Coffee and medicine: what you need to know

Coffee is the most widely consumed psychoactive substance in the world, and its interactions with medicines can be complex and unpredictable. As a coffee lover, it’s essential to be aware of how your daily cup may impact your ability to take certain medications safely and effectively.

The good, the bad, and the complex

On the one hand, coffee can have a positive impact on certain medications. For example, studies have shown that caffeine can improve the bioavailability of paracetamol (acetaminophen), making it more effective for pain relief. Additionally, coffee has been found to enhance the absorption of some medications, such as fexofenadine (Allegra), which can improve its effectiveness at reducing allergy symptoms.

On the other hand, coffee can also interfere with the action of certain medications. Caffeine can increase the heart rate and blood pressure, which may interact with medications used to treat conditions such as hypertension, angina, and arrhythmias. Furthermore, coffee can decrease the absorption of certain nutrients, including iron, which can exacerbate conditions such as anemia.

The big three to watch

There are three medications in particular that coffee lovers should be aware of when it comes to interactions:

  1. Warfarin (Coumadin): Caffeine can increase the metabolism of warfarin, which may lead to a decrease in its effectiveness. Patients taking warfarin should limit their coffee intake or avoid it altogether.
  2. Medications for migraines: Caffeine can exacerbate migraines and interact with medications such as triptans (e.g., sumatriptan, naratriptan) and ergotamines (e.g., ergotamine). Patients taking these medications should limit their coffee intake or avoid it altogether.
  3. Theophylline: Caffeine can increase the levels of theophylline in the blood, which can lead to an increased risk of side effects such as nausea, vomiting, and headaches. Patients taking theophylline should limit their coffee intake or avoid it altogether.

The bottom line

While coffee can be a safe and enjoyable part of a healthy lifestyle, it’s essential to be aware of its potential interactions with medications. If you’re taking any prescription medications, it’s always a good idea to consult with your doctor or pharmacist about safe coffee consumption guidelines. By being mindful of these interactions, you can enjoy your coffee while

How coffee influences cognitive performance

For many of us, the day doesn’t truly begin until we have had our first cup of coffee. This beloved beverage has become an integral part of our daily routine and culture. But beyond its invigorating effects and delightful taste, research suggests that coffee might hold the key to enhancing cognitive performance in various aspects of life. Let’s dive into the fascinating relationship between coffee consumption and brain power!

Caffeine as a stimulant

The primary active ingredient in coffee is caffeine, a natural stimulant that blocks adenosine receptors in the brain. Adenosine promotes sleep and relaxation; thus, when blocked by caffeine, we experience increased alertness and concentration (Nehlig, 2010). Moreover, caffeine can cross the blood-brain barrier quickly, reaching peak concentrations within 30-60 minutes after ingestion, allowing for swift improvements in mental clarity.

Improved working memory

Studies reveal that moderate doses of caffeine – approximately 200 mg or two cups of brewed coffee – consumed before engaging in cognitively demanding tasks can enhance working memory capacity (Hindmarch et al., 2000). Working memory refers to the ability to temporarily store and manipulate information required for complex thinking, learning, and problem-solving. By increasing neural activity in regions associated with attention and executive functions, coffee helps fuel optimal cognitive performance.

Mood enhancement

Drinking coffee not only boosts energy levels but also elevates mood due to the release of dopamine, a neurotransmitter linked to pleasure and reward systems in the brain (Fisone et al., 2004). Consequently, this feel-good factor contributes to improved focus and motivation, further supporting enhanced cognitive abilities. However, it is essential to consume coffee in moderation since excessive intake may lead to restlessness, anxiety, and other negative side effects.

Protection against neurodegenerative diseases

Emerging evidence indicates that long-term coffee consumption could offer protective benefits against age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease (Liu et al., 2016). Regular coffee drinkers exhibit lower risks of developing these conditions, possibly attributed to the antioxidants present in coffee beans which help reduce inflammation and oxidative stress in the brain.

Tips for optimizing coffee consumption

To maximize the cognitive benefits of coffee while minimizing potential drawbacks, consider implementing the following strategies:

  1. Time your intake wisely: To avoid interfering with nighttime sleep quality, refrain from consuming coffee at least six hours before bedtime.
  2. Monitor your tolerance: Individual responses to caffeine vary significantly; pay attention to how your body reacts and adjust accordingly.
  3. Choose high-quality options: Opt for freshly roasted, specialty-grade coffee beans prepared using methods that preserve their flavor profile and nutritional content.
  4. Stay hydrated: Drink plenty of water throughout the day to prevent dehydration caused by caffeine consumption.
  5. Balance your diet: Ensure you maintain a well-rounded eating pattern rich in fruits, vegetables, lean proteins, and whole grains to support overall brain health.


Incorporating coffee into your daily routine can provide more than just a morning pick-me-up; it can potentially unlock doors to heightened cognitive performance. From bolstering working memory and mood enhancement to offering protection against neurodegenerative disorders, the humble cup of joe proves itself a valuable asset in promoting mental acuity and longevity. So go ahead, savor each sip knowing you are nourishing both body and mind!

Perk up your day: 6 compelling reasons to drink coffee

Coffee, the aromatic elixir enjoyed by millions of people around the world every day, is much more than a just a beverage. There are so many reasons to drink coffee. Beyond its delicious taste and enticing aroma, coffee offers a myriad of benefits that can enhance our lives in many ways. Whether you enjoy a cup of java to kick-start your morning or find solace in its comforting embrace during a busy day, here are six compelling reasons why you should embrace coffee as a delightful companion.

Mood booster and stress reliever

Have you ever noticed how a simple whiff of freshly brewed coffee can instantly lift your spirits? Coffee has been linked to improved mood and a reduction of symptoms of depression. It stimulates the production of dopamine and serotonin—neurotransmitters responsible for feelings of happiness and well-being. In addition, taking a break to enjoy a warm cup of coffee can provide a brief respite from the stresses of daily life, giving you a moment of relaxation and calm.

Improve physical performance

For fitness enthusiasts and athletes, there is another reason to drink coffee. It can be a secret weapon for improving performance. The caffeine in coffee stimulates the nervous system, signaling the release of adrenaline, which can improve physical performance and endurance. By reducing perceived exertion and increasing fat oxidation, coffee can help you push your limits during excercises and maximize your workout.

Social connection and bonding

Discovering different brewing methods, exploring new roasts, or even experimenting with latte art can be a delightful journey of sensory pleasure. With coffee, you can awaken your taste buds and embark on a never-ending adventure of flavors and aromas.


Beyond its enticing taste and comforting warmth, coffee offers a range of benefits that can enrich your life. From providing an energy boost to improving focus, enhancing mood, boosting physical performance, and facilitating social connections, coffee has become an integral part of our daily rituals. So, the next time you’re enjoying that perfect cup of coffee and savoring in its unique flavors, remember that you’re not just enjoying a beverage; you’re indulging in a delightful experience that offers a multitude of benefits.

While coffee can be a wonderful addition to your daily routine, excessive consumption may lead to negative effects such as sleep disturbances or increased anxiety. It’s important to listen to your body and find the balance that works best for you.

So, whether you’re a coffee aficionado or someone who is just beginning to appreciate its wonders, embrace the joy that comes with each sip.
