I understand the importance of following my doctors recommendations for malaria. My confusion comes because my primary doc said yes I need preventative, and my kids pedi said no. I talked with a travel medication specialist that said absolutely not necessary based on no instances of malaria in years in Costa Rica. I just want to assure our family is safe, but not take meds unless necessary. Appreciate your feedback and glad to hear the meds did not make you sick - that is my fear!
