<s>[INST] my husband is currently on a course of tetalysal for three months. can we try to conceive while he is on this medication or will there be adverse effects on the baby? Alternatively how long after he stops the course of antibiotics will it be safe to try and conceive? [/INST] Hi, Yes, as it can be taken safely by your husband. Betrayal (Lymecycline) is used for the treatment of infections caused by susceptible bacteria. If given to a pregnant mother it can cause harmful effects like bone and teeth abnormalities in the baby hence it is contraindicated during pregnancy. However, let your husband complete the course of betrayal as it is not going to affect your pregnancy and there will not be any adverse effects on the baby. Hope I have answered your query. Let me know if I can assist you further.  </s>
