You could also go on prep. That's $1.3k month without insurance.
Insurance covers prEP as a way to prevent HIV infection.
Rather pointless to talk about the exorbitant price of Truvada. No one is paying for it out of pocket. Additionally, there are many programs available to help finance the medication.
You may want to ask this "friend" to inquire whether his strain of HIV is resistant to Truvada. Rare but possible.
Prep has to be taken every day. Its not a morning after pill.
Actually, maybe not. There is a french study of "PrEP on Demand".
You say: "You may want to ask this "friend" to inquire whether his strain of HIV is resistant to Truvada. Rare but possible."
A person on PrEP doesn't have an HIV strain.
It is a MYTH:
Sorry you misunderstood.
Someone mentioned Prep , and his "friend " is Hiv +.
So his "friend" is positive.
Since this situation is different than what the study was designed for. The study looked at a whole population with randomness. In this situation he is mentioning a single individual with a specific situation.
There was an assumption he was undetectable. If this was an is the case lets assume that then.
Thankfully we have a lot of prior research , some that is conflicting but most that is in concert.
Again bringing in Prep here is the WRONG way to answer here because Prep lowered risk in a population that was large with multiple partners. Since there is presumably 1 partner here "we" can give him a better answer since we can know the specifics of his "friends" health. In the Prep study there was a decrease in transmission. But this individual can do better knowing the specific information.
Most individuals can figure out this calculator for SPECIFIC situations. Choose, semen and mucous membrane and the risk based on a retrospecitve study is generated. I did it for you and the risk is low http://www.mdcalc.com/hiv-needle-stick-risk-assessment-stratification-protocol-rasp/
Or, 1 in 5000. Treatment recommended, but optional, according to the article. For POST exposure prophylaxis.
Last part is knowing what this individuals sensitivities are. If this individual has a strain that is Truvada resistant, Prep is likely to be worthless. If it is sensitive it may help.
