Treatment and Outcomes for Pneumocystis pneumonia
PCP requires treatment with prescription medicine that must be taken for three weeks. The best form of treatment for PCP is trimethoprim sulfamethoxazole (TMP-SMX), which is also known by the brand names Bactrim, Septra, and Cotrim. This medicine is given orally or through a vein.
TMP-SMX can cause negative side effects such as a rash and nausea, but the benefits of treating the PCP usually outweigh the risks of these side effects. Without treatment, PCP can be fatal.
