The interaction between coffee and these medications could significantly impact patient care. This underscores the importance of discussing dietary habits with our patients when prescribing these medications. It also highlights a potential paradigm shift in how we approach patient education about medication use.

Key Points

1. Ephedrine: Combining ephedrine, a stimulant used in decongestants, with coffee can lead to serious health risks such as high blood pressure, heart attacks, stroke, or seizures.
2. Antidiabetic Drugs: Coffee can increase blood sugar in some individuals, which may counteract the effects of antidiabetic drugs like glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
3. Theophylline: Combining theophylline, used to treat asthma and other respiratory diseases, with coffee can increase the effects of the drug and its side effects.
4. Phenothiazines: The tannins present in coffee can bind to phenothiazines, medications used to treat mental disorders, and stop the body from absorbing them as effectively.
5. Anticoagulants: Anticoagulant drugs like aspirin, clopidogrel (Plavix), ibuprofen (Advil, Motrin, and others), naproxen (Anaprox, Naprosyn, and others), enoxaparin (Lovenox), and others can interact with coffee. This combination can slow blood clotting and increase the chances of excessive bleeding and bruising.
6. Tricyclic Antidepressants: Tricyclic antidepressants like amitriptyline (Elavil) and imipramine (Tofranil, Janimine) can have their absorption limited by the tannins present in coffee. It’s advised to avoid coffee within 1-2 hours of taking these medications.
7. Asthma Medications: Beta-adrenergic agonists used to treat asthma can have their side effects worsened when consumed with coffee. These side effects include anxiety, tremor, heart palpitations, or increased heart rate.
8. Contraceptive Drugs: Birth control drugs like ethinyl estradiol and levonorgestrel, norethindrone, and others can interact with coffee. This interaction can result in jitteriness, headaches, fast heartbeat, and other side effects.

According to a study by the National Coffee Association, 64% of Americans drink coffee every day.

In addition to these interactions with medications, coffee can also interact with vitamin supplements. Despite these potential interactions, coffee in moderation has been linked to improved cognitive performance, fat-burning qualities, post-exercise recovery, decreased risk of Parkinson’s and Alzheimer’s diseases, and even a reduced risk of chronic liver disease.
