Nicorandil
About Nicorandil
Nicorandil is a prescription medication used to prevent and manage chest pain, also known as angina. It belongs to a group of medicines that help widen blood vessels, making it easier for blood and oxygen to reach your heart. This medicine is typically prescribed for long-term protection rather than relieving sudden, sharp chest pain.
For the best results, you should take Nicorandil consistently at the same times every day as directed by your doctor. You can take this tablet with or without food, swallowing it whole with a glass of water. Combining this medication with heart-healthy lifestyle habits, such as eating a low-salt diet and staying gently active, can significantly improve your treatment outcomes.
While taking Nicorandil, some people may experience mild side effects like headaches, especially when first starting the treatment. However, you must contact your doctor immediately if you experience severe dizziness, fainting, or painful ulcers in your mouth, stomach, or skin.
Before starting Nicorandil, tell your doctor if you have low blood pressure, heart failure, or potassium imbalances. Do not take this if you have recently had a heart attack, are in cardiogenic shock, or have been diagnosed with severe low blood volume.
This medication can interact dangerously with alcohol, causing your blood pressure to drop too low, and smoking can decrease its overall effectiveness. Pregnant women, breastfeeding mothers, and elderly patients should consult their healthcare provider before using Nicorandil to ensure it is completely safe for them.

FAQs
Nicorandil is used to prevent or treat angina pectoris (heart-related chest pain) in adults who cannot take beta-blockers (blood pressure-lowering pills).
Nicorandil contains Nicorandil that works by relaxing and widening blood vessels. Thereby, Nicorandil reduces the workload of the heart by making it easier for heart to pump blood around the body and does not require much oxygen. Also, Nicorandil helps to prevent angina by increasing oxygen and blood supply to the heart muscle by widening coronary arteries within the heart.
Nicorandil may cause headache as a common side effect especially in the first few days of treatment. However, if the condition persist or worsens, please consult a doctor so that the dose may be reduced initially.
Nicorandil is not recommended for patients with severe hypotension (low blood pressure) as it may increase the risk of worsening the condition. Therefore, inform your doctor if you have low blood pressure before taking Nicorandil.
You are not recommended to take aspirin (pain reliever) with Nicorandil as co-administration of these two medicines may increase the risk of ulcers or other adverse effects. However, please consult a doctor before taking other medicines with Nicorandil.
You are recommended to avoid taking Nicorandil if you have hypotension (severe low blood pressure), low blood volume, pulmonary oedema (accumulation of fluid in the lungs) or any heart problems such as left ventricular failure with low filling pressure, cardiac decompensation or cardiogenic shock.
You are not recommended to take more than the prescribed dose of Nicorandil as it may cause Nicorandil overdose resulting in symptoms such as weakness, dizziness (signs of low blood pressure), fast or irregular heartbeat. However, if you experience any of these symptoms while taking Nicorandil, please consult a doctor immediately.
No, Nicorandil is a long-term preventative medicine and will not stop an active, sudden angina attack. You must use your fast-acting rescue medication, such as a nitroglycerin spray or tablet, for immediate relief. Talk to your doctor if your chest pain is frequent or worsening.
No, you should swallow the tablet whole with a glass of water. Crushing or chewing the tablet can alter how the medicine is absorbed into your bloodstream and may reduce its effectiveness. If you have trouble swallowing tablets, talk to your doctor or pharmacist.
No, you should avoid alcohol while taking this medicine. Alcohol increases the blood vessel-widening effects of the drug, which can cause your blood pressure to drop dangerously low, resulting in severe dizziness or fainting. Talk to your doctor if you have concerns.
If you notice painful ulcers or sores developing in your mouth, on your skin, or in your genital area, contact your doctor immediately. This is a recognised serious side effect that requires medical evaluation, and your doctor may need to stop your treatment.
No, you must never take sildenafil, tadalafil, or other erectile dysfunction drugs while taking Nicorandil. Combining these medications can cause a sudden, severe, and potentially life-threatening drop in blood pressure. Talk to your doctor to discuss safe alternative options.
There is limited safety data regarding the use of this medicine during pregnancy or breastfeeding. It is generally not recommended unless deemed absolutely necessary by your healthcare provider. Talk to your doctor or pharmacist to weigh the potential risks and benefits.
