Before Using This MedicineIn deciding to use a medicine,
the risks of taking the medicine must be weighed against the good it will
do. This is a decision you and your doctor will make. For ritodrine, the following
should be considered:
Allergies - Tell your doctor if you have ever had any unusual or
allergic reaction to ritodrine or sulfites. Also tell your health care professional
if you are allergic to any other substances, such as foods, preservatives,
or dyes.
Other medicines - Although certain medicines should not be used
together at all, in other cases two different medicines may be used together
even if an interaction might occur. In these cases, your doctor may want to
change the dose, or other precautions may be necessary. When you are taking
or receiving ritodrine, it is especially important that your health care professional
know if you are taking any of the following:
-
Beta-adrenergic blocking agents (acebutolol [e.g., Sectral], atenolol
[e.g., Tenormin], betaxolol [e.g., Kerlone], bisoprolol [e.g., Zebeta], carteolol
[e.g., Cartrol], labetalol [e.g., Normodyne], metoprolol [e.g., Lopressor],
nadolol [e.g., Corgard], oxprenolol [e.g., Trasicor], penbutolol [e.g., Levatol],
pindolol [e.g., Visken], propranolol [e.g., Inderal], sotalol [e.g., Sotacor],
timolol [e.g., Blocadren]) - Ritodrine may be less effective if it is
used with any of these medicines
-
Corticosteroids (cortisone-like medicines) - These medicines
are often given together to the mother to help her baby's lungs develop. If
you are taking corticosteroids, your dose may need to be changed if ritodrine
is also taken or injected. Sometimes the combination of these medicines increases
the chance of side effects occurring in the mother.
-
Medicine for asthma or breathing problems - Because these products
have some effects that are similar to those of ritodrine, the chance of side
effects developing is increased when these medicines are used with ritodrine
Other medical problems - The presence of other medical
problems may affect the use of ritodrine. Make sure you tell your doctor if
you have any other medical problems, especially:
-
Diabetes mellitus (sugar diabetes) - Ritodrine may make this
