I’m having severe welt like hives. I was on macrobid for a UTI and took my last dose on Monday. I’m also taking progesterone because I’m 7 weeks pregnant and I’m at high risk for miscarriage. Do you think the macrobid could be causing the hives even though my last dose was Monday or do you think progesterone could be the cause? Im due to take the progesterone right now and I don’t know what to do.
Hello dear,welcome to Ask a doctor service. I reviewed your query and here is my advice. Both of them may be the causes of allergic reaction. Most probably is macrobid.If it is progesterone change the brand or type of synthetic progesterone. The injection should be done under medical supervision. You may need prednisone injection. Hope I have answered the question. Let me know if I can assist you further.
