If you're considering a steroid injection for your nasal allergies, you may be wondering how long it will take for the injection to work. The answer depends on a few factors, including the type of steroid injection you receive and the severity of your allergies.
Steroid injections are typically given as a shot into the muscle or as a nasal spray. The most common type of steroid injection is called triamcinolone acetonide, and it usually takes effect within a few hours. If you have a more severe allergy, you may be given a higher dose of the steroid, which can take up to a week to take effect.
Steroid injections are usually given once or twice a year, and they can be an effective way to manage your allergies. If you have severe allergies, you may need to receive more frequent injections.
