Why this interaction occurs
Research has shown bromelain can enhance tissue penetration and serum levels of tetracycline through its proteolytic action on mucosal barriers and its ability to modulate drug transport. This can lead to supratherapeutic antibiotic concentrations and increased adverse effect risk.
Evidence
Evidence level: moderate.
