Smelling salts have been used for centuries, primarily to revive those who have fainted or lost consciousness. Due to their strong smell and irritation of the nasal passages, they promote a quick recovery. However, many companies market smelling salts to help consumers become more alert and energetic. However, this can cause a number of potentially serious side effects or health problems.

The U.S. Food and Drug Administration (FDA) issued a warning about smelling salts on August 6, urging consumers not to use smelling salts to boost energy. The products are unapproved drugs and can cause seizures, constriction of the airways and other serious injuries.

In recent years, the number of reported adverse events related to smelling salts’ side effects has risen sharply, according to federal regulators, from just six cases in 2022 to at least 26 problems identified in 2023. Reported problems included shortness of breath, migraines, vomiting, diarrhea, fainting and seizures.

FDA targets illegal marketing of smelling salts

Many smelling salts currently on the market are touted as a means of increasing alertness, energy and athletic performance. They are promoted with claims that they awaken the senses and provide “laser-like concentration.” One company even promotes its mint-scented version as a means of “increasing alertness and aggressiveness.”

However, the FDA has now sent warning letters to companies marketing these unapproved products, pointing out that these claims are unfounded. The products in question primarily contain ammonia. Ammonia is a chemical commonly used in cleaning products and can quickly cause coughing, constriction of the airways and irritation of the eyes, nose or throat.
