A new warning has been issued over quinine, a medicine and ingredient found in beverages like tonic water and bitter lemon.
Long used as a drug for malaria, quinine is no longer a recommended treatment for any condition by the U.K.’s two major healthcare watchdogs. However, that hasn’t stopped doctors in the country from issuing 3.5 million prescriptions for it every year to people who are suffering from issues like cramps, muscle discomfort and restless legs. Doctors are prescribing it off-label for such conditions, and in many cases, patients take it for several years.
Now, researchers from University College London and the Royal Free Medical School have discovered that people who take quinine for more than a year have a 25 percent higher likelihood of early death than those who do not take the drug. Interestingly, those who were younger than 50 had a greater rise in their risk of death than older patients.
The researchers studied those taking prescriptions for quinine of 100 milligrams a day or more over the course of a year or longer. Their findings were published in the Journal of the American Medical Association.
Quinine can cause an abnormal heart rhythm in some people, possibly triggering a heart attack. In addition, it can affect blood clotting, which could lead to a stroke or heart attack from a blocked artery.
Watch out for tonic water, too
While drinking a few gin and tonics here and there might not be problematic on its own, those who are already taking quinine as a medicine need to watch their intake because it could heighten their risk even further. In rare cases, even the small amount found in tonic water could be enough to cause one of quinine’s most serious side effects, a severe drop in blood platelet counts that can cause external and internal bleeding. Another worrying side effect is permanent kidney damage.
It is also worth noting that quinine passes through the placenta and can cause birth defects, which means that pregnant women should avoid it at all costs. In addition, it is known to interact with some common drugs like statins and the heart failure medication digoxin.
