SwineMate is a solution used to synchronization estrus in sexually mature gilts that have had at least one estrous cycle to achieve prolonged gestation for 2-3 days, synchronized farrowing and postponement of post-weaning estrus. Provides predictable breeding timetable. Encourages standing heat 4-9 days after completing the treatment.

Features & Benefits

  • Manufactured in Minnesota in an FDAapproved facility.
  • Dosage - 6.8 mL/day for 14 consecutive days (15 mg of altrenogest per day).
  • Achieve standing heat 4-9 days after SwineMate treatment.
  • The cost-effective alternative to MATRIX.
  • The exact formulation and active ingredient as MATRIX.
  • Operating efficiency improves by controlling estrus synchronization.
  • Predictable breeding timetable for sexually mature gilts that have had at least one estrus.
  • SwineMate is used to synchronize the estrous cycle of gilts, to prolong gestation for 2-3 days, to synchronize farrowing, and to postpone post-weaning estrus.

How It Works

SwineMate contains the active ingredient, altrenogest, which produces a progestational effect in mares.


While wearing protective gloves, remove shipping cap and seal; replace with enclosed plastic dispensing cap. Remove cover from bottle dispensing tip and connect luer lock syringe (without needle). Draw out appropriate volume of SwineMate solution. (Note: Do not remove syringe while bottle is inverted as spillage may result.) Detach syringe and replace cover on bottle dispensing tip to prevent leakage. Administer 6.8 mL (15 mg altrenogest) per gilt once daily for 14 consecutive days. Treat gilts on an individual animal basis by top-dressing SwineMate on a por-tion of each gilt’s daily feed allowance. To produce the desired synchronization of estrus in a group of gilts, treat all of the gilts daily for the same 14-day period.

Excessive use of a syringe may cause the syringe to stick; therefore, replace syringe as necessary.


Federal law prohibits extra-label use of this drug to enhance food and/or fiber production in animals.

Do Not Use: In gilts having a previous or current history of uterine inflammation (i.e., acute, subacute or chronic endometritis).


User/Handler Safety: Keep this and all medication out of the reach of children

Avoid skin contact. Wear vinyl, neoprene or nitrile protective gloves when handling this product. DO NOT USE LATEX GLOVES. Pregnant women or women who suspect they are pregnant should not handle SwineMate (altrenogest) Solution 0.22%. Women of childbearing age should exerciseextreme caution when handling this product. Accidental absorption could lead to a disruption of the menstrual cycle or prolongation of pregnancy. Wash off accidental spillage on the skin immediately with soap and water.

People who should not handle this product:

  1. Women who are or suspect they are pregnant.
  2. Anyone with thrombophlebitis or thromboembolic disorders or with a history of these events.
  3. Anyone with cerebral-vascular or coronary-artery disease.
  4. Women with known or suspected carcinoma of the breast.
  5. People with known or suspected estrogen-dependent neoplasia.
  6. Women with undiagnosed vaginal bleeding.
  7. People with benign or malignant tumors which developed during the use of oral contraceptives or other estrogen-containing products.
  8. Anyone with liver dysfunction or disease.

Accidental exposure:

Altrenogest is readily absorbed from contact with the skin. In addition, this oil-based product can penetrate porous gloves. Altrenogest should not penetrate intact vinyl, neoprene or nitrile protective gloves; however, if there is leakage (i.e., pinhole, spillage, etc.) the contaminatedarea covered by such occlusive materials may have increased absorption. DO NOT USE LATEX GLOVES.

The following measures are recommended in case of accidental exposure.

Skin Exposure: Wash immediately with soap and water.

Eye Exposure: Immediately flush with plenty of water for 15 minutes. Get medical attention.

If Swallowed: Do not induce vomiting. SwineMate (altrenogest) Solution 0.22% contains an oil. Call a physician. Vomiting should be supervised by a physician because of possible pulmonary damage via aspiration of the oil base. If possible, bring the container and labeling to the physician.

Effects of Overexposure:

There has been no human use of this specific product. The information contained in this section is extrapolated from data available on other products of the same pharmacological class that have been used in humans. Effects anticipated are due to the progestational activity of altrenogest. Acute effects after a single exposure are possible;however, continued daily exposure has the potential for more untoward effects such as disruption of the menstrual cycle, uterine or abdominal cramping, increased or decreased uterine bleeding, prolongation of pregnancy and headaches. The oil base may also cause complications if swallowed. In addition, the list of people who should not handle this product is based upon the known effects of progestins used in humans on a chronic basis.

Human Food Safety:

Gilts must not be slaughtered for human consumption for 21 days after the last treatment.

Environmental Safety:

Place empty drug containers and used syringes, protective gloves or other articles that come in contact with this product in a leak-resistant container for disposal in accordance with applicable Federal, state and local regulations.

Adverse Reactions and Potential Safety Hazards:

Underfeeding of SwineMate may lead to the occurrence of cystic follicles.

When Using This Product:

A small percentage (less than 5%) of treated gilts may exhibit estrus (standing heat) during the 14-day treatment period. Gilts nearing estrus at the start of the 14-day treatment period may express estrus early in that period.


Store at or below room temperature, 77° F (25° C). Close tightly.


SwineMate is used in gilts to synchronize estrus for planned breeding.

Many things might affect how well this drug will work in your animal. Be sure to discuss the following with your veterinarian so together you can make the best treatment decisions.

  • Other drugs can interact with SwineMate, so be sure to tell your veterinarian and pharmacist what medications (including vitamins, supplements, or herbal therapies) you give your animal, including the amount and time you give each.
  • Tell your veterinarian about any conditions or diseases your animal may have now or has had in the past.
  • If your animal has been treated for the same disease or condition in the past, tell your veterinarian about the treatment and how well it did or didn't work.
  • If your animal is pregnant or nursing, talk to your veterinarian about the risks of using this drug.
  • Tell your veterinarian and pharmacist about any medication side effects (including allergic reactions, lack of appetite, diarrhea, itching, hair loss) your animal has developed in the past.
SwineMate takes several doses before you will see any effect. The medication's full effects may not be evident until your animal has taken it consistently for several weeks. However, you may not see any improvement of clinical signs outwardly, so your veterinarian may need to run further tests to determine if the drug is working appropriately. The effects of this medication are moderate in duration, meaning they may last for a few days.

  • Women who are pregnant or may become pregnant.

  • Anyone with hardening of the arteries or a history of stroke.
  • Women with breast cancer or a history of breast cancer.
  • Women with estrogen dependent cancerous tumors.
  • Women who have had tumors that developed while taking estrogens or oral contraceptives.

If you, or others that may handle this product, fit any of these categories, discuss with your veterinarian whether this drug can be safely used or if other treatments may be better.
