Paromomycin is an antibiotic, which is licensed in the United States for treating intestinal amoebiasis and giardiasis. It is not marketed in the United Kingdom, but is available for use on a named-patient basis.

Paromomycin is currently being studied as a treatment for cryptosporidiosis, alone or in combination with other drugs, with some success.1 When taken as tablets, the drug only acts in the gut where its effects are most needed. It is not absorbed into the bloodstream, which means that it will not affect Cryptosporidium in the liver. Most doctors begin with an initial dose of 500mg four times daily for 14 to 30 days, and then prescribe a maintenance dose of 500mg twice daily indefinitely.

Paromomycin’s side-effects include nausea, reversible kidney damage and possible hearing loss. A case of inflammation of the pancreas has also been reported.2

Paromomycin is manufactured by Pharmacia & Upjohn under the tradename Humatin.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
