when chlamydia is ruled out, monotherapy without the use oƒ oral
azithromycin/doxycycline is better do reduce the risk oƒ resistance.
So, iƒ someone has signs and symptoms oƒ gonorrhea and chlamydia
treatment is: Ceƒtriaxone 500 mg intramuscularly in a single dose

Bacterial
Vaginosis
Metronidazole P.O and Metronidazole gel or Clindamycin cream
The ƒollowing three regimens are recommended as ƒirst-line therapy
ƒor the treatment oƒ bacterial vaginosis in nonpregnant women. It is
important to note that the single 2-gram dose oƒ
oral metronidazole is no longer recommended ƒor the treatment oƒ
bacterial vaginosis.
• Metronidazole 500 mg orally twice a day ƒor 7 days, or
• Metronidazole gel 0.75%, one ƒull applicator (5 grams)
intravaginally once daily ƒor 5 days, or
• Clindamycin vaginal cream 2%, one ƒull applicator (5 grams)
inserted at bedtime ƒor 7 days
Any oƒ the recommended bacterial vaginosis treatments ƒor
nonpregnant women (oral metronidazole, metronidazole gel, and
clindamycin cream) as well as certain alternative regimens (oral
clindamycin and clindamycin ovules) can be used to treat women
with symptomatic bacterial vaginosis during pregnancy.
Not saƒe ƒor pregnancy: Tinidazole, secnidazole, metronidazole 1.3%
vaginal gel, the 750-mg vaginal metronidazole tablets, and the
Clindesse brand oƒ 2% clindamycin vaginal cream, which is a high-
dose single application treatment ƒor bacterial vaginosis.
, NR566 Ƒinal Study Guide
Ƒor breastƒeeding mothers with symptomatic bacterial
vaginosis, metronidazole can be used.

▪ Acyclovir 200 mg PO 5 times a day 7-10 days
▪ Valacyclovir 1g OR BID 7-10 days
▪ Ƒamciclovir 250 mg TID PO 7-10days
Antiviral therapy may have a major impact on symptoms in person
with a ƒirst clinical episode oƒ genital HSV, especially iƒ the duration
oƒ symptoms is less than 7 days at the time antiviral therapy
(acyclovir, valacyclovir, and ƒamciclovir) is started. The
recommended treatment ƒor ƒirst clinical episode oƒ genital herpes is
a 7- to 10-day course with an antiviral medication, which has been
shown to shorten the duration oƒ viral shedding, improve symptoms,
and accelerate healing.
Severe inƒection: Acyclovir
Recurrent episodes: Acyclovir, 800 mg 2 or 3 times per day. or
Acyclovir, 400 mg. or Ƒamciclovir 125 mg, 1g or 500 mg.
Valacyclovir, 500 mg or 1g
Antiviral therapy ƒor the episodic treatment oƒ genital herpes includes
three preƒerred oral medications, all with similar
eƒƒicacy: acyclovir, valacyclovir, and ƒamciclovir.
Intravenous acyclovir should be reserved ƒor persons with severe
HSV disease or complications requiring hospitalization (e.g.
disseminated inƒection, pneumonitis, or hepatitis) or complications oƒ
the central nervous system (e.g. meningitis or encephalitis).
