Avoid alcohol-containing drinks while taking medicines that cause drowsiness. Using some of these drugs along with alcohol can lead to serious side effects. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery if you are drinking alcohol-containing beverages. If you notice slurred speech, confusion, severe weakness, or difficulty breathing, contact your health care provider immediately.

Side effects from Salicylates (such as Aspirin, ASA, Doan's Pills, Trilisate, or Disalcid) may get worse if you drink alcohol-containing drinks. If you have persistent stomach upset, vomit blood or what looks like coffee grounds, or have black, tarry stools, contact your health care provider immediately. Avoid alcohol containing drinks while taking aspirin. Alcohol intake should be limited even with short term use of Salicylates.

If you are a tobacco smoker, use of Acetaminophen can increase the risk of liver side effects. Immediately tell your doctor if you get severe abdominal pain, nausea, vomiting, or yellowing of the skin. Do not exceed 4 g acetaminophen/day in adults. Tell your doctor if Acetaminophen does not help your headache or other pain. Tobacco smoke may reduce the effectiveness of Acetaminophen.

Side effects from Caffeine may get worse if you take Grapefruit juice or other foods that contain significant amounts of Grapefruit. Too much Caffeine can cause effects like nausea, nervousness, or sleeplessness. Do not significantly alter your grapefruit juice intake while taking medicines containing caffeine.

Tobacco smoke contains substances that may speed the removal of Caffeine from the body. If you start smoking Caffeine may become less effective. Tobacco smokers often drink several caffeinated beverages daily. Just the opposite occurs when someone stops smoking tobacco; if you stop smoking this may increase the amount of Caffeine in the blood and side effects from Caffeine may get worse. Too much Caffeine can cause nausea, nervousness, or sleeplessness, and occasionally other effects like tremor. If you stop smoking tobacco, you may need to lower your Caffeine intake.

While taking Caffeine products, limit the use of foods, beverages, herbs and other medicines that contain additional caffeine, like coffee, teas, colas, chocolate and some diet pills. Too much Caffeine can cause effects like nausea, nervousness, or sleeplessness. Some drug products for adults that contain caffeine have about as much caffeine as a cup of coffee.
