Although the incidence of macular toxicity is infrequent with Plaquenil use (at a dosage of 200mg or 400mg q.d.), its visual impact can be devastating. Can you get high on hydroxychloroquine Chloroquine resistant salmonella Plaquenil aao 2016 Newer guidelines state that daily dose 5mg/kg of real weight/day can lead to toxicity. Retinal toxicity is irreversible and can progress after cessation of hydroxychloroquine, thus early screening is important to limit potential vision loss. Baseline screening and annual screening after five years is recommended.

Lyons emphasizes the importance of annual screening and says that, although annual screening is recommended for everyone taking Plaquenil, it is imperative for people who have been taking the medication for more than 10 years, who have a higher incidence of retinal toxicity. Plaquenil-induced toxicity usually will not occur before five years of. Initially, central visual acuity may be unaffected, but the patient may notice related paracentral scotomas that often interfere with reading.
