Uses of Imdur Tablet PR

Benefits of Imdur Tablet PR

Treatment of Angina (heart-related chest pain)
Angina is chest pain caused by reduced blood flow to the heart muscle, usually due to narrowed coronary arteries. Imdur 60mg Tablet PR helps by relaxing and widening blood vessels, which improves blood flow and oxygen supply to the heart. This helps relieve chest discomfort and reduces the risk of angina attacks.

Common side effects of Imdur
  • Headache
  • Flushing (sense of warmth in the face, ears, neck and trunk)
  • Upper respiratory tract infection

  • Diarrhea

How to use Imdur Tablet PR

Use it as advised by your doctor or check the label for directions before use. Imdur 60mg Tablet PR may be taken with or without food.

How Imdur Tablet PR works

Imdur 60mg Tablet PR is a nitrate. It dilates peripheral arteries and veins. Dilation of the veins promotes peripheral pooling of blood and decreases venous return to the heart, thereby reducing the workload of the heart. As a result, the heart muscle does not need as much blood and oxygen supply.

Frequently asked questions

Imdur 60mg Tablet PR is a medicine used to help prevent angina, which is chest pain caused by reduced blood flow to the heart. It works by relaxing and widening the blood vessels, allowing blood to flow more easily to the heart and reducing the heart’s workload. This helps prevent episodes of chest pain during daily activities. However, Imdur 60mg Tablet PR is not intended to relieve sudden angina attacks once they have started. Because the medicine can lower blood pressure, some people may feel dizzy or light-headed, especially when standing up quickly.
Imdur 60mg Tablet PR may affect heart rate in some people. Because the medicine lowers blood pressure by widening blood vessels, the body may respond by increasing the heart rate (reflex tachycardia) in some cases. These changes are usually mild, but if you notice a significant change in heart rate or feel unwell after taking the medicine, you should consult your doctor.
Imdur 60mg Tablet PR may begin working the same day you start taking it, but its main purpose is to prevent angina over time rather than provide immediate symptom relief. The medicine releases its active ingredient slowly to maintain a steady protective effect. Because it works gradually, you may not feel any immediate difference even though it is helping protect your heart.
Imdur 60mg Tablet PR is usually taken once daily in the morning unless your doctor recommends a different schedule. Taking it at the same time every day helps maintain a consistent effect in the body. Doctors often schedule the dose in a way that allows a daily nitrate-free interval, which helps prevent the body from becoming tolerant to the medicine. If your doctor prescribes it twice daily, the doses are usually spaced several hours apart.
If you forget to take a dose of Imdur 60mg Tablet PR, take it as soon as you remember, as long as it is within about 12 hours of the scheduled time. If more than 12 hours have passed, skip the missed dose and take the next dose at the usual time. Do not take two doses at the same time to make up for a missed one.
Headache is one of the most common side effects of Imdur 60mg Tablet PR. Some people may also experience flushing, dizziness, or symptoms of low blood pressure. These effects occur because the medicine widens blood vessels. Headaches often improve as the body adjusts to the medication. If headaches are severe or persistent, consult your doctor.
You should not stop taking Imdur 60mg Tablet PR without consulting your doctor. Stopping the medicine suddenly may increase the risk of angina attacks. If you have concerns about side effects or the need for the medication, speak with your doctor before making any changes.
Taking more than the recommended dose of Imdur 60mg Tablet PR may cause symptoms such as a severe throbbing headache, flushing of the skin, sweating, chills, nausea, vomiting, or a rapid heartbeat. If an overdose is suspected, seek emergency medical help immediately and contact your doctor.
While taking Imdur 60mg Tablet PR, avoid using medicines for erectile dysfunction such as sildenafil, tadalafil, or vardenafil unless your doctor specifically approves them. Combining these medicines can cause a dangerous drop in blood pressure. Alcohol should also be limited because it may increase dizziness or light-headedness. Rise slowly from sitting or lying positions to reduce the risk of fainting.
Imdur 60mg Tablet PR does not usually cause direct sleepiness. However, some people may feel dizzy or tired due to its blood pressure–lowering effect. If you feel faint or unsteady after taking the medicine, avoid driving or operating machinery until you feel better. If these symptoms persist, consult your doctor.
Imdur 60mg Tablet PR is not commonly known to directly harm the kidneys or liver. However, if blood pressure drops too low or if dehydration occurs, kidney function may be affected in some people. Maintaining adequate fluid intake and following your doctor’s advice can help reduce this risk. If you notice reduced urination, repeated dizziness, or unusual symptoms while taking Imdur 60mg Tablet PR, consult your doctor.
