The combination of enalapril and felodipine is used to treat high blood pressure. It decreases certain chemicals that tighten the blood vessels so blood flows more smoothly and the heart can pump blood more efficiently. It also relaxes your blood vessels so your heart does not have to pump as hard.This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

The combination of ergotamine and caffeine is used to prevent and treat migraine headaches. Ergotamine is in a class of medications called ergot alkaloids. It works together with caffeine by preventing blood vessels in the head from expanding and causing headaches.

Oral contraceptives (birth-control pills) are used to prevent pregnancy. Estrogen and progestin are two female sex hormones. Combinations of estrogen and progestin work by preventing the release of eggs from the ovaries (ovulation) and changing the cervical mucus and the lining of the uterus. Oral contraceptives are a very effective method of birth control, but they do not prevent the spread of AIDS and other sexually transmitted diseases.

Enoxaparin is used to prevent blood clots in the leg in patients who are on bedrest or who are having hip replacement, knee replacement, or stomach surgery. It is used in combination with aspirin to prevent complications from angina (chest pain) and heart attacks. It is also used in combination with warfarin to treat blood clots in the leg. Enoxaparin is in a class of medications called low molecular weight heparins. It works by stopping the formation of substances that cause clots.

Symptoms of allergic reaction include wheezing, shortness of breath, low blood pressure, hives, itching, swelling, stomach cramps, diarrhea, and loss of bladder control. Epinephrine is in a class of medications called sympathomimetic agents. It works by relaxing the muscles in the airways and tightening the blood vessels.

Eplerenone is used alone or in combination with other medications to treat high blood pressure. Eplerenone is in a class of medications called mineralocorticoid receptor antagonists. It works by blocking the action of aldosterone, a natural substance in the body that raises blood pressure.

Ezetimibe is used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in the blood. It may be used alone or in combination with an HMG-CoA reductase inhibitor (statin). Ezetimibe is in a class of medications called cholesterol-lowering medications. It works by preventing the absorption of cholesterol in the intestine. Buildup of cholesterol and fats along the walls of the blood vessels (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to the heart, brain, and other parts of the body. Lowering blood levels of cholesterol and fats may help to prevent heart disease, angina (chest pain), strokes, and heart attacks.

The combination of erythromycin and benzoyl peroxide is used to treat acne. Erythromycin and benzoyl peroxide are in a class of medications called topical antibiotics. The combination of erythromycin and benzoyl peroxide works by killing the bacteria that cause acne.

Emtricitabine is in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). Emtricitabine works by slowing the spread of HIV in the body. Emtricitabine does not cure HIV infection and may not prevent you from developing HIV-related illnesses. Emtricitabine does not prevent you from spreading HIV to other people.

Epinastine ophthalmic solution is used to prevent itching of the eyes caused by allergic conjunctivitis (a condition in which the eyes become itchy, swollen, red, and teary when they are exposed to certain substances in the air). Epinastine is in a class of medications called antihistamines. It works by preventing the release of natural substances which cause allergic reactions in the eyes.

Etonogestrel and ethinyl estradiol vaginal ring is used to prevent pregnancy. Etonogestrel and ethinyl estradiol vaginal ring is in a class of medications called combination hormonal contraceptives (birth control medications). Etonogestrel is a progestin and ethinyl estradiol is an estrogen. Etonogestrel and ethinyl estradiol vaginal ring works by preventing ovulation (the release of an egg from the ovaries). It also changes the lining of the uterus (womb) to prevent pregnancy from developing and changes the mucus at the cervix (opening of the uterus) to prevent sperm (male reproductive cells) from entering. The contraceptive ring is a very effective method of birth control but does not prevent the spread of human immunodeficiency virus [HIV, the virus that causes acquired immunodeficiency syndrome (AIDS)] or other sexually transmitted diseases.

Ethosuximide is used to treat a type of seizure called absence (petit mal). Ethosuximide acts on the brain and nervous system in the treatment of epilepsy.

