<s>[INST] I am a 30 year old man. I had Azithral 500mg tablet for throat pain, back pain and fever. We are planning to have a baby. Is there safe to have sex when I am taking this medicine and shortly after this. Is there is traces of antibiotics present in semen.Thanks [/INST] Hi,Don't worry.Azithromycin is a FDA category B drug. It means that it is  not known to cause any adverse effects on pregnancy in animal studies. You can have sex while on treatment and shortly after.The drug gets washed off from the body in 16-17 days time. This is for your information in case you still wish to avoid sex because of this medicine.I hope this helps. </s>
