Uses
- Preventing angina attacks (chest pain from narrowed heart arteries) – the sustained-release tablet is taken regularly, not for an attack that has already started.
- Long-term treatment of chronic stable angina alongside aspirin, statins and beta blockers.
- Sometimes used after a heart attack or in heart failure to reduce the heart's workload, under a cardiologist.
How to take it
Swallow the sustained-release tablet whole with water, usually twice a day as your cardiologist directs – do not crush, chew or break it, because that releases the whole dose at once. Taking it with food can reduce the headache that is common in the first days. Your doctor will usually space the doses so that you have a nitrate-free period of several hours each day, since the body gets used to nitrates if they are present round the clock. This tablet is NOT for a sudden attack: for chest pain use the quick-acting sublingual tablet or spray your doctor gave you, sit down, and call for emergency help if pain is not better within a few minutes of the second dose. Do not stop sustained-release nitrates suddenly.

Interactions

- Alcohol and sedatives increase dizziness and fainting.
- Medicines that cause dry mouth (some antihistamines and antidepressants) can stop sublingual tablets dissolving properly.
Frequently asked questions
What is Nitrocontin 2.6 used for?
Nitrocontin 2.6 is a controlled-release nitroglycerin (glyceryl trinitrate) tablet. It is taken regularly to prevent angina attacks by relaxing the heart's blood vessels and reducing its workload.
Can I take Nitrocontin during a chest pain attack?
No. The sustained-release tablet works slowly and is for prevention. For an attack, use the fast-acting sublingual GTN tablet or spray your doctor prescribed, and call for emergency help if pain does not settle after the second dose.
Nitrocontin vs Sorbitrate – what is the difference?
Nitrocontin contains nitroglycerin in a slow-release form for regular use. Plain Sorbitrate is isosorbide dinitrate, a related nitrate often used under the tongue for quick relief; GTN Sorbitrate CR is the slow-release nitroglycerin version. Your cardiologist decides which you need.
Why does Nitrocontin cause headaches?
Nitrates widen blood vessels, including those in the head, which causes headache in the first days. It usually fades as your body adjusts; paracetamol can help. Tell your doctor if it is severe or persistent.
Can I take Viagra or Manforce with Nitrocontin?
Never. Sildenafil, tadalafil and similar medicines with any nitrate can cause a sudden, life-threatening fall in blood pressure. Tell every doctor you see that you take a nitrate.
Can I crush or break a Nitrocontin tablet?
No. Breaking or crushing a controlled-release tablet releases the full dose at once, which can cause severe dizziness and fainting. Swallow it whole.
Can I drink alcohol with Nitrocontin?
Avoid it. Alcohol and nitrates together drop blood pressure sharply and can make you faint.
Why is there a gap between my Nitrocontin doses?
Nitrates stop working as well if they are in the body all the time. Doctors deliberately schedule the doses to leave a nitrate-free period each day so the medicine keeps protecting you.
Is Nitrocontin a prescription medicine?
Yes. It is a Schedule H medicine and should be taken only under a cardiologist's supervision, along with the other heart medicines you have been prescribed.
