In response to your question about whether post-exposure medication can prevent sexually transmitted infections (STIs) after intercourse, it is important to understand the context and the specifics of STIs, as well as the available preventive measures.

Firstly, it is crucial to clarify that there are specific medications designed for post-exposure prophylaxis (PEP) for certain STIs, particularly HIV. PEP involves taking antiretroviral medicines after potentially being exposed to HIV to prevent infection. However, PEP must be started within 72 hours after a possible exposure and is not effective for other STIs such as gonorrhea, chlamydia, syphilis, or human papillomavirus (HPV), which is what your girlfriend has been diagnosed with (commonly referred to as genital warts or condylomata acuminata).

In your case, since you used a condom during intercourse, the risk of transmitting HPV is significantly reduced, but not entirely eliminated. HPV can be transmitted through skin-to-skin contact in the genital area, which can occur even when using condoms. The fact that you mentioned potential contact with your hands and scrotum does raise some concern, but the risk remains relatively low if the condom was used correctly throughout the intercourse.

For HPV, there is currently no cure, but there are vaccines available (such as Gardasil) that can prevent the types of HPV that most commonly cause genital warts and cervical cancer. If your girlfriend has just developed warts, it is advisable for her to discuss treatment options with her healthcare provider. Treatments may include topical medications, cryotherapy, or other procedures to remove the warts.

As for your concern about post-exposure medication, there is no specific medication that can be taken after exposure to prevent HPV or other STIs like chlamydia or gonorrhea. The best course of action is to monitor for any symptoms and to get tested for STIs if you have concerns. Regular screening is recommended for sexually active individuals, especially when new partners are involved.

In summary, while there are effective preventive measures for certain STIs like HIV, there are no post-exposure medications for HPV or other common STIs. It is essential to maintain open communication with your partner about sexual health, and both of you should consider regular STI screenings as part of your sexual health routine. If you have any further concerns or symptoms, it is advisable to consult a healthcare provider for personalized advice and testing.
