Which medication might cause cold extremities as a side effect?

The medication that might cause cold extremities as a side effect is Tenormin. This drug is a beta-blocker, and its function involves decreasing the heart rate and reducing the force of the heart's contractions, which can lead to reduced blood flow to the limbs. This reduction in peripheral circulation can manifest as cold extremities since the body prioritizes blood flow to vital organs over the periphery when the heart is working less aggressively.

In contrast, Tylenol is an analgesic and antipyretic that is not typically associated with circulation changes, Sinemet is mainly used for Parkinson’s disease and does not commonly cause cold extremities, and Tegretol is an anticonvulsant and mood stabilizer, with a different side effect profile that does not typically include peripheral coldness. Understanding these differences highlights how various classes of medications can impact peripheral circulation and body temperature regulation.
