What are the side effects of Premarin?

There is a long list of side effects for women who take Premarin, which is a form of conjugated estrogens. No one will have them all and some will have just a few. The most common side effects of taking conjugated estrogens are vaginal bleeding, vaginitis, yeast infection, headache, period cramps, breast swelling, breast pain and leg cramps. But there are some serious long-term effects you should talk about in detail with your doctor before you take it. Some of the more serious complications include blood clots in the legs (deep vein thrombosis), lungs (pulmonary embolism), heart (heart attack) or brain (stroke). It can also increase the risk for breast cancer.

As with all medicine you are taking, make a point to ask your pharmacist for the package insert. You may need a magnifying glass to read it, but most of the side effects will be listed there. If you have any new symptoms and you aren't sure if it is caused by the medicine you are taking, don’t hesitate to ask your doctor or pharmacist.

Premarin may have several side effects, some serious and some not so serious. Serious side effects can include chest pain, numbness or weakness, vision problems, unusual vaginal bleeding, high blood pressure, migraine headaches, jaundice, swelling, breast lump, and stomach pain. Other side effects may include nausea or vomiting, breast tenderness, hair loss or growth, vaginal itching, lessened sex drive, changes in menstrual cycle, fatigue, change in weight, headaches, and dizziness. These are only some of the possible side effects. If you are prescribed Premarin, you should talk with your doctor about all of the possible side effects, and always contact your doctor immediately if you experience any of these symptoms.
