Hi.. Can understand your concern.. As per your complain in pregnancy most of the medicines are contraindicated in pregnancy while only a few can be taken.. Although both clindamycin and azithromycin is well tolerated during pregnancy and has not been seen to cause any serious side effects to the pregnant ladies or the foetus but taking both together is not advisable and taking any one of the two can help you in curing your dental infection and both are not needed.. In case of pain you can take paracetamol for relief.. I would suggest you to consult your gynaecologist and after her consent only you should proceed with taking the antibiotics although if you take any one among the two also it will help in reducing your infection.. Hope this information helps.. If you find the answer helpful kindly write a positive review and click on found this answer helpful as a token of appreciation.. Thanks and regards..
