Amlodipine commonly causes ankle swelling due to fluid accumulation, so monitoring and balancing treatment is important. ---

Good point In pregnancy, amlodipine is not first-lineβ€”we prefer labetalol or extended-release nifedipine due to stronger safety evidence. Available data on amlodipine is reassuring but still limited. In lactation, amlodipine is generally considered safe (minimal transfer into breast milk). ---

valid point In reproductive-age women , we generally prefer labetalol or extended-release nifedipine over amlodipine due to better-established safety in pregnancy. Amlodipine can be used if needed, but it’s not first-line in this group. ---

Got to learn pharmacology basics through this article, a very informative and useful piece written.I had a query so do we prefer amlodipine over nifedipine generally for hypertension because of its minimal effects on AV nodal conduction? ---

The most common and exam-favorite adverse effect of amlodipine is peripheral (ankle) edema. It occurs mainly due to arteriolar vasodilation.
