Dosage & Administration

Levacide Pour-On is indicated for external pour-on transcutaneous administration to cattle.

The recommended dose rate is 10 mg levamisole per kg bodyweight, equivalent to 2.5 ml per 50 kg bodyweight.

The bodyweight of animals should be assessed as accurately as possible before calculating the dosage.

Bodyweight Dose
Up to 50 kg (1 cwt) 2.5 ml
51-100 kg (1-2 cwt) 5 ml
101-150 kg (2-3 cwt) 7.5 ml
151-200 kg (3-4 cwt) 10 ml
201-250 kg (4-5 cwt) 12.5 ml
251-300 kg (5-6 cwt) 15 ml
301-350 kg (6-7 cwt) 17.5 ml

Above 350 kg give a further 2.5 ml for each additional 50 kg bodyweight.

For external administration only: Pour on from the calibrated dispenser or using a standard dosing gun. Apply along the flattest part of the backline at the rate of 10 mg levamisole/kg bodyweight, equivalent to 2.5 ml per 50 kg bodyweight.

Dosing schedule: Dose all young cattle in early summer and if possible move onto clean pasture. Seek veterinary advice on subsequent retreatment.

Treatment of lungworm infection: Cattle should be dosed on the first signs of lungworm infestation; (rapid breathing or coughing). Seek veterinary advice on subsequent retreatment.

Shake well before use.

Equipment should be thoroughly cleaned before and after dosing.

For the 500 ml twin neck dispenser, simply squeeze the bottle to allow the appropriate amount of liquid into the calibrated dispenser. The 2.5 L Jerry-can should be used in conjunction with a standard dosing gun.

Withdrawal Period

Animals must not be slaughtered for human consumption during treatment. Cattle may be slaughtered for human consumption only after 28 days from the last treatment. Do not use in animals producing milk for human consumption.

Contraindictions, Warnings etc

For external use only.

Do not treat animals when wet, and where possible, prevent treated animals from being exposed to rain for one hour post treatment.

Levacide Pour-On is safe for use in cattle at the recommended dosage. In cases of overdosage, hyperaesthesia, tremor and occasionally diarrhoea may occur.

Cattle must not be treated within a period of 14 days before or after treatment with organophosphorus compounds.

Do not exceed the stated dose.

The bodyweight of animals should be assessed as accurately as possible before calculating the dose. As with other anthelmintics, veterinary advice should be sought:

(a) on appropriate dosing programmes and stock management to achieve adequate parasite control, and to reduce the likelihood of anthelmintic resistance developing;

(b) if the product does not achieve the desired clinical effect, as other diseases, nutritional disturbances or anthelmintic resistance may be present.

Levacide Pour-On may be administered to pregnant or lactating animals but care should be taken when treating heavily pregnant animals or animals suffering stress from adverse weather conditions, poor nutrition, penning, handling etc.

Side effects:
At the recommended dose rates, animals should not show any adverse effects. However, local skin irritation at the application site may be observed occasionally, characterised by subcutaneous oedema. Severe cases may show signs of epidermal flaking for which symptomatic treatment is recommended.

Pharmaceutical Precautions

Do not store above 25ÂșC. Store out of reach of children. Do not freeze. Protect from light.
Store tightly closed in original container. Following withdrawal of the first dose, use the product within 6 months. Discard unused material.

Further Information

Levamisole belongs to the Imidazothiazole (2-LM) class of anthelmintics.

In cases of lungworm infection coughing may persist for a considerable time following successful treatment. This is due to tissue damage caused by the parasites.

After dosing animals should be moved to clean pasture. If this is not possible retreatment at regular intervals may be required to prevent re-infection.
