how long does a medrol injection in ankle last
HiCustomer Thank you for asking your question on JustAnswer. Depo-Medrol has a very long half life and remains in the body far longer than other steroid preperations. Several factors influence absorbtion and elimination times, but a single IM injection of 80 mg may remain in the system in trace amounts up to 28 days. Customer: replied 7 years ago. last question, are headaches a side effect of this injection, i never had them before i was given this. also why do they advise not to drink alcohol while on this.
