The antibiotics erythromycin, clarithromycin, or azithromycin are typically the recommended treatment. Newer macrolides are frequently recommended due to lower rates of side effects. Trimethoprim-sulfamethoxazole (TMP/SMX) may be used in those with allergies to first-line agents or in infants who have a risk of pyloric stenosis from macrolides. A reasonable guideline is to treat people age >1 year within 3 weeks of<unk>  onset and infants age <1 year and pregnant women within 6 weeks of<unk>  onset. If the person is diagnosed late, antibiotics will not alter the course of the illness, and even without antibiotics, they should no longer be spreading pertussis. When used early, antibiotics decrease the duration of infectiousness, and thus prevent spread. Short-term antibiotics (azithromycin for 3–5 days) are as effective as long-term treatment (erythromycin 10–14 days) in eliminating B. pertussis with fewer and less severe side effects. People with pertussis are most infectious during the first two weeks following the onset of symptoms. Effective treatments of the<unk>  associated with this condition have not been developed. The use of over the counter<unk>  medications is discouraged and has not been found helpful.
