Go and talk to your doctor. Any pharmacist worth their salt will tell you the same
I had a list given and mucinex was something I took when I got sick
I took Flonase and Zyrtech or Claritin. You can also take Benadryl.
Saline spray is all natural and will help to clear your sinuses.
doTERRA Breathe is a wonderful natural remedy to use as well. Helps clear out the sinus and their On Gaurd is a good protection oil. I diffuse it throughout my house and it has helped both me and my 7week old son get over our colds. Let me know if you are interested!
I had a sinus infection at 32 weeks. My Dr put me on antibiotics and recommended tylenol cold and sinus for my symptoms but I don't think you're supposed to take that during the first trimester. Check with your doctor.
My OBGYN said that Tylenol Cold & Sinus was ok. He also said I could take Sudafed.
