Yes, Monocef (Ceftriaxone) is generally considered safe to use during pregnancy, as it belongs to a class of antibiotics that typically do not harm the developing baby. However, you should never self-medicate. A fever is a symptom, not a disease, and can be caused by viral infections (which antibiotics do not treat) or other underlying issues. It is crucial to consult your gynecologist or doctor immediately. They will diagnose the actual cause of your fever and prescribe Monocef or another appropriate medication only if a bacterial infection is confirmed, ensuring the correct and safe dosage for you and your baby.
