  10. Management
    1. Emergency department empiric treatment
      1. Initiating empiric treatment for suspected STD prior to results (often delayed days) is appropriate
      2. Despite risk of overtreatment, treat for suspected Chlamydia and Gonorrhea (prevents spread, complications)
        1. Ceftriaxone 250 mg IM AND
        2. Azithromycin 1 gram orally (or Doxycyline 100 bid x7 days if Azithromycin allergic)
    2. Rescreening
      1. Routinely Rescreen positive STD cases in 3 months to identify new STD infections

    3. Expedited Partner Treatment
      1. Precaution: Legality of Expedited Partner Treatment varies by State in the United States
        1. http://www.cdc.gov/std/ept/legal/
      2. Ideally sexual partners are seen for their own medical evaluations
        1. However: Delaying their treatment until evaluation risks re-exposing treated patients
      3. CDC asks physicians to consider treating sexual partners of STD patients without a visit
        1. Employ in cases where sexual partner is unlikely to present for medical care
        2. Prescription for sexual partner's STD treatment is given to the patient being treated
        3. Some states may allow prescription labeled for "EPT" or "partner"
        4. Do not double up on prescription quantity for one patient (write 2 separate prescriptions)
      4. Example protocol for partner (prescriptions given to patient to bring to partner)
        1. Provider should ask about partner's medication allergies, other medications and pregnancy
        2. Cefixime 400 mg (if partner will be seen, Ceftriaxone 250 mg IM/IV is preferred) AND
        3. Azithromycin 1 gram orally
        4. Patient and their partner should abstain from sex for 7 days after completing course

Sexually Transmitted Diseases (C0036916)

Definition (MEDLINEPLUS)

Sexually transmitted diseases (STDs) are infections that you can get from having sex with someone who has the infection. The causes of STDs are bacteria, parasites and viruses. There are more than 20 types of STDs, including

Most STDs affect both men and women, but in many cases the health problems they cause can be more severe for women. If a pregnant woman has an STD, it can cause serious health problems for the baby.

If you have an STD caused by bacteria or parasites, your health care provider can treat it with antibiotics or other medicines. If you have an STD caused by a virus, there is no cure. Sometimes medicines can keep the disease under control. Correct usage of latex condoms greatly reduces, but does not completely eliminate, the risk of catching or spreading STDs.
