Prevduo (doxycycline hyclate and omadacycline) is a combination of two tetracycline antibiotics. Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-t RNA from binding to the m RNA-ribosome complex. Omadacycline, a aminomethylcycline, also binds to the 30S subunit but overcomes common tetracycline resistance mechanisms (e.g., efflux pumps, ribosomal protection proteins).
Physical removal of microorganisms and debris through mechanical friction combined with the antiseptic action of 1% betadine (povidone-iodine), which oxidizes proteins and DNA of microbial cells, causing cell death.
Acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible pathogens,Community-acquired bacterial pneumonia (CABP),Uncomplicated skin and soft tissue infections (off-label),Acne vulgaris (off-label)
Preoperative surgical hand antisepsis,Healthcare personnel hand washing
Adults: 1 tablet (500 mg sulfamethoxazole/80 mg trimethoprim) orally every 12 hours for 14 days.
Scrub for 2-3 minutes using spongebrush with 4% chlorhexidine gluconate or 7.5% povidone-iodine, then rinse. Apply to surgical site; no systemic dosing.
Terminal half-life 9-12 hours (prolonged in renal impairment, clinical monitoring recommended)
Not applicable; chlorhexidine gluconate exhibits prolonged skin binding without systemic absorption. Terminal half-life in plasma is not measurable due to negligible systemic levels.
Doxycycline is partially metabolized in the liver via glucuronidation and other pathways; excreted in feces and urine. Omadacycline is not significantly metabolized; primarily eliminated unchanged in feces and urine.
Not applicable; topical antiseptic with no systemic absorption.
Renal: 70% unchanged; fecal: 20% (biliary); 10% metabolized
Not systemically absorbed; active ingredient (chlorhexidine gluconate) is not excreted via renal or hepatic routes. Eliminated primarily through desquamation of skin cells and washing off. No renal or biliary excretion occurs.
85-90% bound to albumin and alpha-1-acid glycoprotein
Not applicable; chlorhexidine is not systemically absorbed. At local skin site, it binds to proteins in the stratum corneum, but percentage is not defined clinically.
1.5 L/kg (extensive distribution; suggests high tissue penetration)
Not applicable; chlorhexidine is not absorbed into systemic circulation. Volume of distribution is not defined for topical application.
Oral: 60-70% (first-pass metabolism; food reduces absorption by 20%)
Negligible (<0.1%) via intact skin; systemic absorption is minimal. Bioavailability via oral or mucous membrane routes is not relevant for this product.
Cr Cl 15-30 m L/min: 50% of standard dose every 12 hours. Cr Cl <15 m L/min: not recommended.
No dosage adjustment required for topical use.
Child-Pugh Class A: no adjustment needed. Child-Pugh Class B or C: contraindicated.
No dosage adjustment required for topical use.
Children: 8 mg/kg/day trimethoprim and 40 mg/kg/day sulfamethoxazole divided every 12 hours. Maximum duration 14 days.
Use as directed; scrub for 2-3 minutes with sponge, avoiding prolonged contact. Not recommended for infants <2 months due to skin sensitivity.
Monitor renal function; reduce dose if Cr Cl <30 m L/min; avoid in elderly with folate deficiency.
Use as directed; monitor skin integrity due to thinner skin. No dose adjustment needed.
No FDA black box warnings are listed for Prevduo.
None.
May cause tooth discoloration and enamel hypoplasia if used during tooth development (children <8 years),May cause photosensitivity; avoid excessive sunlight or UV exposure,Use caution in patients with hepatic impairment,May result in overgrowth of non-susceptible organisms including Clostridioides difficile,Potential for decreased efficacy with concomitant use of antacids, iron, or multivitamins,May cause dizziness or lightheadedness; caution when driving or operating machinery
For external use only; avoid contact with eyes, ears, and mouth.,May cause skin irritation or allergic reactions in sensitive individuals.,Do not use on compromised skin or open wounds.,Discontinue if irritation or rash develops.
Hypersensitivity to doxycycline, omadacycline, or any tetracycline,Pregnancy (may cause fetal harm based on animal data),Lactation (potential for serious adverse reactions in nursing infants)
Known hypersensitivity to iodine or other components of the product
Avoid grapefruit and grapefruit juice during treatment. No significant food interactions otherwise.
None known; product is for topical use only and not ingested.
Pregnancy Category X. First trimester: high risk of skeletal and cardiac malformations (neural tube defects, cleft palate). Second and third trimesters: oligohydramnios, renal agenesis, pulmonary hypoplasia, intracranial hemorrhage, and fetal death.
Scrubteam Surgical Spongebrush contains chlorhexidine gluconate. No teratogenic risk in humans; systemic absorption negligible. No known fetal risk across trimesters due to minimal absorption.
Contraindicated due to risk of neonatal hypotension, nephrotoxicity, and cardiac arrest. M/P ratio not determined; likely excreted in breast milk.
Compatible with breastfeeding. Chlorhexidine has negligible systemic absorption; M/P ratio not applicable.
No dose adjustments possible due to teratogenicity; drug is contraindicated throughout pregnancy. If inadvertently used, immediate discontinuation and specialist consultation required.
No dosing adjustment needed. Pharmacokinetics unchanged during pregnancy due to topical use and minimal absorption.
PREVDUO (budesonide/glycopyrrolate/formoterol fumarate) is a fixed-dose triple therapy for COPD. Administer as two inhalations twice daily. No rescue use. Titrate to lowest effective dose. Monitor for pneumonia, oral candidiasis, and hypercortisolism. Use with caution in patients with severe hepatic impairment. Assess cardiovascular risk due to formoterol.
Use 2% chlorhexidine gluconate (CHG) scrub for surgical site antisepsis; avoid alcohol-only preparations due to flammability and reduced efficacy against spores. Allow CHG to dry for at least 3 minutes before draping. Do not use on mucous membranes, open wounds, or in children under 2 months. For allergic patients, substitute with povidone-iodine.
Use exactly as prescribed; do not use for sudden symptoms.,Rinse mouth with water after each dose to prevent thrush.,Avoid exceeding two inhalations twice daily.,Report worsening symptoms or need for increased rescue inhaler use.,Notify healthcare provider of any vision changes, signs of infection, or adrenal insufficiency.
Do not use on face, eyes, ears, mouth, or genital area.,Avoid contact with open wounds or burns.,Rinse thoroughly after use to prevent skin irritation.,Inform your surgeon if you have allergic reactions to antiseptics.,Do not use if you have a history of sensitivity to chlorhexidine or iodine.
