Your question leaves out too much to give a comprehensive answer, such as what type of medicine it is, what reason the MD stated for not refilling, what the condition is, etc. E.g., if this is a pain medication, which susceptible to abuse, the MD may worry that you're becoming addicted or abusing the meds, and need closer evaluation to justify refilling. The MD may have an obligation NOT to refill the meds in that case. You may wish to a) talk to your MD to get a clear answer for why no...
