Were you at a regular doctors office or the ob/gyn? If you weren t at the ob/gyn I d be a little skeptical of taking the med. I am surprised they would give you anything with one high blood pressure reading. The high BP with pre-eclampsia is usually noted after 24 weeks and could mean other things if noticed before 24 weeks. I d just keep a close eye on the BP, and if it still runs high constantly talk with your ob/gyn about any kind of meds. I usually don t tell anyone to quit taking medication, but if it was a primary care doctor I would honestly talk to the ob/gyn before continuing it.
