To prevent Genital HSV 1 from being passed on to my partner, would it help if we both take Valtrex?

Hi again,

Thanks for posting multiple questions.  Like I said before, I'm not a doctor, so I am not a medical authority or expert.  But since I have herpes I think I can help you.

I think it's good that you are taking Valtrex as suppressive therapy since you are concerned about infecting your partner.  It's true that taking daily anti-virals will reduce the risk of transmission by hindering the replication of the herpes virus in your body.  However, I think that having your partner take Valtrex would be overkill.  If he does not have herpes, the Valtrex will do nothing in his body, but may burn a hole in his wallet and potentially negatively affect his access to health insurance in the future.  

I am opposed to taking medicine on a regular basis unless it is absolutely necessary.  In your case, it may be necessary for you to be on suppressive therapy if you have frequent outbreaks or if you're trying to have a child, etc.  However, it is not necessary, and I might even say it's unreasonable, for your partner to take the medicine as well.  If you are careful while you are intimate, continue taking your medication, and follow the information from the links I posted to your other question, he should be fine.

Thanks again and let me know how it goes!
