text: where can i buy the medicine called prednisolone on line? for skin conplaints. prednisilone is a steroid.  have you been prescribed this by a doctor?  it can be purchased online, but you will need a doctor's prescription.  if you don't have one, they will have you complete a form, which will then be reviewed by a doctor before issuing the prescription.  be very careful with steroids a they can cause a lot of damage to you if not taken and stopped correctly.
