Nitroglycerin 6.4mg

Nitroglycerin 6.4mg Uses

Nitroglycerin 6.4mg is prescribed to:

• Relieve acute chest pain (angina) by improving blood flow to the heart.
• Prevent angina attacks in people with coronary artery disease.
• Provide rapid relief of chest discomfort associated with heart conditions, particularly during episodes of stress, physical activity, or after meals.

How Does Nitroglycerin 6.4mg Work

Nitroglycerin works by increasing the levels of nitric oxide in the blood vessels, which causes the smooth muscle of the blood vessels to relax and dilate (widen). This relaxation allows for improved blood flow to the heart muscle, reducing its workload and relieving the chest pain caused by angina. Nitroglycerin reduces the amount of oxygen the heart muscle needs, providing effective relief from angina symptoms.

How to Use Nitroglycerin 6.4mg

• Dosage: Take one Nitroglycerin 6.4mg tablet under your tongue at the onset of chest pain or as prescribed by your healthcare provider.
• Administration: Place the tablet under your tongue and allow it to dissolve completely. Do not chew or swallow the tablet.
• Frequency: If the chest pain persists after the first dose, you can take an additional tablet every 5 minutes, up to a maximum of 3 tablets within 15 minutes. If pain continues or worsens, seek emergency medical attention.
• Effect Duration: Nitroglycerin typically starts working within 1-5 minutes, with relief lasting for about 30 minutes to 1 hour.

Important Notes

• Always follow your doctor’s instructions regarding the dosage and frequency of use.
• If you frequently experience angina, consult your healthcare provider to adjust your treatment plan accordingly.
• Nitroglycerin is for acute relief and is not a substitute for long-term heart medications.

Drug Interactions

Nitroglycerin 6.4mg may interact with:

• Nitrates (such as nitroglycerin) or other medications used for erectile dysfunction (e.g., Sildenafil, Tadalafil), which can cause a dangerous drop in blood pressure when combined with Nitroglycerin.
• Certain blood pressure medications or diuretics, which may enhance the effects of Nitroglycerin and cause excessive lowering of blood pressure.
• Alcohol, which can increase the blood pressure-lowering effects of Nitroglycerin.

Inform your doctor about all medications, supplements, and herbal products you are using to avoid potential interactions.

Food Interactions

• Avoid excessive alcohol consumption while taking Nitroglycerin, as it can lead to an increased risk of dizziness or fainting.
