Table 1. From ACCP guidelines 2012: when describing the various regimens of UFH and LMWH, the ACCP recommends the following short forms.

Adjusted dose UFH	UFH subcutaneously every 12 h in doses adjusted to target a midinterval activated partial thromboplastin time (aPTT) into the therapeutic range
Prophylactic LMWH	For example, dalteparin 5,000 units subcutaneously every 24 h, tinzaparin 4,500 units subcutaneously every 24 h, nandroparin 2,850 units subcutaneously every 24 h or enoxaparin 40 mg subcutaneously every 24 h. At extremes of body weight, modification of dose may be required
Intermediate dose LMWH	For example, dalteparin 5,000 units subcutaneously every 12 h or enoxaparin 40 mg subcutaneously every 12 h
Adjusted dose LMWH	Weight adjusted or full treatment doses of LMWH given once daily or bid. For example, dalteparin 200 units/kg or tinzaparin 175 units/kg once daily or dalteparin 100 units/kg every 12 h or enoxaparin 1 mg/kg every 12 h
