Is it lawful for some English NHS trusts to stock more kinds of medications than others?
<h3>Factual Situation</h3>
<p>My daughter lives in an area covered by a NHS Trust beneath that's not Oxford. Her migraine can be only treated with a triptan on Oxford's formulary, but not her own area's, like Eletriptan. His GP said that he can't prescribe her a triptan on Oxford's formulary. The only way she can get it, is if she's admitted to their ER or is eligible for Oxford NHS. But she isn't.</p>
<h3>Legal Question</h3>
<p>Isn't it discriminatory for some UKers to have more triptans, and thus better health care, by the NHS than others solely based on your address?</p>
