Product introduction

Nitro 6.4mg Tablet SR is used to treat and prevent heart-related chest pain (angina). Angina occurs when the heart muscle is not getting enough blood. This medicine works by relaxing and widening blood vessels so blood can flow more easily to the heart.

Nitro 6.4mg Tablet SR is used to treat chest pain and also to promote healing of skin tear in the back passage

Benefits of Nitro Tablet SR

In Treatment of Angina (heart-related chest pain)

Nitro 6.4mg Tablet SR helps in prevention as well as treatment of angina. Angina is a chest pain that is usually caused by narrowing of the blood vessels which supply your heart. This means your heart does not get enough oxygen. Nitro 6.4mg Tablet SR works quickly to relax the muscles and blood vessels in your heart so more blood (and oxygen) gets to your heart. This reduces the pain and discomfort that angina causes.
You should take this medicine at the first sign of chest pain. If the first tablet does not work, you can take a second tablet after 5 minutes. However, if your chest pain does not go away after 15 minutes, you should get urgent medical attention. This could be a sign of a heart attack. Nitro 6.4mg Tablet SR also helps prevent chest pain if taken before exercising or doing other strenuous activities.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

FAQs

Can I take sildenafil if I am taking Nitro 6.4mg Tablet SR?

No, you should not take sildenafil if you are taking Nitro 6.4mg Tablet SR. Taking these two medicines together can cause an excessive fall in blood pressure, which may even be life-threatening.

What effect does Nitro 6.4mg Tablet SR have on blood pressure?

Nitro 6.4mg Tablet SR decreases the blood pressure by relaxing the blood vessels, but is not recommended for the treatment of high blood pressure. The drop in blood pressure may cause lightheadedness, especially when changing your position suddenly.

Does the effect of Nitro 6.4mg Tablet SR wear off after some time?

Yes, excessive use of Nitro 6.4mg Tablet SR may cause tolerance which means that Nitro 6.4mg Tablet SR may lose its effectiveness on you. Therefore, usually the doctors prescribe the smallest dose required for effective relief of acute angina attack. This helps maintain the effectiveness of Nitro 6.4mg Tablet SR.

What does too much Nitro 6.4mg Tablet SR do?

Excess Nitro 6.4mg Tablet SR may result in low blood pressure, sweating, nausea, vomiting, headache, weak and fast pulse. It may also cause weakness, lightheadedness on standing and the patient might even faint. The patient will require emergency medical treatment in such a case.

Can I stop using Nitro 6.4mg Tablet SR as I feel better now?

Stopping Nitro 6.4mg Tablet SR suddenly may bring on attacks of angina, especially if you have been using it for several weeks or more. Talk to your doctor who will advise you to reduce the dose gradually over 4 to 6 weeks before you stop using it completely.

Does Nitro 6.4mg Tablet SR stop heart attacks?

Nitro 6.4mg Tablet SR is prescribed to prevent attacks of heart-related chest pain (angina) in patients with coronary artery disease. In this disease the blood vessels (coronary arteries) which supply blood to the heart become narrowed because of which the heart has to work harder to get enough oxygen. Nitro 6.4mg Tablet SR prevents angina by relaxing the blood vessels so that the heart does not have to work very hard. Also, relaxation of coronary arteries increases the oxygen supply to the heart.
