Common Side Effects of Steroid Injections
Steroid injections are widely used for treating pain, inflammation, and various medical conditions. While generally considered safe, they can cause both local and systemic side effects. The most frequently reported side effects include flushing, local skin changes, and mild neuropsychiatric symptoms.
Flushing After Steroid Injections
Flushing, or a sudden reddening of the skin, is a well-documented side effect of steroid injections. Studies show that the incidence of flushing ranges from about 5% to 16%, depending on the type and dose of steroid used. Flushing is usually mild and temporary, occurring within hours to a couple of days after the injection. It is more common in women and with certain types of injections, but the difference between steroid types is not statistically significant 245.
Local Skin Reactions: Hypopigmentation and Atrophy
Local side effects at the injection site can include pain, hypopigmentation (lightening of the skin), and skin atrophy (thinning of the skin). Rarely, patients may develop linear hypopigmentation or atrophy, likely due to the spread of steroid crystals along lymphatic channels. These changes are usually cosmetic and not harmful, but they can be distressing for some patients 39.
Neuropsychiatric and Systemic Effects
Neuropsychiatric symptoms such as restlessness, irritability, sleep disturbances, and mood changes are rare but possible after steroid injections. These effects are more likely in patients with a history of psychiatric conditions, after higher doses, or with multiple-level injections. Most symptoms are mild and resolve within a week 16.
Systemic side effects, though less common, can include Cushing’s syndrome, increased intraocular pressure, central serous chorioretinopathy, and changes in blood sugar levels, especially in patients with diabetes. These effects are more likely with repeated or high-dose injections and should be monitored during treatment .
Menstrual Irregularities and Other Mild Side Effects
Women of reproductive age may experience menstrual irregularities after steroid injections. Other mild side effects reported include feeling unusually joyful, difficulty sleeping, cough, nasal pain, and mild airway restriction. These effects are generally short-lived and resolve after treatment ends 67.
Rare but Serious Complications
Although extremely rare, serious complications can occur. For example, blindness has been reported after facial steroid injections due to accidental blockage of the central retinal artery. This is a catastrophic but very uncommon risk, especially with facial or periocular injections .
Conclusion
Steroid injections are generally safe, but patients should be aware of possible side effects. The most common are mild and include flushing, local skin changes, and transient mood or sleep disturbances. Rarely, more serious systemic or local complications can occur, especially with repeated or high-dose injections. Patients should discuss potential risks with their healthcare provider and report any unusual symptoms after receiving a steroid injection 1234+6 MORE.
