My experience is with semaglutide only (ozempic and wegovy)
COST - Both my husband and mother take ozempic for their diabetes and it is covered by insurance. My mother has Medicare with Humana and currently pays about $45 for a 4 dose pen. My husband is charged a $25 co-pay for the same pen. No insurance plan in my state covers GLP-1 drugs to treat obesity without being a diabetic so I paid $500 per month for wegovy for myself since I am severely obese. This price is unsustainable for us .. so here I am.
SIDE EFFECTS - All of us followed the recommended method of starting with a low dose and then stepping up gradually. My husband, who has never been overweight, has had no side effects at all. Ozempic is doing a fantastic job controlling his diabetes. My mother, who is obese, has only recently complained of stomach discomfort after several months taking the 1 mg dose. I have a hard time pinning the issue solely on the drug due to many other possible causes that my mother is dealing with. Hard to say with her. She's in her mid 70s and not doing the best job of taking care of herself. As for me .. I had some cramping with bowel movements at the lowest dose. I think it happened maybe 4 times in total. It wasn't too bad really. Certainly nothing that would make me want to give up .. it just encouraged me to drink more water and to try adding more fiber to my diet. I am currently at the 0.5 dose and doing well.
WEIGHT LOSS - My mother lost 30+ pounds in 8 months or so. My husband lost no weight, but he didn't need to lose any. I have lost 17 pounds in 2 months.
