Severe ringworm and 12 weeks pregnant. can i take oral lamisil (terbinafine) during pregnancy?

Good question!: First, make sure of the diagnosis of ringworm. Next, make sure you are not able to use a topical cream or ointment to treat this. Lamasil is "probably" safe in the second and third trimesters but why take the chance if a less "toxic" approach can be made. First, make sure of the diagnosis. If in doubt, check your your obstetrician and with your pcp. Perhaps a dermatologist may weigh in?
