Why is this medication prescribed?
Verapamil is used to manage angina and treat high blood pressure (chest pain). To prevent and cure irregular heartbeats, the immediate-release tablets can be taken on their own or in combination with other medicines. Verapamil belongs to the group of drugs known as calcium-channel blockers. In order to reduce the heart’s workload, it operates by relaxing the blood arteries. Moreover, it enhances the heart’s blood and oxygen flow while decreasing electrical activity to regulate heart rate.
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?
Verapamil is a medication that can be taken orally as a tablet, an extended-release (long-acting) tablet, or an extended-release (long-acting) capsule. The typical dosage for the standard tablet is three to four times per day. It is typical to take the extended-release pills and capsules once or twice a day. Take verapamil every day at around the same time(s). Certain verapamil medications need to be taken in the morning, while others are best taken at night. What time of day is best for you to take your medication? Consult your doctor. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Provide verapamil as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.
The extended-release pills and capsules should be taken whole. Avoid chewing or crushing them. Given that the directions differ depending on the product, ask your pharmacist if you can divide the tablets in half.
You can gently open the extended-release capsule and pour the entire contents into a spoonful of applesauce if you are unable to swallow them. It should not be heated, and the applesauce should be soft enough to be ingested without chewing. Drink a glass of lukewarm water after swallowing the applesauce without chewing to ensure that all of the medication has been absorbed. Never keep the combination on hand for later usage.
Verapamil will likely be prescribed to you at a low dosage by your doctor, who will then likely progressively raise it.
Verapamil regulates angina, hypertension, and arrhythmias but does not treat them. Verapamil should be taken even if you feel fine. Without first consulting your doctor, do not discontinue taking verapamil.
Other uses for this medicine
Verapamil is occasionally used to treat several additional cardiac issues. The dangers of using this drug for your illness should be discussed with your doctor.
