To mark International Pet Day on April 11, the Federal Office of Consumer Protection and Food Safety (BVL) is warning against the accidental transfer of hormone-containing medicines from humans to pets. Petting, carrying or other physical contact can inadvertently expose pets to hormones and, in the worst case, cause serious side effects. A few simple measures can help to reduce this risk.

As part of hormone therapy in humans, topical medications in the form of gels, creams or sprays are often used. They contain active ingredients such as the hormones estradiol or testosterone. The medication is regularly applied to certain parts of the body, such as the forearm or shoulder.

"If pets have close physical contact with a treated person, they can also be unintentionally exposed to the active ingredient and develop serious side effects," warns veterinarian Dr. Ann Neubert, expert on side effects of medicinal products at the Federal Office of Consumer Protection and Food Safety (BVL). The hormones can be absorbed both through the skin and orally when licked. "Pets sometimes show a variety of symptoms after contact with hormone preparations, which differ depending on the animal species and hormone," emphasizes Neubert. If such a reaction occurs, a veterinary practice should definitely be consulted and informed of possible contact with hormone preparations.

"Simple measures can help to prevent side effects in pets in the first place," advises the expert. Thorough hand washing after applying hormone preparations reduces the risk of unintentional transmission, as does carefully covering the treated skin areas with clothing. After consultation with the treating doctor, it may also be helpful to choose a different skin area for treatment, to carry out the treatment at a different time of day or even to switch to a medication with a different route of administration.
