Common Use

Imdur is a nitrate medication. Its active ingredient, Isosorbide Mononitrate, works by dilating blood vessels, making it easier for the heart to pump blood. It is primarily used to treat angina attacks (chest pain). Other similar nitrate medications include Isosorbide Dinitrate (Dilatrate-SR, Isochron, Isordil Titradose) and Nitroglycerin (NitroQuick, Nitrolingual, Nitrostat, Nitro-Dur).

Dosage and Direction

The recommended dosage of Imdur is 20 mg of immediate-release tablets taken twice daily, with at least seven hours between doses to prevent tolerance. For extended-release tablets, the dosage ranges from 30-240 mg taken once daily.

Precautions

• Do not take Imdur if you use Sildenafil (Viagra) due to potential serious side effects.
• Avoid Imdur if you are allergic to Isosorbide Dinitrate, Isosorbide Mononitrate, or Nitroglycerin.
• Do not use Imdur if you experience early heart attack symptoms like chest pain, nausea, sweating, shoulder pain, or general discomfort.
• Inform your doctor if you have conditions like congestive heart failure, low blood pressure, or kidney disease before starting Imdur.
• Initial treatment may cause severe headaches. Imdur is for preventing angina attacks, not treating ongoing ones.
• Do not stop Imdur suddenly, as it may trigger severe angina attacks.
• Rise slowly from sitting or lying positions to avoid a sudden drop in blood pressure.

Contraindications

Imdur is contraindicated for patients with hypersensitivity or unpredictable reactions to nitrates or nitrites.

Side Effects

Common side effects of Imdur include headaches, dizziness, palpitations, a severe drop in blood pressure when standing, and weakness.

Drug Interactions

• Avoid using Imdur with Sildenafil (Viagra), Vardenafil (Levitra), or Tadalafil (Cialis) as it may dangerously lower blood pressure.
• Do not combine Imdur with calcium channel blockers like Diltiazem (Dilacor, Tiazac, Cardizem) or Verapamil (Isoptin, Calan, Verelan).

Missed Dose

If you miss a dose, take it as soon as you remember. If it's almost time for the next dose, skip the missed dose. Never take a double dose. Resume your regular dosing schedule the next day.

Overdose

Symptoms of overdose may include rapid heartbeat, nausea, vomiting, fever, confusion, dizziness, severe headache, vision problems, stomach pain, bloody diarrhea, sweating, trouble breathing, cold or clammy skin, fainting, light-headedness, or seizures.

Storage

Store Imdur at room temperature, between 20-25°C (68-77°F). Keep it away from moisture, heat, and sunlight. Do not store in the bathroom or places accessible to children.
