When cattle have to graze on pasture contaminated with infective larvae of cattle nematodes, treatment with PANOMEC Injection given at the recommended dosage of 0.2 mg per kg bodyweight controls re-infection with:

Prolonged activity

Lungworm- Dictyocaulus viviparus

up to 28 days

Brown stomach worm - Ostertagia ostertagi

up to 21 days

Nodular worm - Oesophagostomum radiatum

up to 21 days

Small intestinal worm - Cooperia spp.

up to 14 days

Hairworm - Trichostrongylus axei

up to 14 days

Barbers pole worm - Haemonchus placei

up to 14 days

To obtain optimal benefit from the persistent activity of PANOMEC Injection for grazing animals it is recommended that calves which are set-stocked in their first grazing season should be treated 3, 8 and 13 weeks after the day of turn-out. This can protect the animals from parasitic gastro-enteritis and lungworm disease throughout the grazing season, provided they are set-stocked, all the calves are included in the programme and that no untreated cattle are added to the pasture.

Treated calves should always be monitored according to good husbandry practices.

Dosage and administration

Cattle: Dosage

1 ml per 50 kg bodyweight (based on a recommended dosage level of 200 micrograms ivermectin per kg bodyweight).


Inject subcutaneously under the loose skin in front of or behind the shoulder. A sterile 17 gauge ½ inch needle is recommended.

Sheep: Dosage

0.5 ml per 25 kg bodyweight (based on a recommended level of 200 micrograms ivermectin per kg bodyweight).


Inject once subcutaneously in the neck, using aseptic precautions; a sterile 17 gauge ½ inch needle is recommended. For the treatment and control of Psoroptes ovis (sheep scab), two injections with a seven day interval are required to treat clinical signs of scab and to eliminate mites.

Pigs: Dosage

1 ml per 33 kg bodyweight (based on a recommended level of 300 mcg ivermectin per kg bodyweight).


The recommended route of administration is by subcutaneous injection into the neck using aseptic technique and a 17 gauge ½ inch needle.

To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of the dosing device should be checked.

Syringes must be filled from the vial through a dry sterile draw-off needle that has been placed in the vial stopper. Vial stoppers must not be broached more than 20 times.

When treating groups of animals use only an automatic dosing device (with vented draw-off apparatus when using the 50 ml vial).

When treating individual sheep, a syringe not exceeding 2 ml and calibrated in increments of 0.1 ml should be used.

Each ml contains 10mg of ivermectin sufficient to treat 50kg of bodyweight of cattle and sheep and 33kg of bodyweight of pigs. The injection may be given with any standard automatic or single-dose or hypodermic syringe. Use of a 17 gauge x ½ inch needle is suggested.

Replace with a fresh sterile needle after every 10 to 12 animals.

Injection of wet or dirty animals is not recommended.

PANOMEC Injection for Cattle, Sheep and Pigs can be administered to beef cows and ewes at any stage of pregnancy or lactation provided that the milk is not intended for human consumption, and to sows at any stage of pregnancy or lactation. It can be used in breeding ewes, rams, sows and boars and will not affect fertility. PANOMEC Injection for Cattle, Sheep and Pigs can be given to all ages of animals including young calves, lambs and piglets.When treating pigs and sheep of less than 16kg, seek veterinary advice regarding the use of 1ml disposable syringes graduated in increments of 0.1 ml.

Contra-indications, warnings, etc

For animal treatment only.

This product is not for intravenous or intramuscular use.

Care should be taken to avoid the following practices because they increase the risk of 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.

- underdosing, which may be due to underestimation of bodyweight, 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 macrocyclic lactones (which includes ivermectin) has been reported in Teladorsagia spp. in sheep and in Cooperia spp. in cattle within the EU. Therefore, the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Do not smoke, eat or drink while handling the product.

Wash hands after use.

Take care to avoid self-injection: the product may cause local irritation and/or pain at the site of injection. Read package leaflet before use.

PANOMEC Injection for Cattle, Sheep and Pigs has been formulated specifically for use in those species. It should not be used in other species as severe adverse reactions, including fatalities in dogs, may occur.

Treatment of psoroptic mange (sheep scab) with one injection is not recommended, because although a clinical improvement may be seen, elimination of all mites may not occur.

Sheep scab (Psoroptes ovis) is an extremely contagious external parasite of sheep. Following treatment of infected sheep, great care must be taken to avoid re-infestation, as mites may be viable for up to 15 days off the sheep. It is important to ensure all sheep which have been in contact with infected sheep are treated. Contact between treated infected and non-treated, non-infected flocks must be avoided until at least 7 days after the last treatment.

Further information

Transitory discomfort has been observed in some cattle following subcutaneous administration. A low incidence of soft tissue swelling at the injection site has been observed. Immediately following subcutaneous injection, activity suggesting pain, sometimes intense but usually transient, has been observed in some sheep. Mild and transient pain reactions may be seen in some pigs following subcutaneous injection. All of these reactions have disappeared without treatment.

In cattle, single doses of 4mg ivermectin per kg (20 x the usual level) given subcutaneously resulted in ataxia and depression. In sheep, dose levels up to 4mg per kg (20 x the usual level) given subcutaneously resulted in ataxia and depression. In pigs, a dose of 30mg ivermectin per kg (100 x the recommended dose) injected subcutaneously into pigs caused lethargy, ataxia, bilateral mydriasis, intermittent tremors, laboured breathing and lateral recumbency. No antidote has been identified, however, symptomatic therapy may be beneficial.

PANOMEC Injection has been used concurrently without adverse effects with clostridial vaccine, given at separate injection sites. Adequate vaccination of sheep against clostridial infections is strongly recommended.

Can this be used for oral administration for guinea pigs

Can this be used for oral administration for guinea pigs

  • Veterinary Advisor

This product is not licensed for use this way and so only your own vet is allowed to advise you to use an unlicensed medication for your animals. However I can say that Panomec is widely used in Guinea Pigs, usually as a treatment for mange. It is effective against other parasites too and appears to be very safe if used at an appropriate dose (which your vet could advise you on). It can be given orally or by injection. There are other products, such as Xeno 450, which contain the same active ingredient (ivermectin) and are recommended for use in Guinea Pigs, so you could look at that.