Estradiol transdermal system is a type of estrogen used to treat symptoms associated with menopause: hot flashes (feelings of warmth in the face, neck, and chest), sweating, sleep disturbances, vaginal discomfort (dryness and itching), poor concentration, and irritability. It is also used in the treatment of female hypogonadism, female castration, primary ovarian failure, conditions caused by low amounts of estrogen such as atrophic vaginitis, and uterine bleeding caused by a hormonal imbalance.

Estradiol transdermal system is also used with diet, calcium supplements, and exercise to slow the progression of osteoporosis, a disease common in women after menopause resulting in bones that break easily.

Estradiol transdermal system may be used alone or together with a progestin taken 10 or more days each cycle.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Etidronate is used to treat Paget's disease of bone and to treat and prevent certain types of bone problems that may occur after hip replacement or spinal cord injury. Etidronate is in a class of medications called bisphosphonates. It works by preventing bone breakdown and increasing bone density (thickness).

Estrogen is a hormone, a substance produced by the body. It is needed for normal growth and development of female sex organs and for functions such as bearing children. During menopause, the body's production of estrogen is decreased. Estrogen replacement is used for symptoms associated with menopause: hot flashes (feelings of warmth in the face, neck, and chest), sweating, sleep disturbance, vaginal discomfort (dryness and itchiness), poor concentration, and irritability. It also is used in the treatment of breast cancer in postmenopausal women and breast and prostate cancer in men.

Estrogen is also used with diet, calcium supplements, and exercise to slow the progression of osteoporosis, a disease common in women after menopause resulting in bones that break easily.

Estazolam is used on a short-term basis to help you fall asleep and stay asleep through the night.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Epoetin is used to treat anemia (a lower than normal number of red blood cells in people with serious kidney disease. Epoetin is also used to treat anemia caused by certain medications, including some types of chemotherapy (medications to treat cancer) and zidovudine ( Retrovir, Trizivir, Combivir), a medication to treat human immunodeficiency virus (HIV). Epoetin is also used before and after certain types of surgery to prevent and treat anemia that may develop because of blood loss during the surgery. Epoetin is in a class of medications called erythropoiesis stimulating proteins. It works by causing the bone marrow (soft tissue inside the bones where blood is made) to make more red blood cells. This may improve your energy and activity level and may decrease your need for transfusion (transfer of another person's blood to your body)

Efavirenz is used with other medications to treat human immunodeficiency virus (HIV) infection in patients with or without acquired immunodeficiency syndrome (AIDS). Efavirenz is in a class of medications called nonnucleoside reverse transcriptase inhibitors (NNRTIs). Efavirenz works by slowing the spread of HIV in the body. Efavirenz does not cure HIV infection and may not prevent you from developing HIV-related illnesses. Efavirenz does not prevent you from spreading HIV to other people.

Estrogens ( ES-troe-jenz) are female hormones. They are produced by the body and are necessary for the normal sexual development of the female and for the regulation of the menstrual cycle during the childbearing years.

The ovaries begin to produce less estrogen after menopause (the change of life). This medicine is prescribed to make up for the lower amount of estrogen. Estrogens help relieve signs of menopause, such as hot flashes and unusual sweating, chills, faintness, or dizziness.

Estrogens are prescribed for several reasons:

• to provide additional hormone when the body does not produce enough of its own, such as during menopause or when female puberty (development of female sexual organs) does not occur on time. Other conditions include a genital skin condition (vulvar atrophy), inflammation of the vagina (atrophic vaginitis), or ovary problems (female hypogonadism or failure or removal of both ovaries).
• to help prevent weakening of bones (osteoporosis) in women past menopause.
• in the treatment of selected cases of breast cancer in men and women.
• in the treatment of cancer of the prostate in men.

Estrogens may also be used for other conditions as determined by your doctor.

