For many people, coffee has become a part of their daily routine. Its strong aroma and taste serve as a welcoming wake-up call and the caffeine in it helps keep you alert for the rest of the day.
Since caffeine is a stimulant that promotes alertness, it’s not a good idea to combine coffee with drugs that contain a stimulant effect, such as Adderall, asthma medicines and bronchodilators, as taking them together can enhance their effects.
Studies also show that coffee could interfere with the absorption of certain drugs like antidepressants, thyroid medication and osteoporosis drugs. For example, a 1995 study found that taking the osteoporosis drug alendronate (Fosamax) with black coffee or orange juice reduced its absorption by about 60 percent.
Caffeine can produce an increase in intestinal movement. It may also induce an increase in the amount of fluid that flows from your body into your intestines, which results in loose stools. Both of these can make your oral medication pass through your intestines rapidly. In fact, some of the medication may leave your body in the stool before it has a chance to become absorbed into your system.
With lower absorption, the medicine is likely less effective, which increases your risk of having symptoms of hypothyroidism. On other hand, taking medicine with coffee can increase your heart rate and making you feel jittery.
How long should I wait to drink coffee after taking medicine?
Health experts advise people to wait around two to three hours after taking medication if you want to consume coffee or other caffeine-containing products.
Be sure to check with your doctor or pharmacist about whether there might be interactions between caffeine and any medication that you take. And it’s better to ask your doctor or pharmacist about the details of the safe time to drink coffee before or after taking the medication.
