MEPHACOR: Uses, Facts, Dosage, Side effects, FAQs

The active substance in MEPHACOR is (bisoprolol fumarate). Bisoprolol fumarate belongs to a group of medicines called beta-blockers. These medicines work by affecting the body’s response to some nerve impulses, especially in the heart. As a result, bisoprolol slows down the heart rate and makes the heart more efficient at pumping blood around the body. MEPHACOR is used:

  • To treat stable chronic heart failure(heart failure occurs when the heart muscle is weak and unable to pump enough blood to supply the body’s needs). Bisoprolol(MEPHACOR) is used in combination with other medicines suitable for this condition (such as ACE-inhibitors, diuretics, and heart glycosides).
  • In treatment of coronary heart disease and chest pain (angina pectoris) caused by shortage of oxygen in the heart muscle.
  • In treatment of high blood pressure (hypertension). 

Dosage and Administration

  • Always take MEPHACOR Tablets exactly as your doctor has told you. You should check with your doctor or your pharmacist if you are not sure.
  • MEPHACOR Tablets should be taken in the morning, before, with or after breakfast. 
  • Swallow the tablet whole with some water and do not chew or crush them. 
  • This treatment should be initiated by a specialist in cardiology or internal medicine. 
  • Children under 12 years and adolescents: MEPHACOR Tablets are not recommended for use in children.
  • If you are about to be started on any new medicine tell your doctor and pharmacist that you are taking MEPHACOR Tablets. 
  • If you forget to take MEPHACOR Tablets: If you forget to take a dose, take it as soon as you remember it unless it is nearly time for your next dose. Do not take a double dose to make up for a forgotten dose. 
  • Do not stop treatment suddenly or change the recommended dose without talking to your doctor first. If you need to stop treatment, it must be done gradually, to avoid side effects.
  • Avoid drinking excessive alcohol, since it may increase the blood pressure-lowering effect of bisoprolol. Avoid drinking alcohol altogether, if it makes you more dizzy or more light-headed than usual. 

How does MEPHACOR work?

MEPHACOR belongs to a group of drugs called (beta-blockers), that block beta-receptors in the heart, lungs, and other body systems. Blocking these receptors prevents the action of two chemicals called noradrenaline and adrenaline, which are found naturally in the body.

Bisoprolol(MEPHACOR) works by slowing the heart rate and lowering blood pressure, which helps the heart to pump the blood more efficiently and reduces the workload on the heart.

MEPHACOR also used to prevent migraines. In addition, bisoprolol can also be used to control symptoms associated with anxiety or an overactive thyroid gland (thyrotoxicosis), such as a rapid pulse, sweating and tremors.

When should you take MEPHACOR?

MEPHACOR tablets can be taken anytime in the morning or evening, usually prescribed once daily. However, your very first dose of MEPHACOR Tablets may make you feel dizzy, so it is better to take your first dose at bedtime. After that, if you do not feel dizzy, you may take it any time of the day.

When does the MEPHACOR tablets effect begin?

MEPHACOR may take up to a week before the full effects on blood pressure and heart rate are seen, although some effect is evident within 24 hours. Effects of bisoprolol( MEPHACOR) persist for 24 hours following a single dose. 

What is the best time of day to take MEPHACOR?

Bisoprolol( MEPHACOR) slows down your heart rate and makes it easier for your heart to pump blood around your body. Your very first dose of MEPHACOR may make you feel dizzy, so take it at bedtime. After that, if you don’t feel dizzy, it’s best to take it in the morning. It’s usual to take MEPHACOR once a day in the morning.

Will the treatment with MEPHACOR last for life?

In people who have had a heart attack, beta blockers( e.g. MEPHACOR) help reduce the risk of further ones. Guidelines recommend that all patients who have had a heart attack should be prescribed a beta blocker before hospital discharge as part of a package of risk reduction measures. Treatment should usually continue for life.

While the drugs are part of the standard treatment after a heart attack, it now appears that they can be discontinued three or four years after a heart attack.
