Nifedipine can generally be used for long-term use under the supervision of a physician and as directed by the physician. Nifedipine, as a calcium antagonist, is indicated for the treatment of hypertension and coronary heart disease (including many types of angina). Because the indications are chronic, regular long-term use of the drug may improve the prognosis of patients, so the drug can be used for long-term use under the supervision of a physician. Note that the drug is contraindicated in people who are allergic to the product, and there are also instructions suggesting that pregnant women, pregnant women, etc. belong to the prohibited group. Adverse reactions such as peripheral edema, dizziness, headache, nausea, fatigue, facial flushing, transient hypotension and other adverse reactions may occur after the use of the drug. Specific drug use should follow the doctor’s instructions, not unauthorized use of drugs.
