It is possible that you may experience some or none of the Apri side effects listed in this article. Unfortunately, it can be difficult to tell whether any particular side effect (such as nausea) is caused by Apri or other factors. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking Apri, or if something "just does not seem right." While it may not be a side effect of Apri, your healthcare provider will be able to diagnose and treat the problem.
