Can switching to warfarin from heparin before knowing I was pregnant cause high risk pregnancy?

Can switching to warfarin from heparin before knowing I was pregnant cause high risk pregnancy?

Warfarin: Warfarin is a drug you shouldn't be using during pregnancy. Heparin is safer because it doesn't cross the placenta and affect the fetus. But why do you need these anticoagulants? That cause may increase the risks of pregnancy and put you into a high risk group. Talk to your doctor. ...Read more

My thrombosis specialist is having me switch from warfarin to lmwh as soon as i get a positive pregnancy test. At 4 weeks, is this ok?

My thrombosis specialist is having me switch from warfarin to lmwh as soon as i get a positive pregnancy test. At 4 weeks, is this ok?

Yes!: Warfarin is not good to take during pregnancy as it can cause birthdefects, lmwh does not have this problem and can be safely used during pregnancy. I would strongly suggest that you seek an opinion from an OB or highrisk pregnancy doctor to be sure you are doing all that they would recommend to have a healthy pregnancy. ...Read more

I got a pulmonary embolism after my pregnancy, and im on warfarin right now. Is it ok and safe to go on rollercoasters?

I got a pulmonary embolism after my pregnancy, and im on warfarin right now. Is it ok and safe to go on rollercoasters?

Basically - Yes: Patients with a recent DVT (or pe) who are on anticoagulant treatment are at low risk of further clots. If taking coumadin, inr must be at goal (2-3). Coumadin increases risk of bleeding so contact sports are often discouraged. Roller coasters are probably not in the same category as full contact football but you certainly can get knocked around a bit. The risk would be bruising though - not pe. ...Read more

First pregnancy was complicated with pe at 33 weeks, again 4wk after c/s what is your advised on a second pregnancy diagnosis prot s deficiency, on wafarin ?

Risky: Further pregnancy in the face of previous pulmonary embolism is risky as pregnancy itself makes the blood more likely to clot. Most physicians would advise against but if it happens, your doctor will probably switch you to lovenox. Warfarin use is considered contraindicated in pregnancy due to potential effects on the unborn child. ...Read more

How risky is attempting pregnancy at the age of 40, mild lupus, antiphospholipid antibody syndrome currently taking coumadin?

How risky is attempting pregnancy at the age of 40, mild lupus, antiphospholipid antibody syndrome currently taking coumadin?

Risks are low!: I do not see major risks in becoming pregnant, that is if you get pregnant. You will be switched to heparin, probably once daily lovenox. But your lupus can be managed successfully during pregnancy, and the hughes syndrome should be a non-issue if on an anticoagulant. Hope you achieve your goal! ...Read more

What are th chances of a recurring pe or clot after 6 months on warfarin and other wise healthy 21 y/o?

What are th chances of a recurring pe or clot  after 6 months on warfarin and other wise healthy 21 y/o?

10+%: Depending on which study you look at, the risk is at least 10% even if the pe was provoked by a transient factor (immobility, pregnancy etc). Data shows that indefinite anticoagulation significantly decreases the risk of subsequent pe but at an increased risk of bleeding. ...Read more
