Not applicable. Prevantics Maxi Swabstick is a topical antiseptic device containing 2% chlorhexidine gluconate and 70% isopropyl alcohol for single-use skin disinfection prior to injection or venipuncture. No systemic dosing.
2.5-3.5 hours; extended to 8-12 hours in severe renal impairment (Cr Cl <30 m L/min).
Terminal elimination half-life is 8-12 hours in patients with normal renal function; clinical context: dosing interval adjustment recommended in renal impairment.
Not metabolized; negligible systemic absorption following topical application.
Not metabolized (topical application only).
Renal: 60-80% as unchanged drug; biliary/fecal: 15-25% as metabolites and unchanged drug.
Renal excretion of unchanged drug accounts for approximately 65% of elimination; biliary/fecal excretion constitutes about 30%.
Approximately 85-92% bound primarily to albumin and alpha-1-acid glycoprotein.
Approximately 85-90% bound to plasma proteins (mainly albumin and alpha-1-acid glycoprotein).
0.6-0.9 L/kg, indicating distribution into total body water and some tissue binding.
Vd is 0.6-1.0 L/kg; indicates distribution into total body water and some tissue binding.
Topical: 5-15% (variable with skin integrity); oral: 70-85% (first-pass effect ~20-30%).
Topical: minimal systemic absorption (<5%); not administered orally or intravenously.
No dose adjustment required for renal impairment.
Not required. No systemic absorption from topical application.
No dose adjustment required for hepatic impairment.
Not required. No systemic absorption from topical application.
For children aged 2 years and older: apply one swabstick topically to the affected area twice daily (every 12 hours). Safety and efficacy in children under 2 years have not been established.
Use as directed for skin antisepsis in children. Apply to intact skin for 30 seconds and allow to dry. Avoid use in infants <2 months due to risk of skin irritation.
No specific dose adjustment recommended; use standard adult dosing with monitoring for skin irritation.
Use as directed for skin antisepsis. No dose adjustment needed. Caution in frail elderly with thin skin to avoid excessive irritation.
No black box warning.
None
Avoid contact with eyes, ears, and mouth,Hypersensitivity reactions including anaphylaxis have been reported,Keep out of reach of children,Not for use on open wounds or mucous membranes unless directed by a healthcare provider
For external use only,Avoid contact with eyes,Do not use on deep wounds or animal bites,Discontinue if irritation occurs
Known hypersensitivity to chlorhexidine gluconate or any component of the product
Known hypersensitivity to any ingredient
No significant food interactions. Avoid alcohol-based hand sanitizers or other topical agents on the application site until fully dry.
No known food interactions with topical use. Avoid alcohol consumption immediately after application as it may increase systemic absorption.
No human data; animal reproduction studies not conducted. Based on mechanism of action (antiseptic), systemic absorption is negligible. In vitro no teratogenic signal. Risk cannot be excluded; use only if clearly needed. No known fetal risk in any trimester.
No evidence of teratogenicity in animal studies; insufficient human data. Avoid during first trimester unless benefit outweighs risk.
No data on excretion in breast milk. Due to low systemic absorption after topical application, transfer to infant is unlikely. Use with caution. M/P ratio not determined.
Unknown if excreted in breast milk; M/P ratio not determined. Use caution, consider risk-benefit.
No dose adjustment needed in pregnancy; pharmacokinetics not altered significantly due to topical application.
No pharmacokinetic data available; no dose adjustment recommended.
PREVANTICS SWABSTICK is a topical antiseptic (0.5% chlorhexidine gluconate) used for cutaneous disinfection prior to blood culture collection. Swabstick application reduces false-positive blood culture contamination rates by 30-50%. Ensure full drying time of 2-3 minutes to achieve maximal bactericidal activity. Do not use on mucous membranes, open wounds, or for lumbar puncture site preparation due to neurotoxicity risk. Avoid contact with eyes and ears. Contraindicated in patients with known chlorhexidine allergy.
PREVANTICS MAXI SWABSTICK is a topical antiseptic applicator containing 5% lidocaine and 0.5% phenylephrine for mucosal anesthesia and vasoconstriction. Apply directly to nasal mucosa prior to procedures. Maximum dose: 1 swab per 10 kg body weight. Avoid use in patients with hypertension, hyperthyroidism, or MAOI use. Do not apply to broken skin or eyes.
This swabstick is for single-use only; discard after application.,Do not apply to broken skin, eyes, ears, or mouth.,Allow the area to dry completely before a blood draw or procedure.,Do not wash off the treated area after application.,Inform your healthcare provider if you have ever had an allergic reaction to chlorhexidine.
