Metoprolol lowers blood pressure by blocking a receptor in blood vessels called the beta-1 receptor. By blocking this receptor, chemicals like norepinephrine, epinephrine, and isoproterenol, which cause blood vessel contraction and increase blood pressure, are unable to bind to it. Additionally, by blocking beta-1 receptors in the heart, metoprolol reduces heart rate and the force of heart contractions, further helping to lower blood pressure. 

Allergies/Hypersensitivity

If you are allergic to this medicine, then inform your doctor immediately. 

Pregnancy

Metoprolol crosses the placenta and can cause fetal abnormalities if taken during pregnancy, so if you are pregnant or planning to conceive, inform your doctor about it.

Breastfeeding

Metoprolol passes into breast milk in small amounts and is generally considered safe during breastfeeding, with no major harmful effects reported in infants.

Daily Dose

Missed Dose

If you forget to take your medicine, take the medication as soon as you remember. If it’s nearly time for your next dose, skip the missed one and continue with your regular schedule. Always consult the doctor before making any changes to your dosage.

Overdose

Metoprolol is a cardioselective beta blocker. The FDA approved it for the treatment of high blood pressure, chest pain, and heart failure and for reducing death risk after heart attack. Off-label uses of this medicine include migraine prevention, fast heart rhythms, and anxiety. It works by blocking beta receptors in the heart, which slows heart rate and reduces strain. The common side effects of this medicine are tiredness, dizziness, slow heartbeat, depression, and stomach upset. It interacts with alcohol and foods and can lower blood pressure.  People with very slow heart rates, severe heart blocks, shock, or uncontrolled heart failure should avoid it.  Taking more than 1000 mg can cause dangerously slow heart rate, very low blood pressure, fainting, seizures, breathing problems, and cardiac arrest.

When to take Metoprolol tablets?

Metoprolol usually causes dizziness, which is why doctors advise patients to take it before bedtime.

Can metoprolol cause bradycardia?

A study conducted to examine the effect of metoprolol on heart rate in both males and females found that women who consumed a high dose of metoprolol had a lower heart rate, but the same effect was not observed in men.

Will Metoprolol lower heart rate?

Yes, Metoprolol lowers heart rate by blocking adrenaline’s effects on the heart.  It’s important to follow your doctor’s instructions and not stop it suddenly.
