Name some Drugs to prvent tuberculosis
Pyrazinamide can cause morbilliform rash, arthralgias and asymptomatic hyperuricemia, and blocks the hypouricemic action of allopurinol (Zyloprim, and others). Gastrointestinal disturbances and hepatotoxicity can occur. Ethambutol can cause optic neuritis, but this is very rare when using a dosage of 15 mg/kg daily. Testing of visual acuity should be performed at the start of therapy, and monthly if the drug is continued past 2 months. The decision to use ethambutol in children too young to have visual acuity monitored must take into consideration the risk/benefit for each particular patient.
