One of the main complaints is the bulkiness of the tablets. The main offender is PZA (the tablets being the size of horse tablets). PZA syrup may be offered as a substitute, or if the size of the tablets is truly an issue and liquid preparations are not available, then PZA can be omitted altogether. If PZA is omitted, the patient should be warned that this results in a significant increase in the duration of treatment (details of regimens omitting PZA are given below).
