What medicine can I take for my sinus infection while im pregnant?

Sinus rinses. Sinus congestion is common in pregnancy (rhinitis of pregnancy). If you are just stuffy with clear drainage, try a sinus rinse and/or saline spray. If you have facial pain, purulent drainage, or severe symptoms see your doctor.
See doctor. Any woman who is pregnant should see a doctor before taking any medication over the counter, and should be careful to avoid self-diagnosis; it is not worth the risk of being wrong. Budesonide is the safest nasal steroid used in pregnancy. Some of the most common antibiotics used for bacterial sinusitis (amoxicillin, azithromycin) are generally considered to be safe.
