Taking nifedipine extended-release tablets for constipation can be improved by changing to other antihypertensive drugs, or by dietary modification or medication. Clinically, nifedipine extended release tablets belong to calcium channel blocker drugs. Because of the effects of blocking calcium channels, dilating blood vessels and inhibiting the heart muscle, they are usually used in the treatment of hypertension, angina pectoris, arrhythmia and other diseases. However, symptoms such as flushing, headache, dizziness, nausea and constipation may occur after taking the drug. If constipation occurs after taking the drug, it is recommended to change the antihypertensive drugs such as enalapril, chlorosartan, hydrochlorothiazide and sodium nitroprusside. In daily life, it is recommended to consume more high-fiber vegetables and fruits, so as to promote intestinal peristalsis and change the nature of feces. If necessary, follow the doctor’s advice to choose lactulose, polyethylene glycol and other drug treatment. Nifedipine is usually contraindicated in people who are allergic to nifedipine, breastfeeding women, patients with cardiogenic shock, and when taking rifampicin. It is usually used with caution in heart failure and severe aortic stenosis with hypotension. Blood pressure should be monitored to avoid hypotension. The above drugs should be used under the supervision of a doctor. If you need to take nifedipine controlled-release tablets because of your condition, it is recommended that you take the dosage after a comprehensive assessment of your condition by your doctor.
