Accidentally taking an extra dose of Anastrozole can be concerning. This guide provides clear information on what Anastrozole is, what steps to take if an error occurs, and how to prevent future mistakes.
What Anastrozole Is
Anastrozole is a medication primarily used to treat hormone receptor-positive breast cancer in postmenopausal women. It is an aromatase inhibitor that works by blocking the enzyme aromatase, which converts other hormones into estrogen. By reducing estrogen levels, Anastrozole helps slow or stop the growth of breast cancer cells that depend on estrogen. It is typically prescribed as a 1 mg tablet taken once daily.
What to Do Immediately
If you have taken two Anastrozole tablets, do not take any more doses until you have spoken with a healthcare professional. While a single extra dose is often unlikely to cause severe or lasting harm, professional guidance is advisable. Contact your doctor or pharmacist as soon as possible for personalized advice. They can assess your situation and provide tailored instructions. If you are unable to reach your healthcare provider, call a poison control helpline for immediate guidance.
Monitoring for Effects and When to Call for Help
Taking a higher dose of Anastrozole might increase common, typically mild, side effects. These can include hot flashes, nausea, vomiting, headache, joint pain, muscle stiffness, or fatigue. These effects are usually mild and may improve as your body adjusts. If you experience them, continue to monitor your symptoms and communicate with your healthcare provider.
While a double dose is often not severe, certain symptoms warrant immediate medical attention. Seek emergency medical help if you experience severe symptoms such as sudden chest pain, shortness of breath, or severe allergic reactions like hives, difficulty breathing, or swelling of the face or throat. Other serious signs include severe stomach pain, yellowing of the skin or eyes (indicating liver problems), or stroke symptoms like sudden numbness or weakness on one side of the body. If any severe symptoms occur, call emergency services or go to the nearest emergency room, bringing the medication packaging with you.
Tips for Avoiding Future Dosing Errors
Implementing strategies can help prevent future medication dosing errors. Using a pill organizer can clearly separate daily doses and help confirm whether a dose has been taken. Setting a daily reminder on a phone or alarm clock, or keeping medication in a consistent, visible location, can help establish a routine and reduce the chance of forgetting or double-dosing. Always check the label before taking any medication to confirm it is the correct drug and dosage. Marking off each dose on a calendar or in a logbook immediately after taking it can also be helpful.
