Why is this medication prescribed?

High blood pressure is treated with isradipine. Isradipine belongs to the group of drugs known as calcium channel blockers. Because the blood arteries are relaxed, your heart does not have to work as hard to pump as hard.

High blood pressure is a common illness that, if left untreated, can harm the kidneys, brain, heart, blood vessels, and other organs. Heart disease, a heart attack, heart failure, a stroke, renal failure, eyesight loss, and other issues may result from damage to these organs. Making lifestyle modifications will help you control your blood pressure in addition to taking medication. These adjustments include quitting smoking, drinking alcohol in moderation, eating a diet low in fat and salt, keeping a healthy weight, and exercising for at least 30 minutes most days.

How should this medicine be used?

Isradipine is available as a pill to swallow. The pill is typically taken twice daily. Use isradipine at around the same time(s) every day to make it easier for you to remember to take it. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Isradipine should be taken as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.

Although it doesn’t treat high blood pressure, isradipine manages it. Even if you feel good, keep taking isradipine. Without consulting your doctor, do not discontinue taking isradipine.

Other uses for this medicine

Ask your doctor or pharmacist for more details if you’re interested in using this drug for any other conditions.

What special precautions should I follow?

Before taking isradipine,

  • If you have an allergy to isradipine, any other drugs, or any of the substances in isradipine capsules, inform your doctor right away. Get a list of the components from your pharmacist.
  • Inform your doctor and pharmacist about all prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products that you are now taking or intend to use. Mention any of the following: cimetidine (Tagamet), fentanyl (Duragesic), beta-blockers and diuretics (‘water pills’) for treating high blood pressure and cardiac problems, ranitidine (Zantac), and rifampin (Rifadin, Rimactane).
  • Inform your physician if you now have or have ever had renal, liver, or cardiac illness.
  • Inform your doctor if you are expecting, intend to get pregnant, or are nursing a baby. Call your doctor if you conceive while taking isradipine.
  • You should let your doctor or dentist know if you are taking isradipine if you are undergoing surgery, including dental surgery.

What special dietary instructions should I follow?

Consult your doctor before consuming grapefruit or grapefruit juice while taking isradipine.

Before using potassium-containing salt replacements, consult your doctor. If your doctor advises a low-salt or low-sodium diet, strictly follow the instructions.

What should I do if I forget a dose?

If you miss a dosage, take it as soon as you recall. If the next dose is soon due, skip the missed one and carry on with your regular dosing plan. To make up for a missing dose, do not take a second one.

What side effects can this medication cause?

There may be adverse consequences from isradipine. If any of these symptoms are severe or do not go away, let your doctor know right once:

  • Headache
  • Feeling unsteady or lightheaded
  • Flushing
  • Rapid heart rate
  • Extreme fatigue

  • Breathing or swallowing challenges
  • Fainting

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at for additional information.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Moreover, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

Keep all of your appointments with your physician and the lab. You should routinely monitor your blood pressure to see how isradipine affects you.

No one else should take your medication. Any queries you may have regarding medication refills should be directed to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
