Definition:
LOX 0.02 is a low-concentration local anesthetic solution typically containing Lidocaine Hydrochloride 0.02%, designed for minimally invasive procedures requiring subtle numbing.
INTRODUCTION
LOX 0.02 is formulated for:
-
Superficial numbing (e.g., fine-needle procedures, microneedling).
-
Pediatric/delicate applications where standard doses may be excessive.
-
Ophthalmic/dental mucosal use (low-irritation formula).
Unlike higher-dose anesthetics, it minimizes tissue distortion while providing adequate analgesia.
DESCRIPTION
Composition:
-
Lidocaine HCl 0.02%Â (ultra-low dose).
-
Preservatives: Chlorhexidine or EDTA in some formulations.
-
pH-adjusted (~6.5–7.0) to reduce stinging.
Key Properties:
-
Onset: 2–5 minutes (mucosa); 5–10 minutes (skin).
-
Duration: 15–30 minutes (ideal for brief procedures).
-
No vasoconstrictors – Reduces ischemic risk in sensitive areas.
USES
-
Aesthetic Medicine:
-
Botox/filler injections (minimizes post-procedure swelling).
-
Fractional laser treatments.
-
-
Diagnostics:
-
Capillary blood sampling (neonatal heel sticks).
-
Intradermal allergy testing.
-
-
Ophthalmic:
-
Corneal foreign body removal (preservative-free variants).
-
SIDE EFFECTS
Expected/Minor:
-
Transient warmth/tingling at application site.
-
Mild conjunctival redness (if ocular use).
Risks (With Overuse):
-
Allergic contact dermatitis (rare with this concentration).
-
Corneal abrasion (if improperly applied to eyes).
ADVANTAGES OVER STANDARD FORMULATIONS
Feature | LOX 0.02 | Traditional 2% Lidocaine |
---|---|---|
Tissue Distortion | Minimal | Significant (due to volume) |
Procedure Suitability | Micro-injections | Major nerve blocks |
Safety Margin | Very high | Requires careful dosing |
STORAGE
-
Room temperature (15–30°C).
-
Protect from light (amber vials for injectable forms).
-
Single-use vials: Discard within 4 hours of opening.
CONCLUSION
LOX 0.02 fills a niche for precision procedures where tissue integrity matters. Its safety profile makes it ideal for:
-
Pediatric care
-
Aesthetic dermatology
-
Mucosal applications
Limitations: Not for deep analgesia; requires supplemental anesthesia for longer procedures.
