Restless Leg Syndrome Message Board

Restless Leg Syndrome Board Index

I've read on other message boards that quinine makes people dizzy and that there can be all sorts of side effects. How is that possible? Isn't tonic/quinine water just carbonated water with a very,very weak amount of quinine in it? I'll pretty much try anything to stop RLS but I like to know what to expect ahead of time. Hmmmm . . . I'm extremely sensitive to all drugs and even caffeine and things that never bother anyone so maybe a little research . . .

Went back out to the web to see what I could find about quinine and came back with this:

Quinine is a naturally occurring alkaloid (caffeine is another common alkaloid) isolated from the bark of several species of Cinchona trees. It gives beverages such as tonic water and bitters their distinctive flavor. Once considered potentially dangerous, quinine in tonic water is thought to be safe. In fact, consumers seeking the distinctive flavor of quinine report that there are no adequate alternatives to the real thing.

As with so many ingredients, dose really does make the poison. At very low levels (up to 83 PPM) quinine is a flavor. At higher levels (167 to 333 milligrams three times per day), it has been used to effectively treat malaria, digestive problems, heart palpitations, hemorrhoids, varicose veins, and leg cramps. [U][B]It is important to note that to achieve a therapeutic dose of quinine from tonic water, a person would have to drink between 6 and 12 quarts in a 24-hour period. [/B] [/U] And even at this amount, quinine would not necessarily cause problems, because individual reactions to it are quite variable. At higher levels than those allowed in beverages, quinine does have the potential to cause side effects such as rashes, itching, nausea, ringing of the ears, dizziness, headaches, and even birth defects. (These problems disappear when use is discontinued).

In sum, normal consumption of tonic water appears to be safe. If an individual were to consume excessive amounts, then problems could arise. But to put things into perspective, the estimated fatal dose of quinine is 25 times that of the amount approved for use in beverages. To get such a dose, a person would have to drink [B][I]25 quarts of tonic water in one sitting[/I][/B]!


[B]Guess I shouldn't worry about side effects for one or two 10 oz. bottles each night, should I? Ha! Here's hoping it works! [/B] ;)
