Beta-adrenergic Blocking Agents *** Before Using *** How to Use *** Fore Safe Use *** Side Effects *** Additional Information
Before Using
In deciding to using a medication,
the chance of taking the drug must be weighed against the good it will
do. This is a decision you will make. For the beta-blockers,
the following must be considered
Allergic reaction
Tell your family doctor if you have any unusual or
allergy to the beta-blocker drug prescribed. Also tell your
health care professional if you are allergic to any other substances, such
as foods, preservatives, or dyes.
Pregnancy care
Use of some beta-blockers during pregnancy has been
associated with low blood sugar, breathing problems, a lower heart rate and
low blood pressure in the newborn infant. Other reports have not shown unwanted
effects on the newborn infant. Animal studies have shown some beta-blockers
to cause problems in pregnancy when using in doses many times the usual human
dose. Before taking any of these medication, make sure your family doctor knows if
you are pregnant or if you may become pregnant.
Breast-feeding problem
It is not known whether bisoprolol, carteolol,
or penbutolol passes into breast milk. All other beta-blockers pass into breast
milk. Problems such as slow heartbeat, low blood pressure and trouble in
breathing have been reported in nursing babies. Mothers who are taking beta-blockers
and who wish to breast-feed must discuss this with their family doctor.
Use for Children
Some of these medication have been using in child
and, in effective doses, have not been shown to cause various side effects
or problems in child than they do in adults.
Elderly care
Some side effects are more likely to occur in the
elderly, who are usually more sensitive to the effects of beta-blockers. Always
beta-blockers may reduce tolerance to cold temperatures in elderly diseaseds.
Drug interactions

together at all, in other cases two various medication may be using together
even if an interaction might occur. In these cases, your family doctor may want to
change the dose, or other precautions may be necessary. When you are taking
