Estrogens, Synthetic Conjugated
What It's For & How To Take
Synthetic conjugated estrogens are an oral tablet used to treat full body symptoms that happen due to a lowering of estrogen during menopause. These symptoms may include hot flashes, mood swings, and vaginal dryness. This medication may also be used to treat women who are not able to produce estrogen.
This medication is also used to help prevent bone loss in women after menopause; however, if bone loss is the only symptom, other medications are safer to take and are just as effective at maintaining bone strength.
Synthetic conjugated estrogens are used to treat vaginal symptoms such as dryness, burning, and itching. If these are the only symptoms you are treating, talk with your doctor about a medication that is taken directly into the vagina rather than a tablet you swallow.
This medication is usually taken once daily, with or without food. Take this medication at the same time each day. If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
Most Important Warnings
- There is an increased risk of cancer in the uterus in women who use estrogen without also taking a progestin. Call your doctor right away at the first sign of genital bleeding.
- Estrogen therapy given by itself has been linked to an increased risk of stroke and blood clots in the legs.
- Estrogen therapy used along with progestin treatment has been linked to an increased risk of heart attack, stroke, blood clots in the legs or lungs, and increased risk of breast cancer.
- Estrogen therapy, with or without progestin, has been shown to increase the chances of heart disease and dementia and should not be used for the treatment of either of these two disease states
- Estrogen, with or without progestin, should be prescribed at the lowest effective dose for the shortest duration of therapy, specific for each patient. Ask your doctor to evaluate your conjugated estrogens dose every 6 months to see if your dose may be lowered.
