Is it okay to take two extended-release nifedipine tablets at once?

It is feasible to take two tablets of nifedipine sustained-release tablets at once; however, the exact dosage should be determined based on the patient's specific condition and the physician's recommendation. Nifedipine sustained-release tablets are calcium channel blockers primarily used to treat hypertension and angina pectoris, especially as the first-line treatment for patients with variant angina. For patients requiring a dosage increase, such as those with poor blood pressure control or severe angina symptoms, physicians may recommend increasing the dose to two tablets per administration. However, this should be decided based on the patient's individual condition and response to the medication. Patients should also monitor their response after taking the medication and promptly seek medical attention and inform their doctor if adverse effects such as hypotension, edema, or tachycardia occur.
