Hello dear. Welcome to Healthcaremagic. I read your query and I understand your concern. You can use acetaminophen to lower high body temperature. Erythromycin is safe in pregnancy but a doctor should examine you and will decide if you really need to take it. Take care. Hope my answer was helpful, if you have any other questions I ll be glad to help you. Best regards, Dr. Olgeta Xhufka ( general and family physician ).
