Dr. Hanif warmly Welcomes you! Thanks for consulting at my virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. Yes its a good anticoagulant (prevents platelte aggregation in body). It has a more benefit as a prophylaxis after surgeries to prevent a blood clot from forming. And also in conditons like atrial fibrillation. You need to take it almost 10weeks. Dont miss even a single dose. Don t stop taking it immediately, otherwise it will cause more serious blood clots. Hope it helps you. If you need further, detailed and quick assistance related to any health issues, feel free to ask me a question directly from my profile.
