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 ketotifen, the following should be considered:
Allergies - Tell your doctor if you have ever had any unusual
or allergic reaction to ketotifen. Also tell your health care professional
if you are allergic to any other substances, such as foods, preservatives,
or dyes.
Diet - Make certain your health care professional
knows if you are on any special diet, such as a low-sugar diet. The syrup
contains carbohydrates.
Pregnancy - Ketotifen has not been studied in pregnant women.
However, studies in animals have shown that ketotifen crosses the placenta
and, at high doses, cause problems. Before using this medicine, make sure
your doctor knows if you are pregnant or if you may become pregnant.
Breast-feeding - It is not known whether ketotifen passes into
human breast milk. However, it does pass into the milk of rats. It may be
necessary for you to take another medicine or to stop breast-feeding during
treatment. Be sure you have discussed the risks and benefits of the medicine
with your doctor.
Children - This medicine has been tested in children and,
in effective doses, has not been shown to cause different side effects or
problems than it does in adults.
Older adults - Many medicines have not been studied specifically
in older people. Therefore, it may not be known whether they work exactly
the same way they do in younger adults or if they cause different side effects
or problems in older people. There is no specific information comparing use
of ketotifen in the elderly with use in other age groups.
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 ketotifen, it is especially important
that your health care professional knows if you are taking any of the following:
