Wells Welcome back to RoshCast for Episode 47!&nbsp;Let’s kick off this episode with a review of Neisseria meningitides, an important topic for clinical practice and personal safety. * Neisseria meningitides is highly contagious and antibiotic prophylaxis is indicated for close contacts of an infected patient, including those in contact with secretions as well as members of the same household or daycare center.* Healthcare workers with close contact with the patient’s secretions should also receive prophylaxis.* There are three options for prophylaxis: * Rifampin is administered at a dose of 10 mg/kg with a max dose of 600 mg every 12 hours for 4 doses, and this is 100% effective as far as we know.* Ceftriaxone 250 mg IM can be given for 1 dose, which is 97–100% effective.* The least effective option is Ciprofloxacin 500 mg PO for 1 dose, and that’s 90–95% effective. * Even though rifampin is the most effective, be wary of its side effects, which include turning secretions like tears and urine orange. Contact lens wearers should be warned of permanent staining.
