Moxifen 20 mg Tablet

Moxifen 20 mg Tablet is a prescription anti-cancer medicine containing tamoxifen 20 mg in each tablet. One strip/box contains 10 packs, and each tablet is designed for oral use under medical supervision. It belongs to the selective estrogen receptor modulator (SERM) class and is commonly used to treat and help prevent certain estrogen receptor-positive breast cancers. Moxifen 20 mg Tablet may also be used in other situations your oncologist or prescriber determines are appropriate.

How it works: Tamoxifen in Moxifen 20 mg Tablet works by blocking estrogen from attaching to receptors in breast tissue, which can slow or stop the growth of hormone-sensitive cancer cells. The tablet form gives a measured oral dose that is absorbed after swallowing, so the medicine can work systemically throughout the body.

Moxifen 20 mg Tablet is a higher-strength option than Moxifen 10 mg Tablet, so it is generally chosen for people whose doctor wants a 20 mg dose rather than a lower-strength tablet. This can reduce the need to take multiple 10 mg tablets to reach the prescribed daily amount, but it is not meant for self-adjusting the dose or for starting treatment without medical direction.

• Treatment of estrogen receptor-positive breast cancer
• Reduction of recurrence risk after breast cancer treatment
• Lowering risk of breast cancer in selected high-risk patients
• Management of certain hormone-sensitive breast conditions as prescribed

• Swallow Moxifen 20 mg Tablet whole with a glass of water.
• Take it at the same time each day to help you remember.
• You may take it with or without food if your doctor does not advise otherwise.
• Do not crush, chew, or split the tablet unless your prescriber tells you to.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.
• Follow your oncologist’s exact schedule, since the 20 mg strength may be part of a specific treatment plan.

Each Moxifen 20 mg Tablet provides 20 mg of tamoxifen per tablet, so the amount of medicine in each dose is fixed by this strength. Depending on the condition being treated, a doctor may prescribe 20 mg once daily or a different schedule; the maximum daily dose should be determined by the prescriber and should not be changed on your own.

Do not change your dose or stop the medicine without speaking to your doctor.
