Calan SR (verapamil) is a calcium channel blocker useful in treating several heart- and blood-related ailments. The medication slows the heartbeat and relaxes the heart and blood vessels, reducing blood pressure, decreasing the heart's workload, and improving blood flow.

The SR in this product stands for sustained release, meaning it's only taken once or twice per day. Patients can also buy Calan SR as regular Calan tablets, taken two or three times per day.

Calan SR tablets are suitable for patients age 16 and up.

When to Buy Calan SR

This medication provides several benefits to the cardiovascular system; it reduces blood pressure, improves blood flow, and reduces the heart's workload. Patients usually buy Calan SR to treat:

• Hypertension (high blood pressure)
• Supraventricular tachycardia (rapid heartbeat)
• Angina (chest pain)
• Migraine headaches
• Cluster headaches

Calan SR has a direct effect on hypertension and supraventricular tachycardia; slowing and stabilizing the heart while reducing elevated blood pressure. In other cases---angina, migraines, and cluster headaches---it is a preventative treatment; it reduces the frequency and severity of angina or headaches, perhaps eliminating them completely.

Note that it takes several weeks of treatment to see full benefit, and Calan SR will not address flare-ups in which pain is actually being experienced. Rescue treatments---like nitroglycerin or triptans---should still be utilized as-needed when an episode is happening.

How to Take Calan SR

Treatment with Calan SR is quite similar in all cases; the medication is taken daily over the long term. Other medications may or may not be involved. Personal variables, such as age and weight, can influence dosage levels, as will patient response to treatment.

Treatment usually starts the same:

• Take 180 mg per day in the morning.
• Tablets should be swallowed whole and taken with food.

The initial dose may need to be adjusted; effects should be checked after one week of treatment for hypertension, three to four weeks for other conditions. If adjustments are needed there are several options:

• Take 240 mg once per day in the morning; or
• Take 180 mg in the morning and 180 mg in the evening; or
• Take 240 mg in the morning and 120 mg in the evening; or
• Take 240 mg every 12 hours.

Doses greater than 240 mg per day are typically reserved for heart conditions. For migraines and cluster headaches treatment is more likely 240 mg per day or less, though there may be exceptions. Patients taking Calan SR will likely need frequent heart and blood pressure tests until the ideal dosage is established, regardless of why it's being taken.
