The safety of the product has not been investigated during the 1st and 2nd third of pregnancy. Do not use in pregnant dogs during the 1st and 2nd third of pregnancy (see Contra-Indications, Warnings etc).

A single treatment during the last third of pregnancy or during lactation has been demonstrated safe.

Contra-indications, warnings, etc

Do not use in case of hypersensitivity to the active substances or to any of the excipients.

Do not use during the 1st and 2nd third of pregnancy.

Fleas serve as intermediate hosts for one common type of tapeworm - Dipylidium caninum. Tapeworm infestation is certain to re-occur unless control of intermediate hosts such as fleas, mice etc. is undertaken.

Parasite resistance to any particular class of anthelmintic may develop following frequent, repeated use of an anthelmintic of that class.

To minimise the risk of re-infestation and new infestation, excreta should be collected and properly disposed of for 24 hours following treatment.

In very rare cases mild and transient digestive tract disorders (e.g. vomiting) may occur.

The frequency of adverse reactions is defined using the following convention:

- very rare (less than 1 animal in 10,000 animals, including isolated reports).

The anthelmintic effects of this product and piperazine containing products may be antagonised when the two drugs are used together.

10 times the recommended dose of the product was tolerated without signs of adverse reactions in dogs and pups.

Since it contains praziquantel, the product is effective against Echinococcus spp. which do not occur in all EU member states but are becoming more common in some. Echinococcosis represents a hazard for humans. As echinococcosis is a notifiable disease to the World Organisation for Animal Health (OIE), specific guidelines on the treatment and follow-up, and on the safeguard of persons, need to be obtained from the relevant competent authority.
