Corgard (nadolol) is a beta blocker most commonly used to treat hypertension (high blood pressure) and angina (chest pain). It is relatively unique among beta blockers in that Corgard is typically taken only once per day, compared to two or three daily doses usually taken with other medications in the beta blocker class.

Like all beta blockers, Corgard works by slowing the rate at which the heart beats and relaxing blood vessels, which lowers blood pressure and reduces strain on the heart.

Dosage & Administration

Corgard comes in tablets, usually taken once per day. They may be taken with or without food according to personal preference, and can be crushed and mixed with food for patients who have difficulty swallowing tablets.

There are many individual variables that will influence dosage with Corgard; the severity of the condition, other medical conditions present, other medications being taken, age, weight, and other factors should be taken into consideration. In otherwise healthy adults, treatment is typically:

  • Start with 40 mg per day for at least 3 days, after which effects should be evaluated.
  • If 40 mg is not producing adequate results, increase dosage to 80 mg per day for at least 3 days.
  • Dosage can be further increased in 40 mg increments every 3 days up to 320 mg per day.
  • The vast majority of patients find 40 to 80 mg per day to be sufficient in both hypertension and angina.

It takes a few days to a week for full effects of the medication to be felt. During the start of treatment and after any dosage adjustments it's important to attend doctor checkups to evaluate the medication's effectiveness and monitor for developing side effects.

Other medications are commonly taken along with Corgard, such as diuretics to further reduce blood pressure or nitroglycerin to quickly alleviate angina episodes. Keep in mind that any medications that produce the same effects as Corgard---influencing heart rate, circulation, or blood pressure---have the potential to cause complications. Check with a doctor or pharmacist if unsure of the safety of mixing medications.

Treatment with Corgard is typically long term, often spanning years. It helps manage symptoms but is not a cure for the underlying issues; in the majority of cases lifestyle changes, such as improving diet and exercising, are necessary to resolve the root cause of the condition. Patients who do successfully make long-term lifestyle changes are often able to eventually stop taking medications.

Warnings & Side Effects

Patients taking this or any other beta blocker medication should be aware that treatment should not stop suddenly; dosage should be gradually tapered off over the course of several weeks. Abruptly stopping treatment can produce very serious complications. Speak with a doctor about a discontinuation plan if stopping treatment or switching to a different medication.

Side effects from Corgard are usually mild and related to lowered blood pressure, including:

  • Mild fatigue
  • Mild confusion
  • Sweating
  • Lightheadedness
  • Weakness
  • Cold and/or tingling hands and/or feet

The above side effects are generally not cause for concern unless severe. In the majority of cases the above side effects, if experienced at all, will fade away as the body adapts to its new lower blood pressure.

Rarely more serious side effects develop, which warrant medical attention:

  • Severe fatigue
  • Severe confusion
  • Difficulty breathing
  • Fainting
  • Blurred vision
  • Chest pain or persistent discomfort
  • Irregular heartbeat

Men taking beta blockers like Corgard sometimes experience erectile dysfunction. This condition may be treatable with other medications, but keep in mind that many short-term treatments can significantly raise blood pressure. Speak with a doctor about suitable options.

Beta blockers can harm unborn or nursing babies if taken while pregnant or breastfeeding.
