Drinking green tea has become a daily habit for many Portuguese, appreciated for the taste and potential health benefits. However, this infusion may interact with certain medications, altering its effectiveness and, in some cases, causing unwanted effects.
Why green tea can interfere with medicines
Green tea contains bioactive compounds such as caffeine and polyphenols, which can alter the way some drugs are absorbed or metabolized by the body. These interactions may reduce the effectiveness of the drug or increase the risk of adverse effects.
The consequences depend on the dose of drink, the type of medicine and the frequency of consumption. Eatingwell, specializing in nutrition and well-being, warns that even minor food routine changes can influence the effect of certain drugs.
Anticoagulants and Vitamin K: Drive Attention
Anticoagulants require special care when combined with green tea. They may be less effective when ingested along with large amounts of the drink, due to the presence of vitamin K, albeit in amounts lower than those found in green leafy vegetables.
Sudden changes in vitamin K intake may reduce the effectiveness of varfarin and increase the risk of coagulation. Therefore, it is important that those who use this type of medicine maintain a consistent diet and always consult the doctor before increasing the consumption of green tea.
Effects on stimulants and mental health
Stimulating medications, often used in treating the attention deficit and hyperactivity, may have the effects enhanced by green tea. Infusion caffeine, although in less than coffee, can increase heart rate, blood pressure and cause anxiety or insomnia.
For drugs used in mental health, caffeine can compete for the metabolism of the drug, raising the levels of the substance in the body and increasing the risk of adverse effects. These effects include sedation, changes in blood pressure or seizures, depending on the type of drug and individual sensitivity.
Iron supplements and mineral absorption
Certain compounds present in green tea may interfere with iron absorption, potentially increasing the risk of anemia. However, the results of the investigations are still inconclusive, so experts recommend attention and medical follow -up.
Those who take iron supplements should evaluate the consumer time in relation to green tea. Separating drink and supplement intake can minimize possible interference and optimize mineral absorption.
Coffee: Care similar to those of green tea
In addition to tea, coffee consumption also requires precaution when it is medicated. Some medications may have their absorption reduced or interference when combined with caffeine.
Among the affected drugs are those used to treat thyroid diseases, diabetes, Alzheimer’s, Asthma, Osteoporosis, Depression and Hypertension. For drugs for constipation or allergies, coffee can aggravate symptoms and make sleep difficult, making medical follow -up essential.
Moderation and medical follow -up are essential
The habit of drinking green tea or coffee is not prohibited, but moderation and medical follow -up are critical to avoiding complications. Informing the healthcare professional about daily consumption habits helps to reduce risks and adjust treatment whenever necessary.
The interaction between infusions and medicines shows the importance of knowing the effects of the substances we eat. As you refer, maintaining attention to diet and consumption habits is crucial to ensuring that drugs comply with the expected effect without unwanted effects.
