Nisoldipine is used to treat high blood pressure. Nisoldipine is in a class of medications called calcium channel blockers. It works by relaxing your blood vessels so your heart does not have to pump as hard.
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

Dosage Of Nisoldipine
Nisoldipine comes as an extended-release (long-acting) tablet to take by mouth. It is usually taken once a day. To help you remember to take nisoldipine, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nisoldipine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole; do not split, chew, or crush them.
Nisoldipine controls high blood pressure but does not cure it. Continue to take nisoldipine even if you feel well. Do not stop taking nisoldipine without talking to your doctor.
Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to nisoldipine.
The extended-release tablet does not dissolve in the stomach after being swallowed. It slowly releases medicine as it passes through your small intestines. It is not unusual to see the tablet shell in the stool.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
