- ✓Effects become noticeable within hours to days post-treatment.
- ✓Mild side effects may include pain/redness or itching at the injection site and mild diarrhea, which typically subside over time.
- ✓Itching or a sensation of body-wide swelling may occur. If these effects persist or worsen, promptly inform your doctor. Serious side effects are uncommon for many using this medication.
