Tigecycline generics may not be readily available in local pharmacies due to patent protection. The drug is still under patent protection until 2025, as indicated by Drug Patent Watch [1]. This protection prevents the entry of generic versions into the market, limiting accessibility and potentially keeping prices higher. The Maryland Department of Health's Preferred Drug List [3] may also reflect this limited availability, as tigecycline generics are not commonly listed as preferred options. Therefore, patients seeking tigecycline may primarily find the brand-name version in local pharmacies due to patent exclusivity.
