Antihypertensive Medication during the First Trimester of Pregnancy

Hypertensive disorders during pregnancy constitute a significant risk factor for maternal and fetal outcomes, necessitating antihypertensive treatment. However, current data concerning the safety of in utero exposure to antihypertensive medication are controversial. While some studies recommend the administration of certain agents, others underline the possible adverse effects on fetal development. In general, a-methyldopa, β-blockers and calcium channel blockers are the first or second treatment line for hypertension during pregnancy. However, ACEIs, ARBs and diuretics are mostly contraindicated, as the potential risk outweighs the benefits of their administration. Additionally, several drugs should be avoided, due to the lack of data regarding their safety. Women are often concerned about the safety of antihypertensives and as a result, many do not take their treatment as prescribed. Shared decision-making aids have been shown to reduce women's uncertainty about taking antihypertensives and increase the number of women taking them as prescribed.
