Calan is a calcium channel blocker medication that is used to treat high blood pressure, angina (chest pain), and certain heart rhythm disorders. Its generic name is verapamil hydrochloride. Calan works by relaxing the blood vessels, improving blood flow and reducing the workload on the heart.
Calan is available in various forms, including immediate-release tablets, extended-release tablets, and sustained-release capsules. It is typically taken orally and the dosage may vary depending on the condition being treated and the patient’s response to the medication.
Do’s and Don’ts
Before taking Calan, it is important to inform your healthcare provider about any allergies, medical conditions, or medications you are currently taking. This medication should not be used if you have a known hypersensitivity to verapamil or any of its components.
Calan should not be taken by individuals who have certain heart conditions such as second- or third-degree heart block, severe left ventricular dysfunction, or cardiogenic shock. Additionally, it should not be used by patients with low blood pressure (hypotension) or a recent heart attack.
It is important to follow the prescribed dosage and schedule while taking Calan. Do not abruptly stop taking the medication without consulting your doctor, as this may lead to a sudden increase in blood pressure or chest pain.
Potential Side Effects
Like any medication, Calan may cause certain side effects. Common side effects may include constipation, dizziness, headache, and irregular heartbeat. These side effects are generally mild and may subside with continued use of the medication.
Some individuals may experience more serious side effects such as swelling of the ankles or feet, shortness of breath, fainting, or signs of liver problems. If any of these symptoms occur, it is important to seek immediate medical attention.
How to Take It
Calan should be taken exactly as prescribed by your doctor. It is typically taken with or without food, depending on the formulation. It is important to swallow the tablet or capsule whole and not to crush, chew, or break it.
If you miss a dose of Calan, take it as soon as you remember. However, if it is close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
An overdose of Calan can be dangerous. Symptoms of an overdose may include severe dizziness, fainting, slow heartbeat, or difficulty breathing. If you suspect an overdose, seek immediate medical attention or contact a poison control center.
Understanding Drug Interactions
Calan may interact with other medications, resulting in potentially harmful effects. Inform your healthcare provider about all the medications you are currently taking, including prescription drugs, over-the-counter medications, and herbal supplements.
Calan may interact with medications such as beta-blockers, statins, antiarrhythmic drugs, and certain antibiotics. These interactions can affect the effectiveness and safety of both medications. It is important to follow your doctor’s advice and monitor for any potential interactions.
