I'm 28, no past hx. Do not smoke, no birth control. Have DVT in calf after car accident. How likely is it to get another blood clot while on lovenox (enoxaparin)?

Not likely. possible, but not likely. This was a provoked DVT and the treatment is usually for 3 months. If you notice skin changes and or new onset leg swelling while on Lovenox (enoxaparin) let your doc know as soon as possible. Heparin induced thrombocytopenia is a rare complication of heparin or low molecular weight heparin treatment that may result in venous or arterial thrombosis.
