Frequently Asked Questions about Nifedipine

1. Can I take Nifedipine at night?

You can take Nifedipine at any time of the day. It is helpful to have the medicine at the same time every time. Your doctor can recommend the best time to take the drug. It is best consumed one or two hours before a meal. Do not crush or chew the tablets but swallow the medicine.

2. How long does Nifedipine stay in your system?

Some experts believe that Nifedipine stays in the system for seven hours. After you stop the medicine, traces are still present in urine and feces. Do not stop Nifedipine (as it may increase your blood pressure and the risk of a stroke and heart attack) unless your doctor suggests otherwise.

3. How long does it take for Nifedipine to work?

Nifedipine starts working from the day you start taking it. However, it takes a few weeks before it starts to take effect. Studies show that Nifedipine is absorbed quickly in the blood. It is short-acting and takes thirty minutes to peak when taken orally. Consume the medicine exactly as directed by your doctor.

4. Is Nifedipine a beta-blocker?

Nifedipine is a beta-blocker that helps to lower high blood pressure. Beta-blockers treat several medical conditions like heart failure and migraine. The drug belongs to a class of medications called calcium-channel blockers (that helps to dilate arteries and makes it easier for the heart to pump blood).

5. Does Nifedipine lower heart rate?

Nifedipine relaxes the blood vessels and increases the blood supply and oxygen to the heart. It controls the movement of calcium into the cells of the heart. Nifedipine can reduce the amount of work that the heart must do and lowers the heart rate. You should take the medicine at the same time and the same dosage, as directed by your physician, every day.

6. Does Nifedipine make you pee?

One of the possible side effects of Nifedipine is that you may need to urinate more than usual. Experts suggest that it does not affect the pressure in the bladder or urethra. If you have any unusual symptoms that are affecting your day-to-day routine, let your doctor know immediately.

7. How to stop taking Nifedipine?

Never stop taking Nifedipine abruptly. It can increase your blood pressure or increase the risk of heart attack or stroke. In case you feel that Nifedipine is causing you discomfort, let your doctor know. Your doctor can prescribe a different medicine for your medical concern.

8. Is Nifedipine a diuretic?

Nifedipine is not a diuretic. It comes from a class called calcium channel blockers or calcium antagonists. Nifedipine is used to treat high blood pressure and chest pain or angina. Doctors also recommend the medicine to cure Raynaud’s phenomenon (which causes discoloration in toes and fingers).

9. Is Nifedipine a blood thinner?

The medicine is not a blood thinner. Blood thinners or anticoagulants contain chemical components that prevent blood coagulation and prolongs blood clotting time. Nifedipine is a calcium channel blocker that helps to lower high blood pressure. If you are already taking blood thinners, let your doctor know.

10. Is Nifedipine safe to take?

Nifedipine is a safe medicine that causes few side effects. The medication is only available with a prescription. Never stop having the drug on your own. In case you miss a dose, never take a double dosage. If you have severe side effects, alert your doctor immediately.
