41 yo female pregnant after first IVF (2 mcs w/ no ivf) - is clexane necessary, and if so for how long? Risk of birth defects?

What's . Like all meds, ask the doc prescribing if you don't know what it's for or proper dosing. I'm sorry i'm not familiar with.
Work up needed. Two or more losses would constitute a diagnosis or recurrent pregnancy loss. That warrants a workup. If the evaluation shows a clotting problem, then the clexane may be indicated.

It depends. Someone with 2 or more losses is classified as having recurrent pregnancy loss. A full evaluation for rpl would be done to determine the underlying cause(s) of the losses. Clexane would be prescribed if/when an appropriate clotting issue is uncovered. Read more...
Depends on MC tests. Clexane is enoxaparin, a form of heparin, and is an anticoagulant or 'blood thinner'. It does not cause birth defects - Heparin can't cross the placenta to get into baby's blood, and it is pregnancy category b for safety, with no evidence of harmful effects on the baby in pregnant women. Do you need it & for how long depends on what your miscarriage tests found. Talk to your md. Congrats on preg! Read more...
