Calcium channel blockers are used to treat many conditions, including high blood pressure (hypertension) and some heart conditions. They affect the movement of calcium into the cells of the heart and blood vessels. As a result, they relax blood vessels and reduce the heart's workload. They also slow the heart rate.
Most of these medicines come in pill form. Some are available in liquid form and injection form.
Give it at regular times to keep a steady level in the bloodstream. If your child is taking more than one dose daily, the last dose may be given at bedtime to avoid tiredness during the day.
Give this medicine exactly as prescribed, even if your child feels fine.
Your child should be awake and alert when taking any medicine. Follow these instructions:
___ 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.
