Are there any substances I need to avoid while on the treatment?

Yes, a few. Nitrous oxide (N2O), for example, is known to kill NA, even in the small amounts from whipped cream so N20 should be avoided completely.

Antibiotics may kill the larvae, but, in most cases they will only stop them working for up to 8 weeks.  We encourage everyone (not just symbiont hosts) to try to find alternatives to antibiotics where possible.

T. Trichiura are less likely to be affected due to the way they feed and attach to the colonic mucosa.

Some forms of certain natural substances that are known to be antibacterial or antihelminthic (e.g. some concentrated herbal tinctures or extracts) may also affect the worms as would any known antihelminthic medication.

For a comprehensive list of substances that may affect NA larvae, please see the Human Helminth Care Manual.
