Paying less for Diclazuril

  1. 1

    Ask your vet for a written prescription

    They must provide one on request. Under the CMA Order the fee is capped at £21 from 2027.

  2. 2

    Fill it at a registered online retailer

    The CMA found online pharmacies 50–60% cheaper than practice dispensing on common medicines — typically £200–£300 a year.

Prescription required

Your vet must provide a written prescription on request. You can then purchase from any licensed online retailer.

Clinical information

Dicla-cocci 2.5 mg/ml Oral Suspension for Cattle and Sheep — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

To aid in the control of coccidiosis in calves caused by Eimeria bovis and
Oral suspension to be administered at a dosage of 1 mg diclazuril per kg body weight
i.e. 1 mL per 2.5 kg body weight in a single oral administration.
To ensure a correct dosage, body weight should be determined as accurately as
possible.
AN: 01331/2025 & 01375/2025
Underdosing could result in ineffective use and may favour resistance development.
Method of administration:
Shake vigorously for 1 minute by repeatedly turning the bottle upside down by wrist
action.
For the 5 L and 2.5 L back-pack bottles, use a drenching gun. Connect the drenching
gun and draw-off tubing to the back-pack bottle as follows:
•
•
•
the spigot cap.
•
•
proper use and maintenance of the drenching gun and draw-off tubing.
•
For the 1 L and 250 mL bottles, to ensure a correct dosage, the use of either a
syringe or an appropriate device for oral administration is necessary and the
veterinary medicinal product should be administered directly in the mouth of the
animal.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipient(s).
Cattle (calves) and sheep (lambs):
Very rare
(<1 animal / 10 000 animals
treated, including isolated
reports):
Gastrointestinal signs (e.g. Diarrhea
1,2
);
Lethargy, Recumbency;
Agitation;
Neurological signs (e.g. Paresis)
: with possible presence of blood
: even though oocyst excretion is reduced to a very low level.
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
contact details.
Calves:
In certain cases, only a transient reduction of oocyst shedding may be achieved.
If there is no recent and confirmed history of clinical coccidiosis, the presence of the
disease in the flock or herd should be confirmed by faecal sampling prior to
treatment.
The preferred timing of treatment is directed by the known epidemiology of Eimeria
spp. with treatment being most effective during the pre-patent phase of the infection
before clinical signs occur.
Coccidiosis is an indicator of insufficient hygiene in the flock/pen. It is recommended
to improve hygiene and to treat all calves in a pen and all lambs in a group. This will
contribute to reduce the infection pressure and assure a better epidemiological
control of the coccidiosis infection.
Repeated use for an extended period, particularly when using the same class of
substances, increases the risk of resistance development. The decision to use the
product should be based on confirmation of the coccidian species and burden, or of
the risk of infection based on its epidemiological features, for each herd/flock.
Unnecessary use of antiprotozoals or use deviating from the instructions given in the
SPC may increase the resistance selection pressure and lead to reduced efficacy.
Cross-resistance between toltrazuril and diclazuril is possible and should be
investigated. Use of diclazuril should be carefully considered when susceptibility
testing has shown resistance to triazine-derivates because its effectiveness may be
reduced.
It is recommended to further investigate cases of suspected resistance, using an
appropriate diagnostic method (e.g. faecal oocyst count reduction test). Confirmed
resistance should be reported to the marketing authorisation holder or to the competent
authorities. If resistance is present, it should be considered to use an antiprotozoal
from another class/with a different mechanism of action.
Therapy should be based on epidemiological information and knowledge of
susceptibility of the target pathogens at farm level, or at local/regional level.
Use of the product should be in accordance with official, national and regional
antimicrobial policies.
To alter the course of an established clinical coccidial infection, in individual animals
already showing signs of diarrhoea, additional supportive therapy is required.
AN: 01331/2025 & 01375/2025

Special precautions for safe use in the target species:
