Description
Promethazine is a first-generation antihistamine used to help manage symptoms of allergies and hay fever, including sneezing, runny nose, itchy or watery eyes, and skin reactions such as hives or itching. It works by blocking the effects of histamine, a chemical released during allergic responses, which causes inflammation and irritation in the body.
This medication is particularly useful for individuals who experience moderate to severe allergic reactions that affect their quality of life or sleep. Unlike newer antihistamines, promethazine has a sedating effect, which makes it a helpful option for those whose allergy symptoms interfere with sleep. It is also often prescribed when allergies are accompanied by skin problems like rashes or severe itching.
Promethazine is usually taken in tablet form once or twice a day, depending on the severity of the symptoms. Because of its calming effect, it is often taken in the evening or before bedtime. The sedative effect not only relieves allergy symptoms but also helps the body rest, making it especially suitable for nighttime use.
The effects typically begin within 20 to 60 minutes after taking a dose and can last for several hours. Some people may experience drowsiness, dizziness, or dry mouth, especially during the first few days of use. These side effects often decrease as the body adjusts. It’s important not to drive or operate machinery after taking promethazine until you know how it affects you.
