What is isosorbide mononitrate 60 mg tablet (ER)?
Isosorbide mononitrate (often written as isosorbide mononitrate ER or “ER 60 mg”) is a long-acting nitrate medicine used to prevent angina (chest pain) in people with coronary artery disease. The “ER” means the tablet releases the drug over time rather than all at once.
How should people usually take a 60 mg ER tablet?
Dosing depends on the specific product and your clinician’s plan. In general, long-acting isosorbide mononitrate tablets are taken on a set schedule (often once daily, or sometimes split depending on the regimen), and they should be swallowed whole. Do not crush or chew ER tablets unless the prescribing information says it’s allowed.
What does it do in the body?
Nitrates like isosorbide mononitrate relax blood vessels, improving blood flow and reducing the heart’s workload. This helps prevent angina attacks.
Common side effects people ask about
Common side effects include headache, dizziness, flushing, and lightheadedness. These can be more noticeable when starting or when the dose changes.
What drugs can it not be taken with?
Isosorbide mononitrate should not be taken with medicines for erectile dysfunction that contain PDE-5 inhibitors (such as sildenafil, tadalafil, or vardenafil), because the combination can cause dangerous blood-pressure drops.
When should you seek urgent help?
Get emergency care if you have severe dizziness or fainting, symptoms of a very low blood pressure episode, or new/worsening chest pain that doesn’t follow your usual plan.
