I had my daughter at 37 weeks in 2010 due to PIH. I am currently 28 weeks pregnant with my son, and have been on BP meds since about 20 weeks. I started at 100 mg Labetalol once a day, was raised to 100 mg twice a day not long after that, and just last week my dose was raised to 200 mg twice a day. With taking 200 mg twice a day, I find that it drops my BP for about 4 hours and makes me feel cruddy, and then my pressures go right back up for the rest of the day. I called my OB's office yesterday, but they were gone for the weekend. I just wondered if anyone had ever been advised to stretch their doses out through the day. Maybe take 100 mg in the morning, and then 100 mg in the afternoon?
