If abnormal neurological signals arise while taking tinidazole, the medication should be stopped. Tinidazole is contraindicated during the first trimester of pregnancy and throughout lactation. While there is no indication that tinidazole is dangerous during pregnancy, it must be used during the latter two trimesters if the potential benefits outweigh the risk to the mother and fetus.
