ii) Special precautions to be taken by the person administering the veterinary
medicinal product to animals

Cephalosporins may cause sensitization (allergy) following injection, inhalation, ingestion or
skin contact. Sensitivity to penicillins may lead to cross sensitivity to cephalosporin and vice
versa. Allergic reactions to these substances may occasionally be serious.

1. Do not handle this product if you know you are sensitized or if you have been advised not to
work with such preparations.
2. Handle this product with great care to avoid exposure, taking all recommended
precautions. Wash hands after use.
3. If you develop symptoms following exposure such as skin rash you should seek medical
advice and show the doctor this warning. Swellings of the face, lips or eyes or difficulty
breathing are more serious symptoms and require urgent medical attention.

In the event of accidental ingestion, particularly by a child, seek medial attention and show the
doctor the leaflet

4.6   Adverse reactions (frequency and seriousness)

Vomiting and diarrhoea have been observed in dogs. In rare cases hypersensitivity can occur.

4.7    Use during pregnancy, lactation or lay

Do not use in pregnant or lactating bitches.

4.8   Interaction with other medicinal products and other forms of interaction

In order to ensure efficacy, the product should not be used in combination with bacteriostatic
Concurrent use of first generation cephalosporins with aminoglycoside antibiotics or some
diuretics such as furosemide can enhance nephrotoxicity risks

4.9    Amounts to be administered and administration route
For oral administration.

15 mg cefalexin per kg bodyweight twice daily (equivalent to 30 mg per kg bodyweight per
day) for duration of:
- 14 days in cases of urinary tract infection
- At least 15 days in cases of superficial infectious dermatitis
- At least 28 days in cases of deep infectious dermatitis

In severe or acute conditions the dose may be safely doubled to 30 mg/kg twice daily. To
allow for accuracy of dosing, tablets can be halved or quartered.

To ensure a correct dosage bodyweight should be determined as accurately as possible to
avoid underdosing.

Therios tablets are well accepted by dogs but may be crushed or added to a small quantity of
food immediately prior to feeding if necessary
