What is Toprol XL?

Toprol XL is prescribed to be used alone or together with other medications to treat high blood pressure (hypertension). Blood pressure is a measurement of the amount of force in a person's blood vessels when their heart is beating and at rest. If someone has high blood pressure, it means that their heart is working harder than it should to pump blood around the body. If this continues for a long time, the heart and arteries may not function properly. This could result in damaged blood vessels of the brain, heart, and kidneys which could result in a stroke, heart failure, or kidney failure. Toprol XL is also used to treat severe chest pain (angina), and heart failure, and lowers the risk of repeated heart attacks.

You can buy Toprol XL at My Drug Center and we also have the Toprol XL generic, called Metoprolol XL. The Metoprolol Succinate generic may not be available in all strengths or forms as the brand-name drug.


How does Toprol XL work?

Toprol XL comes as a tablet for oral administration and contains the active ingredient Metoprolol Succinate. The Metoprolol Succinate dosage in this drug is a beta-blocker, which works by preventing norepinephrine (adrenalin) from acting on beta receptors in the blood vessels and in the heart. This relaxes the blood vessels, which help lower the heart rate and decrease the heart’s demand for oxygen. Blood pressure is then lowered, and chest pain is reduced.

Before taking your prescribed medication read all the instructions that was provided by your pharmacist. Take Toprol XL orally once a day with a full glass of water. This medication may be administered with or without a meal. Make sure you take your prescribed Metoprolol Succinate dosage at the same time each day to create a routine for yourself and to ensure an even spread of medication in your system. For optimal results take this medication on a regular basis. Do not change or increase your dose. You should continue taking this medication even if you feel well. 

Toprol XL or the Metoprolol Succinate generic may be administered with or without a meal.  If you take Toprol XL with another medicine, make sure to follow your doctor's dosing instructions very carefully.


Toprol XL (Metoprolol Succinate) may contain medical and non medical ingredients that could cause an allergic reaction. Your doctor needs to know about any allergies you have, as well as any known medical conditions relating to heart disease. Also, you should tell your doctor about any medications or supplementation you take, whether prescription, over-the-counter, vitamins, recreational drugs, and dietary or herbal supplements to avoid interactions with Toprol XL.

If you are taking other medication, speak with your doctor to ensure you are scheduling them properly to allow full absorption for the medications.

A lifestyle change to include diet and exercise will also improve the effect of Metoprolol Succinate for reducing managing blood pressure. Healthy eating and change of negative habits like excessive drinking or smoking will do much to help improve the effect of the medication.
