Many of us believe that coffee has a very specific benefit: giving us a much-needed boost of energy in the morning. But studies show there are plenty of reasons to embrace a daily cup (or more) of Joe. Drinking two cups a day has been shown to reduce the risk of liver cancer, and coffee may even help people live longer and reduce their risk of heart disease.
Then, of course, there are the well-known negatives of coffee: it’s addictive, it can upset your stomach, and “drinking coffee can also lead to a drop in stimulants later in the day; such as a loss of energy, the need for a nap, and loss of motivation”, warns Wendi D.Jones, PharmD, MSPS. “This is often the reason why coffee drinkers tend to be tired by mid-afternoon.”
A lesser-known downside of coffee? If you use it to wash off certain medications, it may have a negative impact on your health. Read on to find out which drugs you should never take with your morning coffee.

Taking antidepressants with coffee can backfire on you in two ways. “Coffee can interact with tricyclic antidepressants (TCAs) potentially leading to reduced absorption of the drug, which would prevent the patient from receiving the full prescribed dose,” warns Jones. In addition, fluvoxamine SSRI “is also known to enhance the effects of caffeine, so people who drink large amounts of caffeine may experience unpleasant symptoms such as heart palpitations, nausea, restlessness and insomnia,” says the National Health Service.
It is best not to combine coffee with stimulants such as Adderall. “While small amounts of coffee may not make Adderall side effects worse, the combination of the two may increase the risk of side effects such as high blood pressure, rapid heartbeat, jitters and moodiness. sleep,” according to GoodRx.
“Coffee, a stimulant, also interacts with other stimulants and could lead to increased heart rate and increased risk of tachycardia,” Jones says, noting that two other examples of stimulants include pseudoephedrine and epinephrine.

Vitamins won’t do much if their properties are pushed too quickly through your digestive system or flushed out of your body before they can have any positive effect. “Coffee is a diuretic and can lead to the loss of water-soluble vitamins such as vitamin B and vitamin C when taken together,” Jones warns. And caffeine will speed up the digestion process by “increasing the contractions that force food through your digestive tract,” according to LiveStrong, whose experts also point out that coffee can limit or reduce your absorption of iron and calcium.

You may not think that coffee has a negative effect on diabetes medications. But in fact, “coffee may raise blood sugar levels in some individuals, which is likely to counteract the effects of diabetes medications, MDlinx warns. “Diabetes patients who like to drink coffee should have their blood sugar levels carefully monitored and may need ‘have their drug dosage changed to account for these effects.’
A 2008 study published by the National Library of Medicine found that coffee interfered with the thyroid drug levothyroxine. VerywellHealth explains how caffeine affects how levothyroxine is absorbed by the body: “Caffeine is a stimulant that can increase intestinal motility, the muscle contractions that move food through the digestive tract,” the site explains. “Caffeine also has a mild laxative effect and increases the amount of fluid in the stool.”
Both of these things can cause the drug to move too quickly through the intestines, hindering absorption. “When this happens, your thyroid hormone levels can drop and lead to symptoms of hypothyroidism, including fatigue, muscle weakness, weight gain, hoarseness, and sensitivity to cold,” their experts warn.
