My 17 year old daughter has heterozygous factor V Leiden,Cardiolipin IgG and Protenaise C. She will be making a long haul flight of 8 hours then 14 hours immediately.She then stays in Barcelona for three days ,then a two hour flight to Santiago.She is there for two weeks then does the same trip back home.We have had conflicting advise as to how many clexane injections to use and when.She had full length grade 2 pressure stockings.This is all prophylactic as there has been a history of blood clots and PE in the family. Please can you assist me. Thank you Jacqueline
Hi, dairy have gone through your question. I can understand your concern.  She has high chance of clotting. She needs prophylactic warfarin therapy.  Dosage depends on her INR level. She should maintain her INR between 2 and 3. Consult your doctor and DET the dosage accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
