Accidental spillage on the skin should be washed off immediately with soap and water. Wash hands after treatment and before meals.

• In case of accidental contact with eye, rinse abundantly with water. Get medical attention.

• Effects of overexposure: Repeated accidental absorption could lead to disruption of the menstrual cycle, uterine or abdominal cramping, increased or decreased uterine bleeding, prolongation of pregnancy or headache.

(iii) Other precautions regarding impact on the environment

When spreading manure from treated animals, the minimum distance to surface water as defined in the national or local regulations has to be strictly respected, because the manure may contain altrenogest which could cause adverse effects in the aquatic environment.

Group feeding on the floor:

Feed should be presented in such a manner that each pig is allowed sufficient floor space to get equal access to the feed.

Once the animals have started feeding, dispense one dose of Regumate as a topdressing on the feed in front of each pig.

Administration of product supplied in 540 ml and 1L container (not pressurised):

- Remove the cap and the obturator.

5. PHARMACOLOGICAL PROPERTIES

Pharmatherapeutic group: Sex hormones and modulators of the genital system, Progestogens, Other progestogens.

ATC Vet Code: QG03DX90

5.1 Pharmacodynamic properties

Altrenogest has a similar action to the natural hormone progesterone. When administered orally it suppresses the normal sexual cycle, preventing signs of heat and ovulation. Withdrawal of Regumate then allows the natural hormones to be released again and animals return to heat in a synchronised fashion.

5.2 Pharmacokinetic particulars

Altrenogest is rapidly absorbed following oral administration, with peak plasma concentrations being reached between 1 and 4 hours after treatment. The liver is the main organ involved in altrenogest's metabolism and biliary excretion is its main route of elimination. Following treatment, circulating altrenogest concentrations decline biphasically. Half life of elimination was estimated to be around 14 hours.
