If im pregnant and have a fever what medicine could I take to get rid of it?

Tylenol (acetaminophen) In fact anything that bears the tylenol (acetaminophen) name ex tylenol (acetaminophen) sinus, etc) should be safe in pregnancy. Look for the generic equivalent for any of these products to save a buck.
Depends. The cause of your immune response triggering a fever needs determined. Acetaminophen at less than 2500 mgs a day is safe, but ultimately the cause of your temperature needs determined if it persists beyond 24 hrs because you are pregnant.
