Can I drink tea after receiving an injection?

In general, whether or not one can drink tea after receiving an injection mainly depends on the type of medication being administered. If there is a potential interaction between the medication and tea, drinking tea usually is not recommended. However, if there is no known interaction between the medication and tea, moderate tea consumption may be acceptable.

Tea contains components such as polyphenols and tannic acid, which might interact with medications, affecting their absorption, metabolism, and excretion, thereby weakening or enhancing the drug's effects, or even causing adverse reactions. Therefore, during injection therapy, if the patient is taking medications that may affect drug metabolism or have specific administration requirements, it is best to avoid drinking tea to prevent unnecessary risks.

If the injected medication does not have a significant interaction with tea components, moderate tea consumption generally is considered safe. Antioxidants in green tea, such as catechins, may even provide health benefits. However, strong tea should be avoided because its high caffeine and polyphenol content may stimulate the central nervous system, causing symptoms such as palpitations and insomnia.

In daily life, it is advisable to maintain good habits and a balanced diet to promote recovery and overall health.
