Additional Details
Is Glycerol Safe? Are There Any Warnings?
Safety: Glycerol is generally safe when used rectally, topically, and orally in appropriate amounts. However, caution should be exercised when using intravenous glycerol, and it is prohibited by the World Anti-Doping Agency (WADA) due to its potential to mask blood doping.
Adverse Effects: Glycerol is well tolerated orally, rectally, and topically. The most common side effects include bloating, diarrhea, nausea, vomiting, dizziness, headache, burning, irritation, and pruritus. Intravenous use of glycerol may lead to hemolysis in patients with acute ischemic stroke.
How Is Glycerol Thought To Work? What Is the Mechanism of Action?
Mechanism of Action: Glycerol is a naturally occurring trivalent alcohol that serves as a backbone for triglycerides in the body. It has various effects:
- Glycerol has hydration effects when applied topically, preventing water loss and acting as a humectant in moisturizers.
- In patients with meningitis, glycerol's benefits may be due to its effect on osmolality, reducing cerebrospinal fluid loss, enhancing cerebral circulation, and reducing inflammation by scavenging free radicals.
- Glycerol has demonstrated hyperosmotic laxative activity, promoting bowel movements.
- When used rectally, glycerol can help with constipation in both children and adults.
- Oral glycerol may improve hydration during exercise, but its effects on athletic performance are limited and conflicting.
