Animal Drug Safety-Related Labeling Changes
This online resource provides information on recently approved safety-related labeling changes for animal drugs from January 2021 forward in an effort to improve transparency and communication with veterinarians and the public.
When adverse events are reported or safety concerns are identified for an animal drug, the FDA may work with the sponsor to revise the labeling to reflect this information. This webpage includes safety-related labeling changes initiated by the company or the FDA. Awareness of these safety-related labeling changes is essential for the safe use and administration of FDA-approved animal products.
There is often a lag between the approval of labeling changes and the new labeling becoming available in the marketplace. You can check this webpage for recent safety-related labeling changes as it will be updated on a regular basis when changes to the drug labeling are approved by the FDA. Safety-related labeling change information will be available here for two years after it is first listed.
For more information about the most current labeling for a particular animal drug, veterinarians should reach out to the drug’s sponsor.
Disclaimer
This webpage reflects recently approved safety-related labeling changes for FDA approved brand name new animal drugs and is also applicable to any generics of those products. Generic new animal drugs are copies of brand name new animal drugs approved by the FDA and must provide the same labeling information (e.g., Indications, Warnings, Cautions, etc.). Therefore, the safety-related labeling changes reflected on this webpage also apply to generic new animal drugs
The labeling for an approved animal drug, such as its carton or package insert, might not reflect the changes for a year or more in the marketplace as the drug company distributes its inventory of the drug with labeling printed prior to the approval of the labeling changes.
Any reference to a commercial product, process, service, or company is not an endorsement or recommendation by the U.S. government, the Department of Health and Human Services, the FDA or any of its components. The FDA is not responsible for the contents of any non-FDA website referenced by or linked to the agency's website.
Indications:
For suppression of estrus in mares. Suppression of estrus allows for a predictable occurrence of estrus following drug withdrawal. This facilitates the attainment of regular cyclicity during the transition from winter anestrus to the physiological breeding season. Suppression of estrus will also facilitate management of prolonged estrus conditions. Suppression of estrus may be used to facilitate scheduled breeding during the physiological breeding season.
Summary of Changes:
- A new subsection, Reported Human Effects from Exposure, was added to the User Safety Warnings section.
- Labeling revisions emphasize protective measures for users, including the use of appropriate protective gloves. Adequate protection minimizes human exposure to the drug.
- New language alerts to the risk of non-user exposure to contaminated surfaces or equipment. Users are directed to prevent such exposure by adequately decontaminating any equipment or surfaces that come in contact with Regumate.
- Instructions for the correct use of the Regumate dosing device have been added, as a safety measure to minimize human exposure.
The following safety-related changes were made to the labeling:
(Additions and/or revisions underlined)
DOSAGE AND ADMINISTRATION:
Administer solution orally at the rate of 1 mL per 110 pounds body weight (0.044 mg/kg) once daily for 15 consecutive days. Administer solution directly on the base of the mare's tongue or on the mare's usual grain ration.
(Dosage Chart – no changes)
When handling Regu-Mate product, the dosing device, or syringes, always use vinyl, neoprene, or nitrile gloves. Latex gloves are not protective. The product may be dosed using Regumate Equine Dosing Device or a luer lock syringe. Use of the RegumateEquine Dosing Device is recommended to reduce the risk of human exposure. Follow all instructions when using the dosing device. Do not use any dosing device other than the Regumate Equine Dosing Device.
For use with Regumate Equine Dosing Device, first assemble the device according to directions supplied with the Regumate Equine Dosing Device. Remove the shipping cap and seal on Regumate (altrenogest) bottle. Store the cap in a clean and dry location. Apply downward force and fasten the quick connect cap with dip tube onto the product bottle. The flexible dip tube will contact the bottom of the product bottle and bend slightly. Turn the dose selection dial to 15. Hold the dosing device vertically with the nozzle on the top. Direct the opening of the nozzle away from any person and cover it with absorbent material. Slowly squeeze and release handle until air in the barrel is expelled and product starts to come out. Prime the device by expelling two (2) doses of 15 mL of product into a waste container or absorbent material. (Re-prime the dosing device by expelling two (2) doses if air is observed inside the barrel after switching to a fresh bottle or during dosing period). Set the dose according to DOSAGE CHART provided herein by turning the dose selection dial. The dosing device is ready for use. Refer to the Regumate Equine Dosing Device label for equipment cleaning instructions.
