About Isonitrate 30mg Tablet SR

Isonitrate 30mg Tablet SR is a prescription medicine used to prevent chest pain, which is also known as angina, in people with heart disease. It works by relaxing and widening your blood vessels, allowing blood and oxygen to flow more easily to your heart. It is important to know that this medicine is used to prevent chest pain attacks and will not stop a chest pain attack that has already started.

To get the most benefit, you must take Isonitrate 30mg Tablet SR regularly every day at the same times as directed by your healthcare provider. You can take this tablet with or without food, but keeping a consistent routine is key to maintaining steady medicine levels in your body. Combining this medication with heart-healthy lifestyle choices, such as eating a low-salt diet and doing gentle, doctor-approved exercise, can improve your long-term results.

Headaches are a very common side effect when you first start taking this medicine, but they usually get better as your body adjusts to the treatment. However, if you experience severe dizziness, an unusually fast or slow heartbeat, or fainting, you should consult your doctor right away. Always discuss any persistent or bothersome symptoms with your healthcare team.

Before starting Isonitrate 30mg Tablet SR, talk to your doctor if you have a history of low blood pressure, severe anaemia, or recently had a heart attack. Do not take this if you are using medications for erectile dysfunction or high blood pressure in the lungs, as this combination can cause a sudden and dangerous drop in blood pressure.

Drinking alcohol while taking Isonitrate 30mg Tablet SR can make you feel extremely dizzy and cause your blood pressure to drop too low. If you are pregnant, planning to breastfeed, or are an older adult, you should consult your doctor to discuss whether this medicine is safe for your specific situation.

How Isonitrate 30mg Tablet SR Works

Isonitrate 30mg Tablet SR contains isosorbide mononitrate, which belongs to a group of medicines called vasodilators, which relax and widen blood vessels. Inside your body, the medicine releases a natural substance called nitric oxide, which signals the muscles in your blood vessel walls to relax. When these blood vessels widen, blood flows much more smoothly, delivering vital oxygen to your heart muscle. This widening also makes it easier for your heart to pump blood to the rest of your body, which directly prevents the strain and oxygen shortage that trigger painful chest pressure.
