Before Using This Medicine

In deciding to use a medicine, the risks of receiving the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For botulinum toxin type B, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to botulinum toxin type B or any other type of botulinum toxin. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy—Studies on effects in pregnancy have not been done in either humans or animals.

Breast-feeding—It is not known whether botulinum toxin type B passes into the breast milk. Although most medicines pass into breast milk in small amounts, many of them may be used safely while breast-feeding. Mothers who are taking this medicine and who wish to breast-feed should discuss this with their doctor.

Children—Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of botulinum toxin type B in children with use in other age groups.

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. Although there is no specific information comparing use of botulinum toxin type B in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.

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.
