Antihypertensive not used in the management of PIH is:

Ref. KDT. Page. 145 Anti-hypertensives to be avoided during pregnancy Diuretics: Tend to reduce blood volume— accentuate uteroplacental perfusion deficit (of toxaemia)—increase risk of foetal wastage, placental infarcts, miscarriage, stillbirth. ACE inhibitors, AT antagonists: Risk of foetal damage, growth retardation. Nonselective b blockers: Propranolol has been implicated to cause low birth weight, decreased placental size, neonatal bradycardia and hypoglycaemia. Sod. nitroprusside: Contraindicated in eclampsia. Antihypertensives found safer during pregnancy Hydralazine
Methyldopa (a positive Coombs’ test occurs, but has no adverse implication). Dihydropyridine CCBs: discontinue before labour as they weaken uterine contractions. Cardioselective b blockers and those with ISA, e.g. atenolol, metoprolol, pindolol, acebutolol: may be used if no other choice.
 Prazosin and clonidine—provided that postural hypotension can be avoided.
