This medication can reduce sweating, making you prone to heat stroke. Avoid activities that might cause you to overheat (e.g., doing strenuous work or exercising in hot weather; using hot tubs). Alcohol use may add to the dizziness and drowsiness effect of this drug. Use with caution in the elderly. This medication should be used only when clearly needed during pregnancy.
