FAQ

Which Verapamil strengths and pack sizes can I order?

Verapamil comes as 40mg and 120mg tablets. Packs range from 30 to 480 tablets, depending on strength. Larger packs cost less per tablet.

How can I pay for Verapamil and have it delivered to Hong Kong?

Card or crypto: Visa, Mastercard or American Express on an encrypted page that keeps your card number off our servers, or Bitcoin or Ethereum. The tablets then travel in a plain box by tracked courier, which takes 5 to 9 business days.

Which brand names does verapamil have?

Brand names for verapamil include Calan SR, Isoptin, Securon, Verelan and Cordilox. Verapamil tablets are a pure generic verapamil product and are not any of those brands. Here, verapamil can also be bought online as generic Isoptin.

How often should I take verapamil 40mg?

Short-acting verapamil at 40mg or 120mg means three or four tablets across the day. Slow-release verapamil is a separate product, dosed once or twice daily. Whichever you use, choose times you can repeat from one day to the next.

Can I drink grapefruit juice with verapamil?

Better not to. Grapefruit blocks an enzyme that breaks verapamil down, so more of the drug stays in your system and its effect can become too strong: blood pressure dropping too low, or the pulse slowing more than it should. Skip grapefruit and grapefruit juice while you are taking it.

Does verapamil cause constipation?

Yes, it is the side effect people mention most. Smooth muscle in the bowel wall relaxes along with the muscle in blood vessels, so stools move slowly and turn hard. Extra water and more fibre in meals usually make it manageable.

What is the difference between verapamil and amlodipine?

Both are calcium channel blockers, but they are different types. Verapamil slows the heart's electrical conduction and can slow the pulse, which is why it is used for angina and some irregular rhythms as well as for blood pressure. Amlodipine mainly widens the arteries and has little effect on heart rate.

How should I store verapamil tablets?

A drawer or shelf indoors works well; a hot car or a sunny windowsill does not. Keep the tablets in their blister strips or bottle, and replace any that have gone soft or changed colour. Refrigeration is unnecessary.

About Verapamil

What verapamil tablets do

Verapamil is used in three situations: high blood pressure, angina (chest pain that comes on when the heart is short of oxygen) and fast or irregular rhythms such as atrial fibrillation. It is a calcium channel blocker, and each use traces back to the same action. Arteries relax, so the heart pumps against less resistance; the coronary arteries widen, so the heart muscle gets more blood and oxygen; and the electrical signals that set the pulse are slowed. The 40mg and 120mg tablets sold here are the short-acting form, and the lower strength is also the one used for rhythm control.

Taking 40mg or 120mg through the day

These are short-acting tablets, so the day's dose is split into three or four tablets, swallowed with water across the hours you are awake and at similar times from one day to the next. Verapamil holds blood pressure and heart rhythm in check without curing the cause, which is why it goes on daily, even on days you feel fine. Stopping abruptly can bring angina back or set off a fast heartbeat.

Side effects

The side effect most people meet is constipation: the muscle in the bowel wall relaxes along with the muscle in the arteries, and the gut slows down. Dizziness, headaches, flushing, swollen ankles and a slower pulse can also appear. A very slow pulse, severe breathlessness or fainting needs urgent treatment.

Grapefruit and other interactions

Grapefruit and grapefruit juice slow the body's breakdown of verapamil. Levels can climb, blood pressure can drop too far and the pulse can slow excessively, so it is simplest to leave grapefruit out of your diet while taking it. St John's wort and cimetidine, a medicine for heartburn and ulcers, also alter how the body handles verapamil. Taken with beta-blockers, verapamil can slow the heart more than either drug would alone, and it raises the blood levels of some statins, including simvastatin and lovastatin, which increases the chance of muscle side effects.

Verapamil or Isoptin?

Isoptin holds the same ingredient under a brand name, in 40mg, 120mg and 240mg tablets. The verapamil tablets on this page stop at 120mg, so for the 240mg strength look at Isoptin.
