Is contraceptive ocp's for women with thrombocytopenia safe?

See your doctor. Oral conttraceptives can cause clotting, especially if combined with smoking. In patients with low platelets, this would be likely to be a good thing as they cannot clot well. However, previous thromboembolic disoreders is an absolute contraindication to ocp use so this could mean no use for low platelet patients. You would be wise to see your doctor.
