My OBGYN said that Tylenol Cold & Sinus was ok. He also said I could take Sudafed.
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.
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!
Saline spray is all natural and will help to clear your sinuses.
I took Flonase and Zyrtech or Claritin. You can also take Benadryl.
I had a list given and mucinex was something I took when I got sick
Go and talk to your doctor. Any pharmacist worth their salt will tell you the same
