Bimectin Plus, 10/100 mg/ml Solution for Injection for Cattle — SPC Details
Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.
Linognathus vituli
Haematopinus eurysternus
Solenopotes capillatus.
The veterinary medicinal product may also be used as an aid in the control of biting lice
(Damalinia bovis)
and the mange mite Chorioptes bovis, but complete elimination may not occur.
Persistent activity
The veterinary medicinal product given at the recommended dosage of 1ml/50kg
bodyweight controls re- infection with Haemonchus placeiCooperia spp. and
Trichostrongylus axei acquired up to 14 days after treatment, Ostertagia ostertagi and
Oesophagostomum radiatum acquired up to 21 days after treatment and Dictyocaulus
viviparus acquired up to 28 days after treatment.
200 μg
1 ml per 50 kg bodyweight.
Method of administration
The veterinary medicinal product should be administered only by subcutaneous injection
under the loose skin in front of or behind the shoulder.
Divide doses in excess of 10 ml between different injection sites and use different sites to
those used for other parenteral medications.
A sterile 17 gauge ½ inch (15-20 mm) needle is recommended. Replace with a fresh
sterile needle after every 10-12 animals or sooner if the needle becomes soiled.
When the temperature of the product is below 5°C, difficulty in administration may be
encountered due to increased viscosity. Warming the product and injection equipment to
about 15°C will greatly increase the ease with which the product can be injected.
When using the 500 ml pack size use only automatic syringe equipment. For the 50 ml
pack size, use of a multidose syringe is recommended.
The timing of treatment should be based on epidemiological factors and should be
customised for each individual farm. A dosing program should be established by a
qualified professional person.
To ensure a correct dosage, body weight should be determined as accurately as possible;
accuracy of the dosing device should be checked.
If animals are to be treated collectively rather than individually, to avoid under- or over-
dosing, they should be grouped according to their bodyweight and dosed accordingly.

development of resistance and could ultimately result in ineffective therapy:
• Too frequent and repeated use of anthelmintics from the same class, over an
extended period of time.
AN: 02471/2024 & 02472/2024Page 3 of 7
• Underdosing, which may be due to underestimation of body weight,
misadministration of the product, or lack of calibration of the dosing device (if any).
Suspected clinical cases of resistance to anthelmintics should be further investigated using
appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the test(s)
strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to
another pharmacological class and having a different mode of action should be used.
Resistance to Ivermectin has been reported in Ostertagia ostertagi and species
in cattle within the EU. Therefore, the use of this product should be based on local
(regional, farm) epidemiological information about susceptibility of these helminth species
and recommendations on how to limit further selection for resistance to anthelmintics.
Special precautions for safe use in the target species:
This veterinary medicinal product does not contain any antimicrobial preservative. Swab
septum before removing each dose.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Do not smoke or eat whilst handling the veterinary medicinal product.
Wash hands after use.
Personal protective equipment consisting of gloves and glasses should be worn when
handling the veterinary medicinal product. Direct contact with the skin should be avoided.
Take care to avoid self-injection: the product may cause local irritation and/or pain at the
injection site. In case of accidental self-injection, seek medical advice immediately and
show the package leaflet or the label to the physician.
Special precautions for the protection of the environment:
The product is very toxic to aquatic organisms and dung insects. Treated cattle should not
have direct access to ponds, streams or ditches for 14 days after treatment. Long term
effects on dung insects caused by continuous or repeated use cannot be excluded.
Therefore, repeat treatments on a pasture within a season should only be given on the
advice of a veterinarian.
Milk: Do not use in cattle producing milk for human consumption.
Do not use in non-lactating dairy cows including pregnant heifers within 60 days of
calving.
