E-Z SCRUB 201
Clinical safety rating: caution
Comprehensive clinical and safety monograph for E-Z SCRUB 201 (E-Z SCRUB 201).
E-Z SCRUB 201 is a topical antiseptic containing chlorhexidine gluconate (CHG), which disrupts microbial cell membranes via adsorption to cell wall components, leading to leakage of cytoplasmic contents and cell death. It has broad-spectrum activity against gram-positive and gram-negative bacteria, fungi, and some viruses.
| Metabolism | Chlorhexidine gluconate is minimally absorbed through intact skin. Systemic absorption is negligible; therefore, metabolism is not clinically significant. If absorbed, it is excreted unchanged in urine. |
| Excretion | E-Z SCRUB 201 is a topical antiseptic containing 2% chlorhexidine gluconate. Following topical application, systemic absorption is negligible (<0.1%). The small absorbed fraction is primarily excreted renally (30%) and fecally (70%), with minimal biliary elimination. Most of the dose remains on the skin and is removed by washing. |
| Half-life | Not applicable for topical use due to negligible systemic absorption. In the event of accidental intravenous administration, the terminal elimination half-life of chlorhexidine is approximately 1-2 hours. |
| Protein binding | Systemic chlorhexidine is highly protein-bound (>90%) primarily to albumin. However, for E-Z SCRUB 201 used topically, protein binding is clinically irrelevant due to minimal absorption. |
| Volume of Distribution | For topically applied chlorhexidine, Vd is not applicable. Following IV administration in studies, Vd is approximately 1-2 L/kg, indicating extensive tissue distribution, but this does not apply to E-Z SCRUB 201. |
| Bioavailability | Topical: Negligible systemic bioavailability (<0.1%) due to minimal percutaneous absorption. Oral ingestion (accidental) results in poor bioavailability of about 1-2% due to first-pass metabolism. |
| Onset of Action | Topical: Immediate upon application; antimicrobial effect begins within 15-30 seconds as chlorhexidine binds to skin proteins. |
| Duration of Action | Topical: Sustained antimicrobial activity for up to 6 hours after a single application due to residual binding to stratum corneum; clinical efficacy supports surgical site preparation with duration covering the surgical procedure. |
E-Z SCRUB 201 is not a systemic drug; it is a topical antiseptic surgical scrub. Standard application involves 5 mL applied to wet hands and forearms, scrubbed for 3 minutes, then rinsed. Repeat for second 3-minute scrub.
| Dosage form | SPONGE |
| Renal impairment | No adjustment required as topical application results in negligible systemic absorption. |
| Liver impairment | No adjustment required; no hepatic metabolism involved. |
| Pediatric use | Use with caution; follow institutional protocols. Typically, a smaller volume (2-3 mL) applied for 2-3 minutes per scrub, based on age and weight. |
| Geriatric use | Use standard adult dose; consider fragile skin, but no dose modification needed. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |
| 3rd trimester | Consult provider |
Clinical note
Comprehensive clinical and safety monograph for E-Z SCRUB 201 (E-Z SCRUB 201).
| Breastfeeding | Minimal systemic absorption suggests negligible excretion into breast milk. M/P ratio not applicable due to topical use. Considered compatible with breastfeeding. |
| Teratogenic Risk | E-Z SCRUB 201 (chlorhexidine gluconate 4% with isopropyl alcohol 70%) is not systemically absorbed. No fetal risk is expected at any trimester. |
| Fetal Monitoring | No specific monitoring required due to lack of systemic absorption. |
■ FDA Black Box Warning
None
| Serious Effects |
["Known hypersensitivity to chlorhexidine gluconate or any ingredient in the formulation","Prior history of allergic reaction to chlorhexidine-containing products"]
| Precautions | ["Avoid contact with eyes, ears, and mouth","Do not use on meninges, brain tissue, or middle ear","Hypersensitivity reactions including anaphylaxis may occur","Prolonged contact with mucous membranes may cause irritation","Keep out of reach of children"] |
| Food/Dietary | No known food interactions. However, limited iodine intake may affect thyroid function; patients with thyroid disorders should maintain consistent iodine dietary intake. |

| Fertility Effects | No known effects on fertility from topical use. |
| Clinical Pearls |
| E-Z SCRUB 201 is a povidone-iodine surgical scrub. For maximum antimicrobial efficacy, apply for at least 2 minutes on wet skin. Avoid use in patients with thyroid disorders (especially hyperthyroidism) or iodine allergy. Do not use with silicone-containing dressings as iodine can degrade silicone. |
| Patient Advice | Do not use if you are allergic to iodine or shellfish. · Avoid contact with eyes, ears, and mouth; if contact occurs, rinse thoroughly with water. · For external use only; do not ingest. · Allow to dry completely before covering with sterile dressing to prevent skin irritation. · Inform your doctor if you have a thyroid condition or are pregnant/breastfeeding. |
