While much medical advice has been given to prevent DVT, the ingestion of ASA (aspirin) has broader health implications which must be considered and risks mitigated. ASA does interfere with platlet aggregration by effectively destroying the megakeriocites. The net effect is that it will take a period of time (weeks) to resupply the bloodstream with the precursors to platlets. (assuming a 2 tablet dose of ASA BID. DVT is still quite rare and there are more important health ramifications to this drug regimine. I would highly suggest you visit your underpaid and underappreciated health care professional before imbarking on any long-term ASA usage. (for the people who live in the air)
