Anastrozole is a medication that is commonly prescribed to women with breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by blocking the production of estrogen in the body. While anastrozole is generally safe and effective, there are certain foods that can interfere with its effectiveness or cause side effects.
Foods To Avoid When Taking Anastrozole
Here are some foods to avoid when taking anastrozole:
Alcohol
Alcohol can interact with anastrozole and increase the risk of side effects, such as dizziness, drowsiness, and nausea. It’s best to avoid alcohol altogether while taking anastrozole, or at least limit your intake to small amounts.
Grapefruit and grapefruit juice
Grapefruit and grapefruit juice contain compounds that can interfere with the way anastrozole is metabolized in the body. This can increase the levels of the medication in the blood and increase the risk of side effects. It’s best to avoid grapefruit and grapefruit juice while taking anastrozole.
High-fat foods
Consuming high-fat foods while taking anastrozole can cause the medication to be less effective. This is because fat slows down the absorption of anastrozole in the body, which can prevent it from working as well. Avoid eating high-fat foods like fried foods, fatty meats, and full-fat dairy products while taking anastrozole.
Certain herbs and supplements
Some herbs and supplements, such as St. John’s wort, can interfere with the way anastrozole is metabolized in the body. This can reduce the effectiveness of the medication and increase the risk of side effects. It’s important to talk to your doctor before taking any herbs or supplements while taking anastrozole.
Caffeine
Caffeine can interact with anastrozole and increase the risk of side effects, such as dizziness, drowsiness, and nausea. It’s best to avoid or limit caffeine-containing foods and beverages, such as coffee, tea, and energy drinks, while taking anastrozole.
Overall, while taking anastrozole it’s important to follow a healthy and balanced diet and avoid foods that can interfere with the medication’s effectiveness or cause side effects. Talk to your doctor or a registered dietitian for personalized advice on what foods to avoid while taking anastrozole.
