Mercury is still used in some diuretics, although substitutes such as thiazides now exist for most therapeutic uses. [79] In 2003, mercury compounds were found in some over-the-counter drugs, including topical antiseptics, stimulant laxatives, diaper-rash ointment, eye drops, and nasal sprays.

Concerns about thiomersal and vaccines are commonly expressed by anti-vaccine activists. Claims relating to the safety of thiomersal, a mercury-based preservative used in vaccines, are refuted, but still subject to fearmongering, notably claims it could cause neurological disorders such as autism, leading to its removal from most vaccines in the US childhood schedule.

Mercury cannot be used below the temperature at which it becomes solid, −38.83 °C (−37.89 °F). If the thermometer contains nitrogen, the gas may flow down into the column when the mercury solidifies and be trapped there when the temperature rises, making the thermometer unusable until returned to the factory for reconditioning.
No mercury is used in the manufacturing of LED lamps, a different technology replacement for incandescent lamps. [158] In addition, LED lamps do not require warmup time in cold weather, and in fact, perform better in colder temperatures, making them an excellent choice for use in cold locations, such as refrigeration units.
For 1939, the Mercury was launched at a starting price of US$916 ($20,706 in 2024 dollars [10]); over 65,800 vehicles were sold in the inaugural model year.
