In light of continuing complaints of quality issues involving certain prescription birth control pills, Health Canada is reminding women to check their packages of birth control pills. If you notice anything unusual in the package, such as missing or damaged pills, you should return the package to the pharmacy for replacement as soon as possible. Skipping a dose because the pill is missing, or taking a damaged (for example, chipped or fragmented) pill, may increase the risk of pregnancy because less active ingredient may be taken. It is important to get a replacement package as soon as possible to avoid missing any doses.
