Butalbital 50mg, Aspirin 325mg, Caffeine 40mg, Oral capsule

Alcohol

· Severity: Major

· Notes for Consumers: Do not drink alcohol while taking this medication. Drinking alcohol while taking this medication increases the risk of stomach bleeding. Contact your care team right away if you experience bloody or black, tar-like stools, vomiting blood or brown material that looks like coffee grounds.

· Notes for Professionals: Concomitant ingestion of alcohol with salicylates, especially aspirin, ASA, increases the risk of developing gastric irritation and GI mucosal bleeding. Alcohol and salicylates are mucosal irritants and aspirin decreases platelet aggregation. Routine ingestion of alcohol and aspirin can cause significant GI bleeding, which may or may not be overt. Even occasional concomitant use of salicylates and alcohol should be avoided. Chronic ingestion of alcohol is often associated with hypoprothrombinemia and this condition increases the risk of salicylate-induced bleeding. Patients should be warned regarding the potential for increased risk of GI bleeding if alcohol-containing beverages are taken concurrently with salicylates.

Caffeine-containing Foods/Beverages

· Severity: Moderate

· Notes for Consumers: Caffeine may cause sleeplessness, so if you are taking a Barbiturate to help you sleep, you may wish to avoid taking caffeine and caffeine-containing foods like colas, coffee, teas, or chocolates within several hours prior to bedtime. Barbiturates may also decrease the actions of Caffeine; if you have a high intake of caffeinated foods or beverages you may experience a headache or irritability from decreased caffeine levels while taking these drugs until your body adjusts. If you take Caffeine for other purposes, notify your health care provider if you think Caffeine is not working as well for you.

· Notes for Professionals: Caffeine has been reported to increase the metabolism of barbiturates, and barbiturates increase caffeine elimination. Higher caffeine doses may be needed after barbiturate administration.

Cannabis

· Severity: Major

· Notes for Consumers: Discuss cannabis use with your care team. The effects of cannabis may be altered if used with your medication. Call emergency services right away if you experience slow or shallow breathing, shortness of breath, feeling faint, dizziness, confusion, or trouble staying awake.

· Notes for Professionals: Advise patients to avoid cannabis use during barbiturate treatment due to the risk for additive CNS depression and other adverse reactions. Concomitant use may also decrease the concentration of some cannabinoids and alter their effects. The cannabinoids delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are CYP3A substrates and barbiturates are strong CYP3A inducers. Concomitant use of a cannabinoid product containing THC and CBD at an approximate 1:1 ratio with another strong CYP3A inducer decreased THC, 11-OH-THC, and CBD peak exposures by 36%, 87%, and 52% respectively.

Grapefruit juice

· Severity: Mild

· Notes for Consumers: Do not significantly alter your grapefruit juice intake while taking medicines containing caffeine. Some reports suggest that intake of grapefruit juice can increase side effects from caffeine. Too much Caffeine can cause effects like nausea, tremor, nervousness, or sleeplessness. If these occur, consider ingesting less caffeine daily.

· Notes for Professionals: Data are limited and conflicting as to whether grapefruit juice significantly alters the serum concentrations and/or AUC of caffeine. Caffeine is primarily a CYP1A2 substrate, and grapefruit juice appears to have but a small effect on this enzyme in vivo. One report suggests that grapefruit juice decreases caffeine elimination by inhibition of flavin-containing monooxygenase, a P450 independent system. This interaction might increase caffeine levels and mildly potentiate the clinical effects and common side effects of caffeine. If side effects appear, patients may need to limit either caffeine or grapefruit juice intake.

Tobacco

· Severity: Major

· Notes for Consumers: Do not smoke or use tobacco products while taking this medication. When used together, your medication may not work as well for you.

· Notes for Professionals: Advise patients who are taking caffeine to avoid smoking tobacco. Smoking tobacco has been observed to increase caffeine clearance by 50% to 70%. Caffeine is a CYP1A2 substrate and smoking tobacco induces CYP1A2.
