What is the most important information I should know about hydroxychloroquine (Plaquenil)?
You should not use this medication if you are allergic to hydroxychloroquine, or if you have a history of vision changes or damage to your retina caused by hydroxychloroquine or similar anti-malaria medications.
Before using hydroxychloroquine, tell your doctor if you are allergic to any drugs, or if you have psoriasis, porphyria, liver disease, alcoholism, or glucose-6-phosphate dehydrogenase (G-6-PD) deficiency.
Call a poison control center at once and then seek emergency medical attention if you think you have used too much of this medicine. An overdose of hydroxychloroquine can be fatal, especially in children.
Take this medicine for the full prescribed length of time for malaria. Your symptoms may improve before the infection is completely cleared.
Contact your doctor as soon as possible if you have been exposed to malaria, or if you have fever or other symptoms of illness during or after a stay in an area where malaria is common.
When treating lupus or arthritis, tell your doctor if your symptoms do not improve after 6 months of treatment.
While using hydroxychloroquine, you may need frequent blood tests at your doctor's office.
