    Plaquenil induced hyperpigmentation


    One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine (Plaquenil), a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus.

    Conclusions HCQ-induced pigmentation is considered uncommon adverse effect of HCQ, with a prevalence rate of 49.2% indicated in this study. Furthermore, history of bruising, sun exposure, and the presence of mucous membrane pigmentation are possible predisposing factors. Drug-induced skin pigmentation accounts for 10–20% of all cases of acquired hyperpigmentation. Pigmentation may be induced by a wide variety of drugs; the main ones implicated include non-steroidal anti-inflammatory drugs NSAIDs, phenytoin, antimalarials, amiodarone, antipsychotic drugs, cytotoxic drugs, tetracyclines, and heavy metals. Many systemic medications may cause retinal toxicity.

    It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress.

Dermatologic side effects have included mucocutaneous hyperpigmentation, nonlight-sensitive psoriasis, bleaching of hair, alopecia, pruritus, photosensitivity, and skin eruptions such as urticarial, morbilliform, lichenoid, maculopapular, purpuric, erythema annulare centrifugum, Stevens-Johnson syndrome, acute generalized exanthematous pustulosis, and exfoliative dermatitis.

    Cutaneous pigmented lesions were found in 21 cases 51%, mucous pigmentation in 5 cases 12% and nail pigmentation in 1 case 2.5%. In 12 of 41 29% of the hydroxychloroquine users, we conclude a hydroxychloroquine-induced pigmentation. We report two cases of hydroxychloroquine‐induced hyperpigmentation presenting in a 50‐year‐old Caucasian female case 1 and a 78‐year‐old female case 2, both receiving 400 mg per day. Case 1 had an arthritis predominant undifferentiated connective tissue disease, which was treated with hydroxychloroquine for 4–5 years. Importance Hydroxychloroquine-induced pigmentation is not a rare adverse effect. Our data support the hypothesis that hydroxychloroquine-induced pigmentation is secondary to ecchymosis or bruising.

    Malaria meds for Paksitan - Chloroquine vs Malarone. Chloroquine is not effective in Pakistan. Ten malaria parasites have become too resistant to it. Mefloquine Lariam, Mefliam, Mephaquin and many others, doxycycline Vibramycin and many others, and atovaquone/proguanil Malarone, Malanil are all effective.
