Special warnings for each target species


Special precautions for use

Not applicable.

Operator warnings:

Women who are pregnant, or suspected to be pregnant, should not use the product. Women of childbearing age should handle the product with extreme care. The product should not be handled by persons with known or suspected progesterone-dependent tumours or thrombo-embolic disorders.

Direct contact with the skin should be avoided. Personal protective clothing (gloves and overalls) must be worn when handling the product. Porous gloves may let this product pass through. Transcutaneous absorption may be even higher when the area is covered by an occlusive material, such as latex or rubber gloves. 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 or pregnancy or headache.

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.

Adverse reactions

Ensure the correct dose is administered daily as under-dosing can lead to the formation of cystic follicles.

Use during pregnancy, lactation or lay

Do not administer to pregnant sows.


No interactions known.

Amounts to be administered and administration route

Gilts: One dose of 5 ml per gilt per day for 18 consecutive days given orally with feed for immediate consumption.

Sows: One dose of 5 ml per sow per day for 3 consecutive days given orally with feed for immediate consumption.

Administration of product supplied in pressurised 360 ml canister: Do not shake before use to avoid mixing the solution with the nitrogen included in this pressurised container. Animals should be segregated and dosed individually. Add the product as a top dressing to the feed using the metered dose applicator. Add to the surface of the feed immediately before feeding. Discard any remaining medicated feed.

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 top-dressing on the feed in front of each pig.

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

- Remove the cap and the obturator.

- Measure the clinical dose of 5 ml using the dosing cup provided.

- Pour the dose on the feed.

- Close the bottle with the obturator and the screwable cap after each use.


No special precautions required. Doses of 20 times the recommended dose did not affect pigs nor their offspring.

Withdrawal periods

Animals must not be slaughtered for human consumption during treatment. Pigs may be slaughtered for human consumption only after 9 days from the last treatment.

Pharmacological particulars

ATC Vet Code: QG03DX90

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

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.

Pharmacokinetic properties

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.

Butylated hydroxytoluene (E321), Butylated hydroxyanisole (E320) and Soya oil.
