Use caution when driving, operating machinery, or performing other hazardous activities. Dichloralphenazone may cause drowsiness or dizziness. If you experience drowsiness or dizziness, avoid these activities.
Avoid alcohol. Alcohol taken during therapy with acetaminophen, dichloralphenazone, and isometheptene can be very damaging to your liver and can increase drowsiness and dizziness.
Never take more acetaminophen, dichloralphenazone, and isometheptene than is prescribed for you. If your pain is not being adequately treated, talk to your doctor.
Avoid other over-the-counter and prescription products that contain acetaminophen. Too much acetaminophen could be dangerous. Talk to your doctor or pharmacist before taking any over-the-counter preparations.
