Nebenwirkungen (noun, plural)
A compound noun meaning ‘side effects’; it is plural, so the accompanying verb must be in the third‑person plural or the existential construction.

Also, Germans tend to be very precise about side‑effect information, so asking this question is considered responsible and appreciated.
