None.
Special precautions for use
As with other tetracyclines, caution should be exercised in treating horses under stress.
Exercise caution in animals with hepatic or renal impairment.
Not for intravenous administration in dogs or cats.
Operator warnings
Take care to avoid accidental injection.
In case of contact with eyes or skin, wash immediately with plenty of water as irritation may occur.
Wash hands after use.

Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for respective contact details.
Use during pregnancy or lactation
Pregnancy:
The use of tetracyclines during the period of tooth and bone development, including late pregnancy, may lead to tooth discolouration.
Interactions
It is not recommended to administer bacteriostatic and bactericidal antibiotics concurrently.
Amounts to be administered and administration route
The veterinary medicinal product can be administered at either a low dose rate for a 24 hour duration of activity or at a high dose rate for prolonged duration of activity.
24 hour dosage regime:
Large animals: Intramuscular use or intravenous use.
Small animals: Subcutaneous use or intramuscular use.
The recommended dosage rate is 3-10 mg/kg bodyweight (depending on age and species - see table) by intramuscular or intravenous injection in large animals and by subcutaneous or intramuscular injection in small animals.
The treatment may be repeated at 24 hour intervals up to 4 times (5 treatments in total).
Intravenous injections must be given slowly over a period of at least one minute.
Prolonged action dosage regime:
Intramuscular use.
10 or 20 mg/kg bodyweight depending on age and species (see table) by intramuscular injection only, repeated once after 48-60 hours if required.
This dosage regime is not advised for use in horses, dogs or cats.

Horse | 500 | 5 | 25 | Not recommended |
Foal | 100 | 10 | 10 | Not recommended |
Cow | 500 | 3 | 15 | 10 | 50 |

Prophylactic treatment of enzootic abortion in sheep: 20 mg/kg administered about day 95-100 of gestation. A further treatment may be given 2-3 weeks later.
Before administration, clean the area of the injection site and swab with spirit. Repeat doses should be administered at different sites, and the sites massaged well after injection.
