Drug-induced aseptic meningitis

Drug-induced aseptic meningitis is a rare adverse effect of certain medications. This condition is an inflammation of the meninges, which are the protective membranes covering the brain and spinal cord, that is not caused by bacterial infection and occurs as a result of drug use.

Causes

Drug-induced aseptic meningitis is caused by the use of certain drugs. These include nonsteroidal anti-inflammatory drugs (NSAIDs), intravenous immunoglobulin (IVIG), and certain antibiotics. The exact mechanism by which these drugs cause aseptic meningitis is not fully understood, but it is believed to involve an allergic reaction or hypersensitivity to the drug.

Symptoms

The symptoms of drug-induced aseptic meningitis are similar to those of other forms of meningitis and include headache, fever, and neck stiffness. Other symptoms may include nausea, vomiting, sensitivity to light, and altered mental status.

Diagnosis

Diagnosis of drug-induced aseptic meningitis is made based on the patient's symptoms, medical history, and the results of certain diagnostic tests. These tests may include a lumbar puncture to collect and analyze cerebrospinal fluid, and blood tests to rule out other causes of meningitis.

Treatment

Treatment of drug-induced aseptic meningitis involves discontinuing the offending drug and providing supportive care to relieve symptoms. In some cases, corticosteroids may be used to reduce inflammation.

Prognosis

The prognosis for drug-induced aseptic meningitis is generally good, with most patients recovering fully once the offending drug is discontinued. However, in some cases, the condition may recur if the patient is re-exposed to the drug.
