Understanding the Active Ingredient: Lidocaine
Lidocaine, the active ingredient in Glydo, is a topical local anesthetic that works by temporarily blocking nerve signals in the area where it is applied. This action prevents pain and numbing sensations. In the context of hemorrhoids, anal fissures, and other anorectal conditions, lidocaine can provide significant, temporary pain relief. However, the key to safe and effective use is selecting the correct formulation and following the specific application instructions for that product.
Glydo Gel: Formulated for External Skin Application
Glydo gel, like many other standard topical lidocaine products, is specifically designed for application to external skin. Its formulation and packaging are suited for conditions like sunburn, minor burns, insect bites, or other superficial skin irritations. The gel's consistency and concentration are not optimized for the mucous membranes of the rectum. Applying a non-rectal product internally can lead to several issues, including improper dosage, increased risk of systemic absorption, and potential irritation from non-rectal ingredients.
Why You Shouldn't Use Glydo Rectally
- Increased Systemic Absorption: The mucous membranes in the rectum can absorb medication much more readily than external skin. Using a product with a higher concentration or a formulation not intended for this site could lead to excessive absorption of lidocaine into the bloodstream, increasing the risk of systemic side effects.
- Improper Packaging: Glydo does not come with a rectal applicator, and using a finger or other non-sterile device can introduce bacteria and cause further irritation or infection.
- Risk of Overdose: When used off-label, it is difficult to measure the correct dosage, increasing the risk of an overdose, especially for repeated use.
Specialized Lidocaine Products for Rectal Use
For anorectal pain, many lidocaine products are specifically designed for rectal application. These products often combine a local anesthetic with a corticosteroid, such as hydrocortisone, to reduce both pain and inflammation. These items are specifically formulated for safe use on the delicate tissues of the anus and rectum and often include a rectal applicator for controlled, hygienic application.
Common Rectal Lidocaine Products:
- Prescription Gels and Creams: Products like lidocaine/hydrocortisone rectal gel are prescribed for conditions like hemorrhoids and anal fissures.
- Over-the-Counter Options: Some over-the-counter creams, such as RectiCare Anorectal Cream (5% lidocaine), are explicitly labeled for anorectal use.
- Combined Ointments: Other products, like some Xylocaine ointments, are specifically formulated and approved for hemorrhoid and anal fissure relief.
Comparison: Glydo vs. Rectal Lidocaine Products
| Feature | Glydo (Standard Topical Lidocaine Gel) | Specialized Rectal Lidocaine Product |
|---|---|---|
| Primary Indication | Minor skin irritations (burns, insect bites) | Anorectal pain, itching, and inflammation (hemorrhoids, fissures) |
| Application Site | External skin surfaces only | Perianal area and internal rectum (as directed) |
| Formulation | Standard topical gel, sometimes with cooling agents | Specially formulated gel or cream, often with hydrocortisone |
| Packaging | Tube or sterile pak, no rectal applicator | Tube with a specific rectal applicator included for safe insertion |
| Absorbability | Less systemic absorption expected on intact skin | Higher potential for systemic absorption via mucous membranes; specially formulated for safety |
| Risk of Misuse | High risk if used internally due to formulation and packaging | Minimal risk if used as directed with the proper applicator |
Proper and Safe Rectal Lidocaine Application
For products specifically designed for rectal use, proper application is critical to both safety and efficacy. Always follow the instructions provided on the packaging or by your healthcare provider.
- Clean the Area: Gently clean the affected area with mild soap and water or a cleansing wipe. Pat dry thoroughly to ensure the area is clean and free of debris.
- Prepare the Applicator: If using a product with an applicator, attach it securely to the tube and lubricate the tip with a small amount of the gel or cream.
- Apply Externally: For external relief, apply a thin layer of the product to the perianal area and rub in gently.
- Apply Internally: For internal application, insert the lubricated applicator tip gently into the anal opening (typically 1/2 to 1 inch). Squeeze the tube to release the medication as you withdraw the applicator.
- Wash Your Hands: Always wash your hands thoroughly with soap and water before and after application to prevent contamination.
Conclusion
In short, Glydo, a topical lidocaine gel, should not be used rectally. Its formulation and packaging are not suitable for internal application, and doing so could lead to risks such as increased systemic absorption and potential overdose. For the safe and effective treatment of anorectal pain, it is essential to use a lidocaine product specifically formulated for rectal use, such as those that come with a dedicated applicator and may be combined with hydrocortisone. Always follow the package instructions or your doctor's advice carefully. For more information, refer to authoritative sources like the National Institutes of Health or consult a healthcare professional.
If you have concerns or experience worsening symptoms like bleeding or severe irritation, stop use and contact your doctor immediately.
