I have bad seasonal allergies. My OB said regular Claritin or Zyrtec are the two safest to take during your pregnancy. When it's really bad, I take Benadryl at night as well plus it helps you sleep better. I am 34 weeks and everything so far so good. I take it in the mornings. Good luck.
Oh.. You can do off brand too. I buy mine at Costco. =)
I was allowed to take suddafed PE *** well
I asked my pharmacist today because I have the same allergy issues - je said Lortadine OTC is perfectly safe (Claritin) just NO Sudafed or Psuedaphedrine (Claritin D or Allegra D). He also said my Flonase is safe. I take both on bad days, but I also diffuse OnGuard Essential Oil which helps tremendously as well. Hope that helps you!
Depending on how far along you are you can take benedryl, my dr says 20 weeks. (Every dr is a little different)
Your OB should at least be able to okay you maybe taking an alergy med like Alavert, call and ask. There is no reason they can't just say 'yes' or 'no' and yiur General isn't an expert in pregnancy so he won't know what's safe.
Mine alleries so bad I had a migraine for a week and my OB instructed me to take my normal alergy meds for 3 days and use a nasal spray. Then I had to stop because I'm not far enough along but that and things like a humidifier and changes air filters in your ac/heat should help
If it is allergies you can take antihistamines like Benadryl while you're pregnant. I take it every day for my allergies. Hope it helps :)
