The most common adverse reactions reported with CAMBIA (diclofenac potassium for oral solution) are nausea and dizziness.
The most common adverse events resulting in discontinuation of patients following CAMBIA (diclofenac potassium for oral solution) dosing in controlled clinical trials were urticaria (0.2%) and flushing (0.2%).
Clinical Studies Experience with CAMBIA (diclofenac potassium for oral solution)
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of a single dose of CAMBIA (diclofenac potassium for oral solution) was evaluated in 2 placebo-controlled trials with a total of 634 migraine patients treated with CAMBIA (diclofenac potassium for oral solution) for a single migraine headache. Following treatment with diclofenac potassium (either CAMBIA or diclofenac potassium immediate-release tablets [as a control]), 5 subjects (0.8%) withdrew from the studies; following placebo exposure, 1 subject (0.2%) withdrew. No withdrawals were due to a serious reaction.
The most common adverse reactions (i.e., that occurred in 1% or more of CAMBIA (diclofenac potassium for oral solution) -treated patients) and more frequent with CAMBIA (diclofenac potassium for oral solution) than with placebo were nausea and dizziness (see Table 1).
