  • Signs of infection at an injection site.
  • Any new or unexplained symptom you would ordinarily see a doctor about.

Not approved for human use in the United States. Development as an obesity treatment was discontinued after trials failed to show benefit. Sold as a research chemical and — in some markets — marketed in ways that do not reflect that outcome.
