Fetal warfarin syndrome appears in greater than 6% of children whose mothers took warfarin during pregnancy. [3] Warfarin has a low molecular weight so can pass from the maternal to fetal bloodstream through the tight filter-like junctions of the placental barrier. As the teratogenic effects of warfarin are well known, the medication is rarely ...
Warfarin (brand name Coumadin) is a commonly prescribed blood thinner both in the inpatient and outpatient hospital settings. In pregnant women, warfarin is contraindicated and should be avoided as it crosses the placental barrier. Additionally, warfarin is listed as Pregnancy Category D, which means it has a risk of harming the fetus. [37]
Major side effects of tinzaparin are osteoporosis (occurring in up to 1% of cases), thrombocytopenia (heparin-induced thrombocytopenia), haemorrhage, hair loss and drug allergy. [13] Still, LMWHs are much less likely to cause heparin-induced thrombocytopenia than unfractionated heparin. [13]
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
Warfarin should not be given to people with heparin-induced thrombocytopenia until platelet count has improved or normalised. [39] Warfarin is usually best avoided in people with protein C or protein S deficiency, as these thrombophilic conditions increase the risk of skin necrosis, which is a rare but serious side effect associated with ...
Apart from using unfractionated heparin instead, it may be possible to reduce the dose and/or monitor the anti-Xa activity to guide treatment. [3] The most common side effects include bleeding, which could be severe or even fatal, allergic reactions, injection site reactions, and increases in liver enzyme tests, usually without symptoms. [13]
Common side effects include bleeding, fever, and swelling of the legs. [11] Bleeding may be serious especially in those who are undergoing a spinal tap. [11] Use during pregnancy appears to be safe for the baby. [11] Enoxaparin is in the low molecular weight heparin family of medications. [11]
Protamine sulfate is a medication that is used to reverse the effects of heparin. [3] It is specifically used in heparin overdose, in low molecular weight heparin overdose, and to reverse the effects of heparin during delivery and heart surgery. [3] [4] It is given by injection into a vein. [3] The onset of effects is typically within five ...
