You should not drink alcohol when taking nifedipine extended-release tablets. Nifedipine extended-release tablets are one of the five major classes of antihypertensive drugs commonly used as calcium antagonists. The application process can result in lower blood pressure, as well as possible side effects of increased heart rate and facial flushing. Lower blood pressure is often associated with vasodilation, which can also be caused by alcohol consumption. Drinking alcohol and nifedipine extended-release tablets together often make the efficacy of blood pressure lowering more pronounced, and some patients even experience hypotension, so drinking alcohol is not recommended. In addition, the use of nifedipine extended-release tablets can cause side effects, such as flushing of the face and accelerated heart rate, and drinking alcohol tends to increase sympathetic excitability, resulting in an accelerated heart rate, which together often results in symptomatic tachycardia, causing discomfort to the patient and even aggravating existing myocardial ischemia. Therefore, it is not recommended to drink alcohol during the course of and while taking Nifedipine Extended Release Tablets.
