Product Overview
Carvedilol Tablets have Carvedilol as their active ingredient. This medication is a nonselective beta-blocker and alpha-1 blocker that helps treat high blood pressure, heart failure, and angina. It works by easing the heart’s workload and improving blood flow. Carvedilol does this by blocking certain receptors, which lowers heart rate, blood pressure, and stress on the heart.
You take these tablets orally with food to help your body absorb the medicine better and reduce side effects. They come in strengths of 3.125 mg, 6.25 mg, 12.5 mg, & 25 mg. This medication is generally for adults but can be adjusted for children based on their weight.
Some common side effects of Carvedilol include tiredness, dizziness, and headaches. Don’t stop taking Carvedilol suddenly to avoid serious problems. You can also buy Carvedilol online from Canada at affordable prices.

How to Take Carvedilol?
- Before using Carvedilol, whether in tablet or capsule form, read the patient information leaflet thoroughly to ensure safe and effective use.
- If you have any questions or concerns about the medication, consult your doctor or pharmacist.
- Take Carvedilol orally with food, as directed by your healthcare provider.
- Swallow the tablet whole with a drink of water. Additionally, do not open, crush, or chew the capsules.
- To reduce the risk of various side effects, start with a low dosage as advised by your doctor and gradually increase if necessary.
- Maintain consistency in dosage and timing to achieve the best results—take the medication at the same time each day.
- It may take one to two weeks to notice improvements in hypertension symptoms. Continue taking the medication even if you feel well.
Missed Dose
For optimal effectiveness when taking Carvedilol, it’s important to use the medication consistently at the same time each day. If you forget to take a dose, administer it as soon as you realize the oversight. If it’s nearly time for your next scheduled dose for Carvedilol, skip the one you missed and continue with your regular dosing routine without trying to compensate by doubling up on the medication. To help remember your doses, consider setting an alarm or reminder on your phone.
[Note: Do not take two doses of Carvedilol at the same time to compensate for a missed dose. This can increase your chances of experiencing serious side effects.]
Overdose
It’s important not to take Carvedilol in higher doses or for a longer period than prescribed. Exceeding the recommended dosage of Carvedilol can lead to severe side effects, including lowered blood pressure, difficulty breathing, and a reduced heart rate. If you suspect an overdose and observe symptoms such as trouble breathing, seizures, fainting, or unresponsiveness, immediate medical intervention is crucial.
[Note: If you notice you have taken too much medication, call your local emergency number immediately.]
How Does Carvedilol Work?
It works as both an alpha-1 blocker and a nonselective beta-blocker, affecting various receptors in the body. By blocking these receptors, Carvedilol helps lower blood pressure and heart rate, reduce the heart’s workload, and improve heart function. It does this by decreasing the strength of heart contractions and dilating blood vessels.

Frequently Asked Questions
What is Carvedilol used for?
Carvedilol is prescribed either alone or in combination with other medicines to manage high blood pressure (hypertension). Sustained high blood pressure can strain the heart and arteries, potentially impairing their function over time.
Is Carvedilol a beta-2 blocker?
Carvedilol predominantly blocks human cardiac beta-2 adrenoceptors more than beta-1 adrenoceptors. This action is thought to contribute to its beneficial effects in treating heart failure, with a persistent blockade of beta-adrenoceptors due to Carvedilol accumulating in cardiac tissue.
Who should not take Carvedilol?
Individuals should avoid taking Carvedilol if they have an allergy to it or if they suffer from conditions such as bronchitis, asthma, emphysema, serious liver disease, or severe heart conditions like heart block, “sick sinus syndrome,” or slow heart rate unless a pacemaker is present.
Is Carvedilol beneficial for the kidneys?
Carvedilol shows antihypertensive and renal vasodilating properties, which means it can help lower blood pressure and decrease renal vascular resistance without changing the renal blood flow, glomerular filtration rate, or filtration fraction. These effects are observed both acutely and after long-term treatment.
