What is Coreg?

Coreg is a brand name for a medication called carvedilol. It belongs to a class of drugs known as beta-blockers. Carvedilol works by blocking the effects of certain natural substances in the body, such as adrenaline, on the heart and blood vessels. This helps to lower blood pressure, improve heart function, and reduce the workload on the heart.

Coreg is commonly prescribed for the treatment of:

  • Hypertension (high blood pressure)
  • Heart failure
  • Left ventricular dysfunction following a heart attack
  • It may also be used in combination with other medications to manage certain heart conditions.

Coreg is typically taken orally, with or without food, as directed by a healthcare professional. The dosage prescribed will depend on the individual's medical condition and response to treatment.

Side Effects of Coreg

While Coreg is generally well-tolerated, like any medication, it may cause side effects in some people. Common side effects may include:

  • Dizziness or lightheadedness
  • Fatigue
  • Diarrhea
  • Slow heartbeat
  • Changes in blood sugar levels
  • Cold hands or feet
  • Difficulty breathing
  • Weight gain

Serious side effects are rare but can occur. These may include severe dizziness, fainting, difficulty breathing, swelling of the ankles/feet, or sudden weight gain.


Before taking Coreg, it's important to inform your doctor about any existing medical conditions, allergies, or medications you're currently taking. Additionally:

  • Do not stop taking Coreg suddenly without consulting your doctor, as this can lead to worsening symptoms.
  • Avoid activities that require alertness (such as driving) until you know how Coreg affects you.
  • Limit alcohol consumption, as it can further lower blood pressure and increase the risk of side effects.
  • Check your blood pressure and heart rate regularly while taking Coreg.


Can Coreg be taken with other medications?

Coreg may interact with certain medications, including other blood pressure-lowering drugs, diabetes medications, and certain antidepressants. Always inform your doctor about all medications you are taking.

Can Coreg be taken during pregnancy or while breastfeeding?

It is important to discuss the risks and benefits of taking Coreg during pregnancy or while breastfeeding with your doctor.

How long does it take for Coreg to start working?

Coreg may start to lower blood pressure within hours of taking the first dose, but it may take several weeks to experience the full benefits of the medication.

Can Coreg cause weight gain?

Yes, weight gain is a potential side effect of Coreg. If you notice significant weight gain while taking Coreg, inform your doctor.

Is it safe to drink grapefruit juice while taking Coreg?

Grapefruit juice may interact with Coreg and increase the risk of side effects. It's best to avoid grapefruit juice while taking Coreg.

I've been a Canadian Med Center customer for about 6 years now. In all that time there was never once that I considered taking my business elsewhere. They do a great job and the people they contract with are also super.

Always appreciate their prompt service but especially appreciate their hanging in there when there was difficulty getting my doctor to renew my prescription!
