MYONIT INJECTION

Myonit Injection is used to treat and prevent heart-related chest pain (angina) and hypertension (high blood pressure) during surgery. This medicine works by relaxing and widening blood vessels so blood can flow more easily to the heart. It has a very short-lived effect. Myonit Injection is given as an injection under the supervision of a doctor with careful blood pressure monitoring. This is given as a continuous infusion into a vein and should not be stopped abruptly. It should not be mixed with any other medication of any kind.The most common side effect of Myonit Injection is a headache which may be severe. This can sometimes be helped by drinking plenty of fluids and avoiding alcohol. You may also experience lightheadedness, which could increase your risk of having a fall. There are other, rarer side effects, some of them serious. Ask your doctor and read the leaflet which comes with the medicine to make sure you are keeping safe.Do not use Myonit Injection if you are taking medicines to treat high blood pressure in your lungs (pulmonary hypertension), or erectile dysfunction; or if you have anemia or glaucoma (increased pressure inside the eye). Always tell your doctor what other health conditions you have and what other medicines you are taking. It is best not to drink alcohol with this medicine as it increases some of the side effects. If you are affected by dizziness, avoid driving. If you are pregnant, thinking about becoming pregnant, or breastfeeding, ask your doctor before taking this medicine.

scienceMechanism of Action (How it works)

expand_more

Myonit Injection is a nitrate. It works by improving blood supply to heart and relaxing the blood vessels which decreases the oxygen demand of the heart and reduces its workload, thereby preventing/treating attacks of angina (chest pain). Relaxation of blood vessels lowers blood pressure.

helpFrequently Asked Questions

Does the effect of Myonit Injection wear off after sometime?

expand_more

Yes, excessive use of Myonit Injection may cause tolerance which means that Myonit Injection may lose its effectiveness on you. Therefore, doctors usually prescribe the smallest dose required for effective relief of acute angina attacks. Also, it is usually prescribed in morning and afternoon doses to give nitrate-free interval. Take it strictly as per the dosing interval prescribed by your doctor to prevent tolerance and maintain the effectiveness of Myonit Injection.

What does too much Myonit Injection do?

expand_more

Excess Myonit Injection 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.

Does Myonit Injection stop heart attacks?

expand_more

Myonit Injection 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 narrow because of which the heart has to work harder to get enough oxygen. Myonit Injection 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.
