"hi i started saxenda on july 27,2016. in those 5 weeks i lost 13lbs. starting weight was 229.  my common side effect is nausea and a little constipation. i would recommend this drug for anyone that trying to eat healthy, exercise and lose weight to get back on track. i was on dosage 3.0 for a week and had to drop back down to 2.4 because i was so nauseated. it does decrease your appetite but you still need to eat and make sure you drink plenty of water.  i don&#039;t like the fact when you injected the medicine in your upper thigh is leaves a bruise, never have a mark on my stomach. good luck"
