After the physical examination, the doctor will ask to take a sample of the patient’s cerebrospinal fluid to confirm whether there are viruses, bacteria, and fungi that cause meningitis.

Doctor Usually not Perform any treatment until they determine the cause. However, in an emergency, they will assume that a person has bacterial meningitis and will be treated with antibiotics immediately.

according to Current treatment plan, In the case of bacterial meningitis, the doctor will consider a person’s age and medical history before using appropriate antibiotics.

Adults 18-49 years old usually receive ceftriaxone or vancomycin by needle or intravenous (IV).

People over 50 or with a weakened immune system will also receive ceftriaxone IV or vancomycin IV, but doctors may also consider ampicillin IV.

To reduce inflammation of the meninges, a person may receive steroid treatment. However, more research is needed to determine whether steroids are an effective and safe treatment for bacterial meningitis.

In the case of fungal meningitis, the doctor Will manage Antifungal drugs to clear the infection.
