Hypersensitivity to omadacycline, tetracycline-class antibacterial drugs, or any component of the formulation.
Concerns related to adverse effects:
• Anaphylactic/Hypersensitivity reactions: Hypersensitivity reactions have been reported; life-threatening hypersensitivity (anaphylactic) reactions have been reported with other tetracyclines. Discontinue if an allergic reaction occurs. Avoid use in patients with known hypersensitivity to tetracyclines.
• Antianabolic effects: May be associated with antianabolic effects observed with the tetracycline class (including increased BUN, azotemia, acidosis, and hyperphosphatemia); discontinue use if suspected.
• Fixed drug eruption: May be associated with fixed drug eruption due to structural similarities with tetracyclines; discontinue use if suspected.
• Hepatotoxicity: May be associated with abnormal liver function tests due to structural similarities with tetracyclines; discontinue use when suspected.
• Pancreatitis: May be associated with pancreatitis due to structural similarities with tetracyclines; discontinue use if suspected.
• Photosensitivity: May be associated with photosensitivity due to structural similarities with tetracyclines. Use skin protection and avoid prolonged exposure to sunlight and ultraviolet light. Discontinue use if skin erythema occurs.
• Pseudotumor cerebri: May be associated with pseudotumor cerebri due to structural similarities with tetracyclines; discontinue use if suspected.
• Superinfection: Use may result in fungal or bacterial superinfection, including Clostridioides difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
Disease-related concerns:
• Community-acquired bacterial pneumonia: Mortality rate was higher in patients treated with omadacycline for community-acquired bacterial pneumonia (CABP) compared to patients treated with moxifloxacin. All deaths occurred in patients >65 years of age with multiple comorbidities.
Special populations:
• Older adult: Numerically lower clinical success rates at the early clinical response timepoint were observed in CABP patients ≥65 years of age compared to patients <65 years of age. In addition, all deaths in the CABP trial occurred in patients >65 years of age.
• Pediatric: May cause reversible inhibition of bone growth when used during the second and third trimesters of pregnancy, infancy, and childhood ≤8 years of age. May cause tooth enamel hypoplasia or permanent tooth discoloration (more common with long-term use, but observed with repeated, short courses) when used during tooth development (last half of pregnancy, infancy, and childhood ≤8 years of age). Avoid use in children <8 years of age.

Oral omadacycline serum levels may be decreased if taken with high-fat meal or dairy. Management: Administer oral omadacycline after fasting for ≥4 hours, avoid food and drink (except water) for 2 hours after administration, and avoid dairy products for 4 hours after administration.
Due to the potential for adverse pregnancy outcomes, the manufacturer recommends effective contraception for patients who could become pregnant during omadacycline therapy.
Tetracyclines accumulate in developing teeth and long tubular bones. Permanent discoloration of teeth (yellow, gray, brown) can occur following in utero exposure and is more likely to occur in the second or third trimesters and following long-term or repeated exposure. Reversible inhibition of bone growth may occur following maternal use of tetracyclines in the second and third trimesters.
Omadacycline is not one of the recommended antibiotics for the treatment of plague (Y. pestis) in pregnant patients (CDC [Nelson 2021]).
It is not known if omadacycline is present in breast milk.
As a class, tetracyclines have generally been avoided in breastfeeding patients due to concerns that they may cause adverse events in the breastfeeding infant, including tooth discoloration and inhibition of bone growth. Due to the potential for adverse events, the manufacturer does not recommend breastfeeding during therapy or for 4 days after the last omadacycline dose.
Tablets: Take with water on an empty stomach (after ≥4 hours of fasting); avoid food and drink (except water) for 2 hours after taking and avoid dairy products for 4 hours after taking.
Periodic renal and hepatic function tests; clinical response in patients with community-acquired bacterial pneumonia, particularly those with higher mortality risk (eg, patients ≥65 years of age).
Omadacycline inhibits protein synthesis by binding with the 30S ribosomal subunit of susceptible bacteria.
Absorption: Food decreases rate and extent of absorption
Distribution: IV: Vdss: 190 L; tissue concentrations exceed plasma concentrations in alveolar cells and epithelial lining fluid
Protein binding: 20%; not concentration dependent

Bioavailability: Oral: 34.5% following a single 300 mg dose
Half-life elimination: IV: ~16 hours; Oral: 13.45 to 16.83 hours

Anti-infective considerations:
Parameters associated with efficacy: Limited data available: AUC24/minimum inhibitory concentration (MIC): Goal AUC24/MIC targets are highly variable and may depend on specific pathogen and inoculum, site of infection, and other host factors (Lepak 2017; Lepak 2020; Rodvold 2019; VanScoy 2020).
Organism specific:
S. pneumoniae: Goal: AUC24/MIC not well defined; reported AUC24/MIC values are highly variable, ranging from 6.06 to 179.98 (1-log kill) (Lepak 2017).
S. aureus: Goal: AUC24/MIC <1.06 to 16.97 (1-log kill) (Lepak 2020).
Mycobacterium kansasii: Goal: AUC24/MIC: 1.96 (50% of the maximal effect; EC50), AUC24/MIC: 3.05 (80% of the maximal effect; EC80) (Singh 2022).
