Does the use of antihistamines affect the liklihood of transmission?

Also, if you dont use anithistimines, does being irritated increase the chances of transmission from oral sex?

Answer

Answer: Simon Collins

Antihistamines are usually prescribed for a range of allergy-related conditions.

I have not seen any studies showing they would reduce risk of HIV transmission.

However, if your allergy includes a reaction where you have a rash, especially with broken skin, this could be a risk for HIV, if it comes into contact with blood, semen or other genital fluids.

Oral sex is generally a low risk, because saliva is not infectious.
