How does this medicine work?

These medicines are used to treat many conditions such as hypertension (high blood pressure) and heart conditions. They are also used to treat migraine headaches, fainting spells, and occasionally behavior and emotional problems or other conditions specified by your healthcare provider.

Beta blockers work by blocking the response to some nerve impulses in certain parts of the body. As a result, they help lower the heart rate and blood pressure, and decrease the heart's workload. They also help the heart beat more regularly.

How should I give it?

Most of these medicines come in pill form. Some are available in liquid form and in injection form.

Give it at regular times to keep a steady level in the bloodstream. Use this medicine exactly as prescribed, even if your child feels fine.

___ If using the liquid form, shake well right before using. Draw up the correct amount in the medicine dropper or oral syringe. Give a small squirt of the medicine inside the cheek. To avoid choking, let your child swallow each squirt before giving more.

___ For babies, you may want to mix the medicine with a small amount of formula or breast milk and give it with a bottle nipple before feeding. Do not add the medicine to a whole bottle because if your baby does not finish it, you will not know how much of the medicine was taken.

If your child is taking more than one dose daily, the last dose may be given at bedtime to avoid tiredness during the day.

Note: if your child's medicine is a long-acting product (noted by XL or SR after the name), it should not be crushed, chewed, or cut.

What should I do if a dose is missed?

Check with your doctor before stopping this medicine. The dose is usually lowered over 1 or 2 weeks.
