Lovenox Dosing for Treating DVT ClotsThe standard dosage for treating DVT (without pulmonary embolism) in people who will be treated outside of a hospital is 1 mg per kg (about 0.45 mg per pound) every 12 hours. For treating DVT in the hospital (in people with or without pulmonary embolism), the standard dosing is 1 mg per kg (about 0.45 mg per pound) every 12 hours or 1.5 mg per kg (about 0.68 mg per pound) every 24 hours.
For DVT treatment, most people will also be started on warfarin (Coumadin®, Jantoven®), as warfarin is usually preferred as the long-term treatment. Lovenox should be continued for at least five days after the warfarin is started and only after laboratory tests show that the warfarin is working well enough.
Lovenox Dosing for "Cardiac Events"The standard dosage of Lovenox after an episode of unstable angina (a type of chest pain that may signal that a heart attack is near) or a non-Q-wave myocardial infarction (a type of mild heart attack) is 1 mg per kg (about 0.45 mg per pound) every 12 hours combined with aspirin (100 to 325 mg once daily). Lovenox should be given for at least two days and until the person is stabilized.
The standard dose of Lovenox after a "full-blown" heart attack, known medically as an ST-segment elevation myocardial infarction (STEMI), is a single 30 mg dosage given intravenously (by IV), followed immediately by a dose of 1 mg per kg (about 0.45 mg per pound) injected the usual way (just under the skin) and continued every 12 hours, in combination with aspirin. Your healthcare provider may adjust the timing and/or dosage depending on your unique situation (and whether other treatments are planned). It should be noted that lower doses (and no initial IV dose) is usually recommended for this use in people age 75 years old or older.
