What you will receive

Tenormin is the originator brand name, made by AstraZeneca. We use it to identify the medicine; the pack you receive is a generic equivalent, not the original Tenormin.

  • The same active ingredient (Atenolol) at the same strength.
  • The exact brand supplied depends on what is in stock when your order ships.

FAQ

Which Tenormin strengths and pack sizes can I order?

25mg, 50mg and 100mg tablets, in packs from 14 up to 350 depending on the strength. They are generic atenolol rather than the original Tenormin. The price per tablet, in Hong Kong dollars, drops in the biggest packs.

Can I track a Tenormin order to Hong Kong?

Yes, if you choose tracked courier, which takes 5 to 9 business days and includes online tracking. Standard airmail takes 14 to 21 business days and is untracked. Tracking details appear on the tracking page, and a parcel that goes missing is sent again free.

What are the alternative names for Tenormin and atenolol?

Tenormin is a brand name of atenolol, which is also sold as Aten and Tenopress. Here, atenolol can be bought online as generic Tenormin, and also as atenolol tablets. These are generics, not the original brand.

Is Tenormin the same as atenolol?

The medicine is the same. The pack sold as Tenormin holds generic atenolol rather than the original branded tablets, and the other option is the same drug under the ingredient's own name. Both are 25mg, 50mg and 100mg tablets, so the difference is the name on the box.

How long does Tenormin take to work?

The drop is gradual rather than instant. Blood pressure and angina settle over the first one to two weeks of steady daily dosing, which is why the tablets are taken at the same time each day. Skipping doses gives the pressure a chance to creep back up.

Can I stop Tenormin suddenly?

Atenolol is not stopped in one step. Cutting it out suddenly can make angina worse or set off a fast, irregular heartbeat, so the dose is reduced in stages, usually over a week or more. A slower drop lets the heart adjust as the blocking effect wears off.

Missed a Tenormin tablet?

A late tablet is fine if the next one is still some hours away. When the next dose is close, skip the late one and return to the usual pattern. Two tablets together make the pulse and pressure drop further than intended.

Will Tenormin change my heart rate during exercise?

Yes. Atenolol caps how fast the heart can beat, so a hard session that once pushed your pulse to a high number will now peak well below it. That is the medicine at work rather than a loss of fitness; judge effort by breathing and how the session feels.

About Tenormin

What Tenormin tablets are for

The tablets hold atenolol, a beta-blocker. Atenolol is used for high blood pressure and for angina — the chest pain brought on by exertion or stress. It works by slowing the heart and letting blood vessels widen, so the heart meets less resistance and uses less oxygen. Blood pressure comes down, and angina is less likely to flare. Atenolol is also used to improve survival after a heart attack.

Taking atenolol

One or two tablets a day at regular times is the usual pattern. Treatment often begins with a 25mg or 50mg tablet, and the dose goes up if readings stay high. Atenolol keeps blood pressure and angina in check without curing either, and the full effect can take one to two weeks of daily use to appear.

Side effects worth knowing

Tiredness, dizziness when standing up and cold hands and feet are common early on. Nausea, diarrhoea, a dry mouth or dry eyes and low mood turn up too, and most of these settle as the body adjusts. Wheezing or shortness of breath, fainting, swelling of the hands, feet or ankles, unexplained weight gain, or a pulse that turns rapid, pounding or irregular needs urgent treatment. The shakiness and racing pulse that normally announce low blood sugar can be muted by atenolol, so a hypo may creep up with little warning.

What it interacts with

Medicines that slow the heart add to atenolol's effect, and verapamil and diltiazem are the pair to know about — with atenolol on board, the pulse can drop too far. Other treatments for high blood pressure can push readings lower than expected when they are combined with it.

Tenormin or plain atenolol?

Both packs contain atenolol at 25mg, 50mg and 100mg in tablet form. The difference is the name on the box: the tablets sold as Tenormin are generic atenolol rather than the original branded product, while Atenolol is sold under the ingredient's own name. Strengths and the daily routine match either way.
