Cattle (pre-ruminant cattle and new-born calves), pigs

Pre-ruminant cattle:

Treatment of gastro-intestinal infections caused by Escherichia coli susceptible to paromomycin.

Treatment of infections caused by diagnosed Cryptosporidium parvum, by reduction of diarrhoea and reduction of faecal oocyst shedding. Administration has to start within 24 hours after the onset of diarrhoea.

Pigs:

Treatment of gastro-intestinal infections caused by Escherichia coli susceptible to paromomycin.

Do not use in animals with known hypersensitivity to paromomycin, other aminoglycosides or any of the excipients. Do not use in cases with impaired function of the kidneys or liver. Do not use in ruminating animals. Do not use in turkeys due to the risk of selection for antimicrobial resistance in intestinal bacteria.

Cross-resistance has been shown between paromomycin and neomycin in Enterobacterales. Use of the product should be carefully considered when susceptibility testing has shown resistance to aminoglycosides because its effectiveness may be reduced.” Treatment with the veterinary medicinal product reduced the impact of cryptosporidiosis on the daily bodyweight gain.

The use of the veterinary medicinal product should be combined with good management practices e.g. good hygiene, proper ventilation, no overstocking. Since the product is potentially ototoxic and nephrotoxic, it is recommended to assess kidney function. Special care should be taken when considering administration of the veterinary medicinal product to newborn animals due to the known higher gastrointestinal absorption of paromomycin in neonates. This higher absorption could lead to an increased risk of oto-and nephrotoxicity. The use of the veterinary medicinal product in calves of 5 days or less should be based on benefitrisk assessment by the responsible veterinarian. As with any antiparasiticide, frequent and repeated use of antiprotozoals from the same class may lead to the development of resistance. Use of the product should be in accordance with official, national and regional antimicrobial policies. Use of the product should be based on identification and susceptibility testing of the target pathogen(s). If this is not possible, therapy should be based on epidemiological information and knowledge of susceptibility of the target pathogens at farm level, or at local/regional level.

The uptake of medication by animals can be altered as a consequence of illness. In case of insufficient uptake of water/milk animals should be treated parenterally using a suitable injectable veterinary medicinal product following the advice of the veterinarian. Prolonged or repeated use of the veterinary medicinal product should be avoided by improving management practices and through cleansing and disinfection. Use of the veterinary medicinal product deviating from the given instructions may increase the prevalence of bacteria resistant to paromomycin and may decrease the effectiveness of treatment with aminoglycosides due to the potential for crossresistance. Aminoglycosides are considered as critical in human medicine. Consequently, they should not be used as a first intention antimicrobial treatment in veterinary medicine.

Calves should only receive the treatment upon confirmation of cryptosporidial oocysts in their faeces. The product should only be used in individual animals. Do not use on an empty stomach. For treatment of anorexic calves, the product should be administered in half a litre of an electrolyte solution. The animals should receive enough colostrum according to good breeding practice.

- This product contains paromomycin and benzyl alcohol, which can cause allergic reactions in some people.

- People with known hypersensitivity (allergy) to paromomycin or any other aminoglycosides and/or benzyl alcohol should avoid contact with the veterinary medicinal product.

- This product is slightly irritant to the eye. Avoid contact with the skin and eyes.

- Personal protective equipment consisting of protective clothing and impervious gloves should be worn when handling the veterinary medicinal product.

- In the event of accidental contact with the skin or eyes, rinse with plenty of water.

- If you develop symptoms following exposure, such as skin rash, you should seek medical advice and show the physician this warning. Swelling of the face, lips and eyes or difficulty in breathing are more serious symptoms and require urgent medical attention.

- Do not eat, drink and smoke when handling the veterinary medicinal product.

- Do not ingest. In case of accidental ingestion, seek medical advice immediately and show the label to the physician.

- Wash hands after use.

In rare occasions soft faeces have been observed. Aminoglycoside antibiotics such as paromomycin can cause oto- and nephrotoxicity.

Laboratory studies in the rat and rabbit have not produced any evidence of teratogenic, foetotoxic or maternotoxic effects. The use is not recommended during pregnancy.

General anaesthetics and muscle relaxing products increase the neuro-blocking effect of aminoglycosides. This may cause paralysis and apnoea. Do not use concurrently with strong diuretics and potentially oto- or nephrotoxic substances.

Oral use. To ensure a correct dosage bodyweight should be determined as accurately as possible.

Duration of treatment: 3-5 days. Administration in milk/milk replacer. Recommended dosage: 1.25 – 2.5 ml of veterinary medicinal product/10 kg BW/day, equivalent to 17500 - 35000 IU of paromomycin per kg BW/day (i.e. approximately 25-50 mg paromomycin sulfate per kg BW/day).

Duration of treatment: 5 days. Administration in milk/milk replacer or directly in the mouth using either a syringe or an appropriate device for oral administration. Recommended dosage: 7.5 ml of veterinary medicinal product/10 kg BW/day for 5 consecutive days, i.e. 105000 IU of paromomycin per kg BW/day for 5 consecutive days (i.e. approximately 150 mg paromomycin sulfate per kg BW/day). In case of insufficient uptake of milk, the totality of the remaining solution should be administered orally directly into the mouth of the animal.

Duration of treatment: 3-5 days. Administration in drinking water. Recommended dosage: 1.25 – 2 ml of veterinary medicinal product/10 kg BW/day, equivalent to 17500 - 28000 IU of paromomycin per kg BW/day (i.e. approximately 25-40 mg paromomycin sulfate per kg BW/day).

For the administration through the drinking water the exact daily amount of veterinary medicinal product should be based on the number of the animals to be treated, and the recommended dose calculated according to the following formula:

The uptake of medicated water depends on several factors including clinical conditions of the animals and the local conditions such as ambient temperature and humidity. In order to obtain the correct dosage, uptake of drinking water has to be monitored and the concentration of paromomycin has to be adjusted accordingly. Medicated drinking water/milk/milk replacer and any stock solutions should be freshly prepared every 6 hours (in milk/milk replacer) or every 24 hours (in water).

After administration of 1X, 2X and 3X the recommended dose for the treatment of cryptosporidiosis (150, 300 and 450 mg of paromomycin sulfate/kg) during 3 times the recommended duration (15 days), in newborn calves (5-13 days) histopathological kidney abnormalities has been observed in some calves. These abnormalities can be observed in calves without any treatment however a nephrotoxicity related to the treatment cannot totally be ruled out. At 3X the recommended dose, administration to newborn calves induced a slight loss of appetite, reversible at the end of the treatment period. The decrease of the milk consumption had a limited impact on the body weight gain. At 5X the recommended dose, administration to newborn calves induced severe inflammation of the gastrointestinal tract and necrozing inflammation of the urinary bladder. Repeated overdose (at 5X) may be associated with death.

- Colibacillosis: Dosage: 25-50 mg/kg/day for 3 to 5 days. Meat and offal: 20 days

- Cryptosporidiosis: Dosage: 150 mg/kg/day for 5 days. Meat and offal: 110 days

Meat and offal:3 days

Due to the accumulation of paromomycin in the liver and kidneys, any repeated courses of treatment during the withdrawal period should be avoided.
