Imdur 60mg is known as Monodur internationally


What is Imdur?

Imdur is an oral tablet made up of a nitrate drug called isosorbide mononitrate. We carry this medication in both the brand choice and generic alternative in 30mg and 60mg!

What is Imdur used for?

Imdur is a medication used to prevent the chest pain (angina) that patients with coronary artery disease (a heart condition) experience. Coronary artery disease, which can sometimes be referred to as atherosclerotic heart disease, is a buildup of plaque in your coronary arteries. Your coronary arteries are important as they are the blood vessels in charge of carrying the oxygen-rich blood to your heart. These arteries are usually smooth and elastic-like; however, when a person has coronary artery disease, they become stiff and narrow, slowing the blood flow to the heart muscle, causing health issues. In the case of the plaque breaking off, one may experience a heart attack or sudden cardiac death.

What does Imdur do?

Imdur (isosorbide mononitrate) is effective in preventing angina in coronary artery disease patients because it is able to relax and widen the blood vessels, allowing the blood to flow more easily and smoothly.

Take this medication exactly how your doctor has directed you too. You can find the directions written on your prescription label or you can call your doctor if you are unsure.

It is recommended you stay in a sitting position when taking the medication to avoid dizziness or fainting.

Do not crush, chew, or break this tablet; swallow whole with a glass of water.

Use this medication regularly in order for it to be effective. Keep a reminder written in the calendar or use a pillbox to help you remember.

Do not suddenly stop taking Imdur. Doing so could cause a severe angina attack.

Store Imdur at room temperature. Keep protected from moisture, heat and light. Keep the lid closed tightly shut when you are not using the medication.


You should not combine Imdur with medication that treats erectile dysfunction. This includes Viagra, Cialis, Levitra, Stendra, Staxyn, sildenafil, avanafil, tadalafil, and vardenafil. Mixing Imdur with any of these listed drugs may cause a sudden increase in blood pressure. Speak to your doctor about other medications that may interact with Imdur.

Do not stop taking this medication without being directed on how to by your doctor. Suddenly stopping this treatment may cause a severe angina attack.

If you are allergic to isosorbide mononitrate, isosorbide dinitrate, or nitroglycerin or if you have early signs of a heart attack (such as (chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating) you may want to find an alternate medication. Consult your doctor about a safer medication.

You may need a dose adjustment if you have congestive heart failure, kidney disease, or if you have low blood pressure. Consult your doctor about your medical conditions and how they may interact with Imdur before starting treatment.

Tell your doctor if you are pregnant or plan on becoming pregnant; Imdur may not be safe for your unborn baby. It may not be safe to breastfeed. Consult your doctor if you have a breastfeeding infant.

Side Effects

Common side effects of Imdur (isosorbide mononitrate) may include:

headache; or flushing (warmth, redness, or tingly feeling).

The above side effects should not alarm you.

Serious side effects of Imdur (isosorbide mononitrate) may include:

a light-headed feeling, like you might pass out; worsening angina pain; fast or slow heart rate; or pounding heartbeats or fluttering in your chest.

If you have any of the above side effects, contact your doctor right away.


What is the recommended dose for an adult with angina due to coronary artery disease?

An adult with angina due to coronary artery disease would take 30-60mg once a day; for best effect, take the dose in the morning. Do not exceed more than 240mg once a day. If you are elderly, consider starting on the lower side of the recommended dose.

What should I avoid while using Imdur?

It is recommended you avoid driving or doing activities that require your full attention until you know how this medication affects you. It may cause dizziness or impaired thinking. To avoid these effects, avoid standing up suddenly or consuming alcohol.

Will Imdur be effective in treating an angina attack that has already started?

Unfortunately, Imdur is used to prevent angina attacks from occurring but won’t help an attack that has already begun. You may want to consider consulting your doctor about a ranolazine (also known as Ranexa; available at MyDrugCenter) prescription, or you can buy aspirin over-the-counter for relief of an acute attack.

What is the best way to store this medication?

Store in room temperature away from moisture, heat and light. Keep away from children and pets, and keep the lid closed tightly shut when you are not using the medication.
