Side effect timeline for injection-site reactions based on my experience and tracking:

Most side effects are transient and self-limiting. The key is pushing through the first month — it gets dramatically better.

Injection site reactions and injection-site reactions: I was getting red, itchy welts at every injection site that lasted 3-4 days. Turned out I was allergic to the alcohol swab, not the medication!

Switched to chlorhexidine prep pads and the reaction stopped completely. If you're having persistent injection site reactions, consider this possibility before blaming the drug.

Nurse here. I see both sides of injection-site reactions in my clinical practice.

I manage about 98 patients on GLP-1 agonists at our weight management clinic. The most common issue I see related to injection-site reactions is patients not being adequately informed about what to expect. Setting realistic expectations up front is everything.

Practical tips from the clinic floor:
• Rotate injection sites religiously — use a log
• Let the alcohol dry COMPLETELY before injecting
• Don't massage the injection site
• Keep medication refrigerated until use, then room temp is fine for up to 28 days

This matches mine closely enough to be worth saying so out loud.
