A number of alternative health products are promoted for chronic Lyme disease,[7] of which possibly the most controversial and harmful is long-term antibiotic therapy, particularly intravenous antibiotics.[8][9] Recognised authorities advise against long-term antibiotic treatment for Lyme disease, even where some symptoms persist post-treatment.[4][5][6] Following disciplinary proceedings by state medical licensing boards in the United States, a subculture of "Lyme literate" physicians has successfully lobbied for specific legal protections, exempting them from the standard of care and Infectious Diseases Society of America treatment guidelines. This political interference in medical care[13][14] has been criticised as an example of "legislative alchemy", the process whereby pseudomedicine is legislated into practice.[15]
