<prompt> As compared to unfranctioned heparin, low molecular weight heparinsAre absorbed more uniformly when given subcutaneouslyRequire more frequent laboratory monitoringCan be given to patients with heparin induced thrombocytopeniaPredispose to higher risk of osteopenia  <response>: Refer Katzung 10e p 546 Unlike unfranctioned heparin, LMW heparins have more consistent SC bioavalilabilty and thus do not require monitoring Adverse effects of both type of heparins are similar Both are contraindicated in heparin induced thrombocytopenia
