If you’ve been prescribed Imdur, you’re probably wondering what it actually does and how to use it without a hassle. In short, Imdur is the brand name for isosorbide mononitrate, a pill that helps prevent chest pain (angina) by keeping your blood vessels relaxed.
Imdur belongs to a class of drugs called nitrates. It works by widening the veins so blood can flow back to the heart more easily. This reduces the workload on your heart and stops the painful tightening that comes with angina. Unlike nitroglycerin, which you might take right before an attack, Imdur is taken every day to stop attacks from happening in the first place.
The usual dose starts low – often one tablet a day – and your doctor may increase it if needed. Take it at the same time each day, preferably with food to avoid stomach upset. Swallow the tablet whole; don’t crush or chew it because that can cause a sudden drop in blood pressure.
Alcohol can make Imdur’s blood‑pressure‑lowering effect stronger, so limit drinks while you’re on this medication. If you feel dizzy, light‑headed, or notice a rapid heartbeat, sit down right away and tell your doctor.
One common mistake is forgetting to take the pill and then taking two at once to “catch up.” That can lead to dangerous low blood pressure. If you miss a dose, just skip it and continue with your regular schedule.
Imdur may interact with other meds such as certain antibiotics (e.g., erythromycin) or medications for erectile dysfunction. Always share your full medication list with your healthcare provider so they can spot any risky combos.
Side effects are usually mild. The most frequent ones include headache, flushing, and a feeling of warmth. If a headache becomes severe or lasts more than a few days, let your doctor know – they might adjust the dose.
Rarely, people develop a rash or an allergic reaction. Seek medical help right away if you notice swelling, itching, or trouble breathing.
Because Imdur lowers blood pressure, it’s important not to stand up too quickly from sitting or lying down. Moving slowly can keep you from feeling faint.
If you’re planning surgery or a dental procedure, tell the surgeon that you’re on Imdur. They may ask you to stop the drug for a short period to avoid complications.
For anyone who’s new to Imdur, keeping a simple log can help. Write down the time you take your pill and any symptoms you notice. This record makes it easier for your doctor to fine‑tune the dose.

Bottom line: Imdur is a daily preventive tool for angina. Take it as directed, watch for dizziness or headaches, avoid alcohol excess, and keep your doctor in the loop about other drugs you use. Doing so will help you stay active without worrying about chest pain.
