Type / Class: Broad-spectrum antibiotic (tetracycline class)
Usually sold as 10 tablets per pack in pet / veterinary supply outlets.
Active Ingredient & Mechanism
The active drug is Doxycycline (a tetracycline antibiotic) (Docmycin is a branded formulation).
Mechanism: Doxycycline inhibits bacterial protein synthesis (binding to the 30S ribosomal subunit), thereby preventing bacterial growth and replication.
Indications / Uses
Docmycin (Doxycycline) is used for a variety of bacterial infections in animals, including:
Respiratory tract infections (e.g. pneumonia)
Skin, urinary tract, and genital infections
Tick-borne diseases, Lyme’s disease, and similar systemic infections (in veterinary use)
It may also be used as part of treatment regimens for broader infections in animals (off-label)
Dosage & Administration
The strength in question is often 300 mg per tablet for some formulations.
Dosage (mg per kg of body weight) depends heavily on the species, severity of infection, and veterinary guidance.
Administration is oral (tablet form).
It is recommended to give with food or a little water to reduce stomach irritation and to ensure it passes into the stomach (avoid the tablet lodging in the esophagus).
Precautions, Contraindications & Side Effects
Precautions & Contraindications
Do not use in animals allergic to doxycycline or other tetracycline antibiotics.
Use cautiously (or avoid) in young growing animals (because tetracyclines can affect bone growth and discolor teeth).
Use with caution in animals with liver disease or renal impairment.
Avoid use during pregnancy or lactation unless the benefit outweighs the risk.
Possible esophageal irritation if pills get stuck (particularly in small animals)
Increased sensitivity to sunlight (photosensitivity)
More serious or rare:
Liver toxicity or liver enzyme elevation
Jaundice
Severe allergic reactions
If you see symptoms like vomiting blood, yellowing of gums/skin, severe lethargy, or difficulty swallowing, stop the drug and consult a vet.
Drug Interactions & Absorption Issues
Avoid giving concurrently (or within a window) with calcium, iron, antacids, dairy products, multivitamins, etc., because they may bind doxycycline and reduce absorption.
Other antibiotics, anticoagulants, or drugs affecting liver metabolism may interact.
Storage & HandlingDOC
Store at room temperature in a dry place, protected from moisture and light.
Keep out of reach of children and animals.
Do not use beyond the expiry date or if tablet is damaged.
