Tamoxifen Dosage: Simple Guide for Patients
Tamoxifen is a common drug used to treat and prevent breast cancer. If you or someone you know is starting it, the biggest question is usually: how much should I take? This guide gives you the basics – the usual dose, why doctors might change it, and practical tips to stay safe.
Usual Dosage for Breast Cancer Treatment
For most women with estrogen‑receptor‑positive breast cancer, the standard dose is 20 mg once a day. The pill is usually taken at the same time each day, with or without food – whatever fits your routine.
If tamoxifen is prescribed to lower the risk of cancer (for example, after surgery or for women with a high genetic risk), doctors sometimes start with 10 mg daily. The lower dose still blocks estrogen enough to keep cells from growing, but it can have fewer side effects for some people.
When the drug is used for other conditions, like certain fertility issues, the dose can be higher – up to 30 mg per day split into two doses. Your doctor will explain why a higher amount is needed and will monitor you closely.
Things That Can Change Your Dose
Not everyone stays on the same dose for the whole treatment. Here are the most common reasons doctors might adjust it:
- Liver function: Tamoxifen is processed by the liver. If blood tests show liver problems, the dose may be reduced or the drug paused.
- Age and weight: Older patients or those with very low body weight sometimes need a lower dose to avoid extra side effects.
- Drug interactions: Certain antidepressants, anti‑seizure meds, and some antibiotics can change how your body handles tamoxifen. Your doctor may tweak the dose or choose a different medicine.
- Side effects: Hot flashes, mood swings, or clotting issues are common. If they become severe, the doctor might cut the dose or add another medication to help.
Never change the dose on your own. If you miss a pill, take it as soon as you remember unless it’s almost time for the next dose – then just skip the missed one and continue the schedule.
It's also a good idea to keep a simple log: write down the time you take the pill, any new symptoms, and any other meds you start. This makes it easier for your doctor to spot patterns and adjust treatment safely.
In short, most people stick with 20 mg daily, but the exact amount can shift based on health, other drugs, and how you feel. Talk with your doctor regularly, follow the dosing schedule, and report any new issues right away. With the right dose, tamoxifen can be a powerful tool in keeping breast cancer at bay.
