In 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. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes. However, pyrvinium has not been reported to cause birth defects or other problems in humans.
Older children are more likely to have stomach upset after receiving large doses.
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 pyrvinium 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. 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. The presence of other medical problems may affect the use of pyrvinium.
