Application for cattle and horses is done preferably by deep intramuscular injection. When high doses of Berenil® R.T.U. are applied, it is best to apply the injections at different locations in order to avoid local pain.

Dogs: The recommended dosage is 0,1 ml per 2 kg body mass injected intramuscularly or subcutaneously. This dosage must not be exceeded. In this case inject only once. If the animal does not recover after one injection consult a veterinarian for further treatment.

Suggested uses of Berenil® R.T.U. in the prevention of Redwater:

  1. Protection of susceptible cattle being moved through a Redwater area: Inject Berenil® R.T.U. at recommended dosage to prevent Asiatic (European) Redwater for 2 weeks and African Redwater for 4 weeks.
  2. Controlling a Redwater outbreak in a cattle herd: Inject all cattle with Berenil® R.T.U. at recommended dosage. This should stop further cases of Redwater within 24 hours and cure affected animals if not terminally ill.
  3. Protection of stud animals at shows where the immune state of the animals to Redwater is uncertain: Use Berenil® R.T.U. at recommended dosage to prevent Redwater for the periods as mentioned in number 1 above. Keeping the animals tick free reduces chances of Redwater transmission following these periods.
  4. Routine treatment of cattle arriving at feedlots: The use of Berenil® R.T.U. in this case renders protection as explained in number 1 above. Cure of animals already affected by Redwater may be expected, provided they are not terminally ill. The control of ticks on cattle at time of arrival should be coupled to the process.
  5. Vaccine warning: Should a bovine be treated for Redwater with Berenil® R.T.U., the animal should not be vaccinated against Asiatic Redwater for 1 month, and against African Redwater for 2 months after treatment. If Berenil® R.T.U. has been used to suppress a Redwater vaccine reaction, re-vaccination of the treated animals is necessary. If immunity to Asiatic Redwater is required, re-vaccination after 1 month is recommended. If immunity to African Redwater is required, re-vaccination after 2 months is recommended.
