Doxycycline Injection, Tetracycline Antibiotic, Lyophilized Powder 10 mL x 10/Box (RX)

Doxycycline Injection is a broad-spectrum, semi-synthetic antibiotic belonging to the tetracycline class. The product is supplied as a lyophilized powder that is reconstituted for intravenous (IV) infusion. Manufactured by Slate Run Pharmaceuticals, this injectable form is particularly useful when oral therapy is not feasible (e.g., patients unable to swallow or with GI tract absorption issues). Indications Doxycycline injection is indicated for: Severe bacterial infections susceptible to doxycycline, especially when oral administration is not appropriate. Respiratory tract infections: Pneumonia, bronchitis caused by susceptible organisms. Intra-abdominal infections Skin and soft tissue infections Urinary tract infections (UTIs) Rickettsial infections: Rocky Mountain spotted fever, typhus Sexually transmitted infections (STIs): Chlamydia trachomatis, syphilis (in penicillin-allergic patients), pelvic inflammatory disease Anthrax (including inhalational post-exposure), plague, tularemia, and brucellosis as part of bioterrorism preparedness or rare exposure Benefits Broad-spectrum activity: Effective against a wide range of Gram-positive and Gram-negative bacteria, including atypical organisms (Chlamydia, Mycoplasma, Rickettsia). IV formulation: Critical for patients unable to take oral doxycycline (e.g., vomiting, unconsciousness, NPO status). Good tissue penetration: Useful for deep-seated or disseminated infections. Alternative therapy: Beneficial for those allergic to penicillin and cephalosporins. How to Use Preparation and Administration: Reconstitution: The lyophilized powder is reconstituted with the provided diluent (usually sterile water or compatible IV fluid) according to manufacturer’s instructions. Dilution: The reconstituted solution is further diluted for IV infusion. Administration: Administer the diluted solution by slow IV infusion (never as a rapid IV bolus), typically over 1-4 hours depending on the total dose. Dosing: Dosage varies by indication, patient age, and renal/hepatic function. Adults typically receive 100 mg every 12 hours, but always follow specific dosing recommendations by your healthcare provider or local protocols.

Side Effects Common Side Effects: GI upset (nausea, vomiting, diarrhea) Injection site reactions (pain, phlebitis) Skin photosensitivity Headache Serious/Uncommon Side Effects: Severe allergic reactions (anaphylaxis, rash) Hepatotoxicity (liver dysfunction) Blood disorders (eosinophilia, anemia, thrombocytopenia) Intracranial hypertension (persistent headache, blurred vision) Superinfection (candida or Clostridioides difficile-associated diarrhea) Warnings & Precautions Hypersensitivity: Contraindicated in patients with known hypersensitivity to tetracyclines. Pregnancy/Breastfeeding: Use with caution. Tetracyclines can cause permanent tooth discoloration and inhibit bone growth in the fetus/infants.
