Is it ok to save money by opening a 20 mg capsule of fluoxetine, dumping about half in a glass of water and saving the capsule for the next day with the remainder? In other words, does fluoxetine mixed in water have any adverse affects? And if I don't get an exact measurement isn't it probably ok since fluoxetine has such a long half life?
