<s>[INST] Hi doctor, I had unprotected sex and have consulted a doctor after that. He told me to go for PEP immediately. So, I started PEP after three days of exposure with one Tablet of Lamivudine and Zidovudine along with one Efavirenz tablet. I have taken PEP after 66 hours of exposure. Will it be helpful? Please let me know. [/INST] Hello. For further doubts consult a sexologist online --> </s>
