Does Tonic Water Really Stop Eye Twitching? The Truth
Tonic water contains quinine, which may help reduce eye twitching for some, but it’s not a guaranteed or primary treatment; consult a doctor for persistent issues.
Eye twitching, or eyelid myokymia, is a common but annoying condition. Many people swear by tonic water as a remedy. But does it actually work? Let’s examine the science behind this claim.
What Causes Eye Twitching?
Eye twitching occurs when the orbicularis oculi muscle in your eyelid contracts involuntarily. While usually harmless, it can be frustrating. Common triggers include:
- Stress and anxiety
- Fatigue
- Excess caffeine
- Eye strain
- Nutritional deficiencies
Most cases resolve on their own within days. Chronic twitching may last weeks or months. For severe cases, doctors sometimes recommend botulinum toxin injections.
The Tonic Water Claim
Tonic water contains quinine, a compound with muscle-relaxing properties. Some believe quinine can calm twitching eyelid muscles. But is there any truth to this?
How Quinine Works
Quinine blocks acetylcholine receptors at neuromuscular junctions. This mechanism has shown effectiveness for nocturnal leg cramps at doses of 200-500mg daily.
However, tonic water contains only about 83mg of quinine per liter – far below therapeutic levels. You’d need to drink dangerous amounts to reach medicinal doses.
What Research Says
No clinical studies support tonic water for eye twitching. The FDA warns against using quinine for muscle cramps due to potential side effects like:
- Hearing loss
- Tinnitus
- Tremors
- Ataxia
A 2015 review found quinine effective for leg cramps, but at much higher doses than found in tonic water.
Better Alternatives for Eye Twitching
Instead of tonic water, try these evidence-based approaches:
Lifestyle Changes
- Reduce caffeine intake
- Get more sleep
- Practice stress management
- Use warm compresses
Nutritional Support
Certain deficiencies may contribute to twitching. Consider:
- Magnesium supplements
- Potassium-rich foods
- B-complex vitamins

The Bottom Line
While tonic water contains small amounts of muscle-relaxing quinine, there’s no scientific proof it stops eye twitching. The quinine dose in tonic water is too low to be effective, and drinking large amounts could be harmful.
Focus instead on reducing stress, improving sleep, and addressing nutritional needs. If twitching persists for weeks, consult an eye doctor. For most people, eyelid twitching resolves on its own with time and self-care.
