6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The most common adverse reaction is transient drowsiness.
In one controlled study of 175 patients, transient drowsiness was observed in 63% of those receiving baclofen compared to 36% of those in the placebo group.
Other common adverse reactions (up to 15%) are dizziness and weakness.
Adverse reactions with a frequency of ≥1% are listed in Table 1.
