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

What would happenif you take an expired valtrex (valacyclovir)?

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.
