What happens if I overdose?

Get immediate medical help or dial 1-800-222-1222 for poison help. A hydroxychloroquine overdose needs to be treated right away because it can be fatal.

Drowsiness, altered vision, seizures, a weak pulse, pounding heartbeats, sudden dizziness, fainting, shortness of breath, or slow breathing are just a few of the overdose symptoms that can occur (breathing may stop).

Keep hydroxychloroquine away from young people. A child who unintentionally takes too much hydroxychloroquine could die.
