Altamofen is nonsteroidal anti-estrogen tablet containing Tamoxifen Citrate, which basically functions as an anti-cancer drug. Tamoxifen Citrate blocks the biological effects of the female estrogen hormone on the development of breast cancer.

Altamofen is prescribed as oral therapy in women as well as men who have developed breast tumors which are dependent on estrogen for their growth and survival in the body. Altamofen tablets are also recommended as treatment in women who have a higher risk of developing breast cancer to effectively lower the possibility of contracting breast cancer. Altamofen tablets are suggested as anti-cancer treatment after the completion of surgery, radiation, and chemotherapy to prevent the metastasis of the cancer cells to the other parts of the body and also to lower the chances of the recurrence of tumors.

You should use Altamofen exactly as recommended by your doctor. Your doctor may suggest a dosage of Altamofen depending whether Altamofen is used for the treatment or prevention of breast cancer, the stage of cancer, body weight, other medical conditions, and current medications. Altamofen should be taken once or twice a day with a glass of water, after a meal to avoid indigestion problems. Try to maintain a regular schedule for the medication such that you take Altamofen tablets at the same time every day, to get the maximum benefit of the medication. Doctors usually recommend a dosage of a single Altamofen once daily after a meal.

If you miss your regular dose of Altamofen, take it as soon as you remember. You can continue your regular schedule the next day. If you remember the missed Altamofen the next day, take your regular dose and skip the missed dose. Do not take a double dose to compensate the missed dose of Altamofen.
