A message from the Executive Director

Dear Supporter,

The term "quinism" may seem new, but no doubt the symptoms of poisoning by mefloquine (previously marketed as Lariam®), tafenoquine (marketed as Krintafel® and Arakoda™), and related quinoline drugs are all too familiar: Tinnitus. Dizziness. Vertigo. Paresthesias. Visual disturbances. Gastroesophageal and intestinal problems. Nightmares. Insomnia. Sleep apnea. Anxiety. Agoraphobia. Paranoia. Cognitive dysfunction. Depression. Personality change. Suicidal thoughts.

These symptoms are not 'side effects'. They are symptoms of poisoning by a class of drug that is neurotoxic and that injures the brain and brainstem. Poisoning that causes a disease.

This disease has a name. The disease is chronic quinoline encephalopathy — also known as neuropsychiatric quinism.

The Quinism Foundation is a Vermont domestic 501(c)(3) nonprofit charitable organization established to support education and research on chronic quinoline encephalopathy and other medical conditions caused by poisoning, or intoxication, by mefloquine, tafenoquine, and related quinoline drugs.

The foundation has an enormous job ahead. We must prepare healthcare organizations to identify those exposed to quinolines and to screen for symptomatic quinoline exposure. We must educate clinicians to diagnose chronic quinoline encephalopathy and other medical conditions caused by quinoline poisoning. We must train researchers to distinguish the effects of quinism from those of other disorders, including Post-traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI). We must assist government agencies to recognize those suffering disability from quinism. We must identify risk factors for the disease. We must attempt to count all those affected. And, we must support a search for effective treatments.

On behalf of The Quinism Foundation, I thank you in advance for your support. I am confident that together, we can make a difference in the fight against quinism. I hope that you will join us.
