How safe is heparin during pregnancy?

Requires care. Heparin, a blood thinner, can cause serious bleeding problems. While complications are rare, when they happen, they can be severe. Using Heparin requires expert care.
Depends. Agree with dr. Chenette that Heparin should be used with caution. If there is a good reason to use this medication (such as previous history of a DVT or recurrent pregnancy loss associated with antiphospholipid antibodies) then it can be used. Heparin does not cross the placenta so the impact on the pregnancy would relate to the risk of bleeding and also a risk of bone loss in the mother.

Is it safe to switch clexane for heparin? Pregnancy

Clexane. Clexane (known as Lovenox in the U.S.) is the brand name for enoxaparin. This medication is commonly used during pregnancy. Some doctors will switch back to unfractionated Heparin close to delivery since Heparin has a completely effective antidote, while enoxaparin's antidote is less reliable. Obviously, the OB doesn't want anyone to bleed excessively during delivery.

Heparin. According to my readings, both are effective but the calcium preparation causes more discomfort at the injection sites. A hematologist or even your pharmacist may be able to provide you with additional information regarding the 2 preparations and their differences.

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.
Yes. You'll need to switch back to Heparin in pregnancy or (lovenox). You don't give the reason for your anticoagulant so either a blood disorder, heart arrhythmia, artificial valve, or thrombo-embolic event (etc) will make you high risk in pregnancy. You will need an experienced OB or mfm specialist to monitor your levels, infant, & carefully plan your delivery. Take care.
