness of the skin restlessness seeing, hearing, or feeling things that are not there seizures severe mood or mental changes shakiness and unsteady walk shakiness in the legs, arms, hands, or feet skin rash slurred speech sores, ulcers, or white spots on the lips or in the mouth stiff neck swelling of the face, fingers, or lower legs swollen or painful glands talking, feeling, and acting with excitement tightness in the chest trembling or shaking of the hands or feet trouble in speaking troubled breathing unsteadiness, trembling, or other problems with muscle control or coordination unusual behavior unusual bleeding or bruising unusual tiredness or weakness upper right abdominal pain vomiting weight gain wheezing Some side effects of valacyclovir may occur that usually do not need medical attention.
