It is impossible for your healthcare provider to know whether you will develop insomnia while taking Sarafem. Also, in some cases, if a person does develop insomnia, it is difficult to know whether these problems are because of other conditions or due to Sarafem itself.
If you develop insomnia while taking Sarafem, make sure to talk with your healthcare provider. There are other treatments that he or she may recommend, such as adjusting the Sarafem dosage or trying another medicine.
