Calan SR is a medication that belongs to the calcium channel blocker class of drugs. It is used for the treatment of high blood pressure, angina (chest pain), and certain heart rhythm disorders. Calan SR is only available with a prescription from a licensed healthcare provider and is not recommended for people under 18 years of age. In this article, we’ll explore Calan SR’s uses, benefits, side effects, and warnings.
Uses
Calan SR (verapamil hydrochloride) is used primarily to treat high blood pressure (hypertension). It works by relaxing the blood vessels, which in turn lowers blood pressure. Calan SR is also used to treat angina (chest pain) caused by coronary artery disease. It can help alleviate symptoms such as discomfort or pressure in the chest, as well as shortness of breath, sweating, and/or nausea.
In addition to treating high blood pressure and angina, Calan SR is sometimes used to control certain heart rhythm disorders, such as atrial fibrillation or atrial flutter. It can also be used to prevent chest pain associated with exercise (exercise-induced angina).
Benefits
Calan SR’s primary benefit is its ability to lower blood pressure and alleviate symptoms of angina. When prescribed and taken correctly, Calan SR can help prevent serious long-term health complications associated with high blood pressure, such as stroke, heart attack, and kidney damage.
For people with angina, Calan SR can help improve their quality of life by reducing the frequency and severity of chest pain episodes. It can also help improve their overall physical performance by enabling them to engage in activities that may have previously caused discomfort or pain.
Finally, for people with certain heart rhythm disorders, Calan SR can help control heart rate and improve overall heart function.
Side Effects
Like all medications, using Calan SR can come with some side effects. The most common side effects of Calan SR include:
- Constipation or diarrhea

If you experience any of these serious side effects, seek medical attention right away.
Warnings

It should also not be used in people with low blood pressure or heart conditions that could be exacerbated by decreased heart rate.
