Valacyclovir Hydrochloride Dosage
I took 2 gm valacyclovir twice yesterday as I had an outbreak occurring. Can I repeat that dosage today? I still feel like the outbreak isn't over.
No more needed: There is no need for more. With the large doses of valayclovir you took, the drug is still in your system. It always takes at least a few days for complete healing -- but drug needs to be in your system only 24 hours. Your outbreak should continue to improve. Possible exception: if your initial infection was only a few weeks ago and this is your 1st or 2nd recurrence, maybe need 1-2 days more. ...Read more
Ob/gyn not helpful with managing herpes outbrks. Where should I go? On Valtrex (valacyclovir) daily 1gr. Can i up dosage? What other kind of dr. Should i consult?

The next time you get an outbreak, it would be useful to get the lesion cultured or sent for pcr testing to confirm the diagnosis. ...Read moreSee 1 more doctor answer
Should I take lysine for my chronic cold sores? If so, as treatment or to prevent? Dosage? Currently take Valtrex (valacyclovir) and use Abreva.
Pay attention: Abreva does very little, not worth the money. l-Lysine is an old scam: it did nothing 40 years ago and it does nothing now. Simple understanding of biochemistry of amino acids is enough to dispel this silly scam. See a dermatologist. Are you sure it is herpes? Valacyclovir can be helpful if dosed properly and is safe. Usual dose is 2gram at very first prodromal symptoms of each attack. Sometimes d ...Read more

1st dose Valtrex (valacyclovir) for cold sores. Dizzy with funny vision. I do have MS ... Could it be my MS or the valtrex (valacyclovir). Should i stick to zovirax instead?
VIRAL INFECTIONS: Viruses can promote worsening of ms, even a full blown relapse. Sounds like you recently had labor and delivery, and pregnancy is protective, but breastfeeding is not so protective, and you may indeed have an emerging relapse or progressive symptoms. The long and short here is the need to see a neurologist and restart a potent disease modifying drug. Do not worry about which viral drug is used. ...Read more

Probably nothing: All medicines degrade with time. Just cause it expired doesn't mean its poisonous. Just won't work as well as unexpired medicine. Actually, it really depends on how old the medicine is. If its relatively soon after the expiration date, i'm sure its still good. All bets are off its over a year past. ...Read moreSee 1 more doctor answer
