Examine whether anti-hypertensive therapy is safe if used during pregnancy:

Angiotensin converting enzyme (ACE) inhibitors and angiotensin-receptor blockers are teratogenic. This is most proven for use of these drugs during the second and third trimesters. Therefore any medication's changes should be early performed, ideally in the preconception period.

Based on the following notes, reconsider pharmacological therapy: 

R 1.7a-d Safe and effective alternatives to ACE inhibitors and angiotensin-receptor blockers for treating hypertension during pregnancy include:

• methyldopa
• labetalol
• prazosin
• diltiazem
• clonidine (ungraded)

Does pharmacological therapy need to be modified?
