Lastacaft and Pregnancy
Based on the results of animal studies, Lastacaft (alcaftadine) is considered a pregnancy Category B medicine. This means that it is probably safe for use by women who are expecting. When extremely high doses of Lastacaft were given to pregnant animals, it did not appear to cause fetal harm. However, your healthcare provider will weigh the benefits and risks in your particular situation.
I'm Pregnant -- Can I Use Lastacaft?Lastacaft™ (alcaftadine) is a prescription antihistamine medication approved to treat eye allergy symptoms. It is probably safe for use during pregnancy, although the full risks are currently unknown.
What Is Pregnancy Category B?The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category B is given to medicines that have not been adequately studied in pregnant humans, but do appear to be safe in animal studies.
Also, medications that have been shown to be safe for use in pregnancy in humans but have caused problems in laboratory animals are given a Category B rating.
Although Lastacaft has not been studied in pregnant humans, animal studies suggest that the drug is unlikely to cause fetal harm. Even when extremely high doses of Lastacaft were given to pregnant rats and rabbits, it did not appear to cause problems.
However, it is important to note that animals do not always respond to medicines in the same way that humans do. Therefore, a pregnancy Category B medicine should be given to a pregnant woman only if the healthcare provider believes that the benefits to the woman outweigh any possible risks to the unborn child.
Final ThoughtsIf you are pregnant or are thinking about becoming pregnant, let your healthcare provider know before using Lastacaft. He or she will consider the benefits and risks before making a recommendation in your particular situation.
