Has your doctor prescribed you a medicine called Metoprolol? Maybe it's for your high blood pressure, or maybe it's for a heart condition. It's normal to be a little nervous and curious about a new medication. So, today we'll talk about exactly what Metoprolol is, what it does to the body, and what we need to be careful about when using this medicine.
What kind of medicine is Metoprolol?
Simply put, Metoprolol is a drug that belongs to a class of drugs called 'beta blockers' . Its main function is to control your heart rate and blood pressure, helping your heart pump blood throughout the body without having to work as hard.
This medicine is mainly used for the following conditions:
- High Blood Pressure: Control your blood pressure.
- Heart Failure: Support the heart when it is in a weakened state.
- Angina: Prevent chest pain caused by blockage of the arteries that supply blood to the heart.
Things you need to tell your doctor before taking this medicine
Before you start using Metoprolol, it is extremely important to tell your doctor about any other medical conditions you have, allergies, and other medications you are taking, as this medication may not be compatible with some medical conditions.
| Be sure to tell us if you have these conditions. | Why is it important? |
|---|---|
| Diabetes | This medicine may affect blood sugar levels and may mask some of the symptoms of low blood sugar (hypoglycemia). |
| Heart or blood vessel disease (e.g., very slow heartbeat, heart block, Raynaud's disease) | Metoprolol can further slow the heart rate, which can worsen existing heart conditions. |
| Kidney or liver disease | Because diseases of these organs affect the process of removing drugs from the body, the dosage of the drug may need to be changed. |
| Lung or respiratory disease (e.g., asthma, emphysema) | This medication can cause airway constriction and increase breathing difficulty. |
| Pheochromocytoma (a tumor of the adrenal gland) or thyroid disease | Metoprolol may modify or mask the symptoms of these conditions. |
| If you are pregnant, trying to get pregnant, or breastfeeding | Since this medication can affect the child, you should talk to your doctor and make the best decision. |
| Allergies to other medications, foods, or substances | It is very important to inform your doctor if you are allergic to metoprolol or any other beta blocker. |
How to use Metoprolol correctly?
- This medicine is for oral use. Take it exactly as prescribed by your doctor.
- Try to take your medicine at the same time every day . If possible, take it with a meal. This will help the medicine absorb better.
- Some tablets are scored in the middle so that you can break them. If the tablet is too big, you can break it in half and drink both pieces at once . Remember, don't drink just one piece.
- The most important thing is to continue taking this medicine until your doctor tells you to stop. If you stop taking it suddenly, your condition may worsen.
- If you think you have taken too much of this medicine, immediately call the National Poisons Information Centre at the Colombo National Hospital, or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose (e.g., it is only a few hours away), skip the missed dose and take your next dose at the scheduled time. Never take a double dose.
