Family member was put on crestor (rosuvastatin) but is having side effects: feet feel tight, fatigue, weakness,etc. go to er? getting worse. what will they do???

Contact doctor : Medication side effect is often concerning and in this case the class of medication called Statins. I will recommend calling the doctor that started the medicine and discussing this concerns as soon as possible. They are other options for treating cholesterol that can be explored. Thanks for advocating for family, we need more people like you.
