On week 5 of ozempic and i developed a hot,tight, red,really itchy neck .some red dots on face too.i have this for a week now i am due to take ozempic today and concerned if it may be ozempic causing it.should i take my ozempic?

Allergic reaction may be a side effect of ozempic but it's not just localized on the neck and face. If I was your doctor & ozempic is used for weight loss, I would recommend to hold it for one week & observe. If after 3-4 days the current symptoms aren't subsided or getting worse then ozempic isn't the culprit. If med is used for DM, then other meds & diet need to be adjusted for glycemic control.
