Doxycycline Hyclate
Doxycycline hyclate is a broad-spectrum tetracycline antibiotic prescribed to treat or prevent a wide variety of bacterial infections. It’s the hyclate salt form of doxycycline — making it water-soluble and suitable for oral administration. It’s available as generic and under brand names like Vibramycin, Doryx, Targadox, and Acticlate and typically comes as tablets or capsules.
Doxycycline hyclate works by inhibiting bacterial protein synthesis, stopping bacteria from growing and multiplying. It’s prescribed for many conditions, including:
Respiratory infections (sinusitis, pneumonia)
Skin and soft-tissue infections (acne)
Urinary tract infections (UTIs)
Sexually transmitted infections (e.g., chlamydia)
Tick-borne illnesses (Lyme disease, Rocky Mountain spotted fever)
Malaria prophylaxis (prevention while traveling to endemic areas)
Other less common diseases (anthrax, plague, cholera)
Has anti-inflammatory properties used off-label (e.g., for acne or rosacea at lower doses).
Rapid “Doxy PEP” (post-exposure prophylaxis) is used by some clinicians to reduce certain bacterial STI risks after exposure.
Unlike antiviral drugs, doxycycline does not treat viral infections (e.g., colds, flu). Always take it only as prescribed.
