deep vein thrombosis
"I've been taking Xarelto for 5 months for a blood clot brain . I've felt a range of side effects including : dizziness/vertigo, headaches, photosensitivity, lesions on my nose, ear and tongue, sinusitis, nausea, diarrhea, HEAVY menstrual bleeding, and general aches/fatigue. Basically, any kind of infection I get is much worse than it would be normally. I haven't had any major bleeding events, but my periods have been debilitatingly heavy.
As far as effectiveness, it has worked for me and I have not developed any further clotting, which is the most important thing. Not sure if other blood thinners are as effective and have less severe side effects, but if they are, it probably would've been worth the extra trips to the doc for me."
