GTN

GTN Spray starts working very quickly. If the medicine is kept under the tongue, the effect starts 1-3 minutes later and reaches its maximum within 5 minutes.

GTN Spray 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.

Yes, excessive use of GTN Spray may cause tolerance which means that GTN Spray 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 GTN Spray.

Excess GTN Spray 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.

Stopping GTN Spray 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.

GTN Spray 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. GTN Spray 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.

No, you should not take GTN Spray if you have taken sildenafil. Taking these two medicines together may increase the risk of excessive fall in blood pressure, which is hazardous. Maintain a gap of at least 24 hours if you have to use GTN Spray after taking sildenafil.