For use with a luer lock syringe, 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 Regumatesolution and return bottle to upright position before detaching syringe. (Note: Do not remove syringe while bottle is inverted as spillage may result.) Replace cover on bottle dispensing tip to prevent leakage. Syringes used for administration should be replaced frequently and disposed of in a secure manner to prevent exposure to the product.
WARNINGS AND PRECAUTIONS:
User Safety Warnings:
Not for use in humans. Keep out of reach of children. Avoid skin contact. Regumate is absorbed through unbroken skin, and exposure may result in serious side effects to both women and men. Wear vinyl, neoprene, or nitrile gloves when handling or administering Regumate, or when touching contaminated surfaces or equipment. Latex gloves are not protective.
PREGNANT WOMEN OR WOMEN WHO MAY BE PREGNANT SHOULD NOT HANDLE REGU-MATE. WOMEN OF CHILDBEARING AGE SHOULD EXERCISE EXTREME CAUTION WHEN HANDLING THIS PRODUCT.
Accidental absorption, such as via direct contact with the skin, could lead to a disruption of the menstrual cycle or prolongation of pregnancy. Immediately wash off accidental spillage on the skin with soap and water. Any equipment or surfaces that come in contact with Regumate should be adequately cleaned and decontaminated to prevent human exposure (see Reported HUMAN Effects from Exposure).
Potential Effects of Human Exposure
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.
The list of people who should not handle this product (see below) is based upon the known effects of progestins used in humans on a chronic basis.
PEOPLE WHO SHOULD NOT HANDLE Regumate:
- Women who are or may be pregnant.
- Anyone with blood clots or clotting disorders, or with a history of these events.
- Anyone with a history of heart disease or stroke.
- Women with known or suspected breast cancer.
- People with known or suspected estrogen-dependent cancer.
- Women with vaginal bleeding of unknown cause.
- People with tumors which developed during the use of oral contraceptives or other estrogen-containing products.
- Anyone with liver dysfunction or disease.
ACCIDENTAL EXPOSURE:
Regumate is readily absorbed through the skin. In addition, this oil-based product can penetrate latex or other types of porous gloves. Always wear vinyl, neoprene, or nitrile gloves when handling Regumate. Latex gloves are not protective. If Regumate gets inside gloves by damage or spilling, the covered skin may absorb more of the drug.
IN CASE OF ACCIDENTAL EXPOSURE:
Skin exposure and/or clothing contamination: Wash skin immediately with soap and water, and launder clothing with detergent.
Eye exposure: Immediately flush with plenty of water for 15 minutes. Get medical attention. If wearing contact lenses, flush eyes immediately with water before removing lenses.
If swallowed: Do not induce vomiting. Seek medical attention immediately. Regumate contains an oil. Vomiting should be supervised by a physician because of possible pulmonary damage via aspiration of the oil base. If possible, bring the labeling to the physician.
Reported HUMAN Effects from Exposure:
These symptoms have been reported in women and men following accidental exposure to altrenogest products, including Regumate, either through handling of the product or contact with contaminated surfaces.
- Adverse reproductive effects reported in women included abnormal or absent menstrual cycles.
- Adverse reproductive effects in men included decreased libido.
- Other adverse effects reported in women and men included headaches, fever, abdominal pain, nausea, diarrhea, vomiting, and rashes.
ANIMAL SAFETY WARNINGS AND PRECAUTIONS:
Keep Regumate in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.
Various synthetic progestins, including altrenogest, when administered to rats during the embryogenic stage of pregnancy at doses manyfold greater than the recommended equine dose, caused fetal anomalies, specifically masculinization of the female genitalia.
OTHER WARNINGS:
Do not use in horses intended for human consumption.
