Ask your doctor: The doctor who prescribed these meds is properly the one to ask. In fact, he/she may be highly annoyed with you upon finding out that you asked a lot of remote-access doctors who don't have a doctor-patient relationship with you instead of him/her. This is not really responsible behavior. Don't be afraid to call your doc and ask. He/she would want you to. If he/she doesn't, find another doctor.