There is no medical evidence to support the belief that the use of estrogens will keep the patient feeling young, keep the skin soft, or delay the appearance of wrinkles. Nor has it been proven that the use of estrogens during menopause will relieve emotional and nervous symptoms, unless these symptoms are caused by other menopausal symptoms, such as hot flashes or hot flushes.

Oral contraceptives are known also as the Pill, OCs, BCs, BC tablets, or birth control pills. This medicine usually contains two types of hormones, estrogens (ES-troh-jenz ) and progestins ( proh-JES-tins) and, when taken properly, prevents pregnancy. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization is prevented. Although oral contraceptives have other effects that help prevent a pregnancy from occurring, this is the main action.

Sometimes a woman's egg can still develop even though the medication is taken once each day, especially when more than 24 hours pass between two doses. In almost all cases when the medicine was taken properly and an egg develops, fertilization can still be stopped by oral contraceptives. This is because oral contraceptives also thicken cervical mucus at the opening of the uterus. This makes it hard for the partner's sperm to reach the egg. In addition, oral contraceptives change the uterus lining just enough so that an egg will not stop in the uterus to develop. All of these effects make it difficult to become pregnant when properly taking an oral contraceptive.

No contraceptive method is 100 percent effective. Studies show that fewer than one of each one hundred women correctly using oral contraceptives becomes pregnant during the first year of use. Birth control methods such as having surgery to become sterile or not having sex are more effective. Using condoms, diaphragms, progestin-only oral contraceptives, or spermicides is not as effective as using oral contraceptives containing estrogens and progestins. Discuss with your health care professional your options for birth control.

The triphasic cycle product of norgestimate and ethinyl estradiol (the brand name Ortho Tri-Cyclen) and norethindrone acetate and ethinyl estradiol (the brand name Estrostep ) can be used for the treatment of moderate acne only if the patient is at least 15 years old, has acne that has not improved with topical anti-acne medicines, has gotten approval from her doctor, has begun to have menstrual periods, desires an oral contraceptive for birth control, and plans to stay on it for at least 6 months.

Sometimes these preparations can be used for other conditions as determined by your doctor.

Etoposide ( e-toe-POE-side) belongs to the group of medicines known as antineoplastic agents. It is used to treat cancer of the testicles and certain types of lung cancer. It is also sometimes used to treat some other kinds of cancer in both males and females.

The exact way that etoposide acts against cancer is not known. However, it seems to interfere with the growth of the cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by etoposide, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects may not occur until months or years after the medicine is used.

Before you begin treatment with etoposide, you and your doctor should talk about the good this medicine will do as well as the risks of using it.

Epoprostenol (e-poe-PROST-en-ole) belongs to a group of agents called prostaglandins. Prostaglandins occur naturally in the body and are involved in many biological functions. Epoprostenol is used to treat the symptoms of primary pulmonary hypertension, or the high blood pressure that occurs in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. When the smaller blood vessels in the lungs become more resistant to blood flow, the right ventricle must work harder to pump enough blood through the lungs. Epoprostenol works by relaxing blood vessels and increasing the supply of blood to the lungs, reducing the workload of the heart.

This medicine is available only with your doctor's prescription, in the following dosage form(s):

Parenteral
• Injection (U.S. and Canada)

Parenteral
• Injection, vial or prefilled syringe (U.S.)

Enalapril ( e-NAL-a-pril) and felodipine (fe-LOE-di-peen ) combination belongs to the class of medicines called high blood pressure medicines (antihypertensives). This medicine is used to treat high blood pressure (hypertension).

High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

The exact way in which this medicine works is not known. Enalapril is a type of medicine known as an angiotensin-converting enzyme (ACE) inhibitor. It blocks an enzyme in the body that is necessary in producing a substance that causes blood vessels to tighten. Felodipine is a type of medicine known as a calcium channel blocker. Calcium channel blocking agents affect the movement of calcium into the cells of the heart and blood vessels. The actions of both medicines relax blood vessels, lower blood pressure, and increase the supply of blood and oxygen to the heart.

This medicine is available only with your doctor's prescription, in the following dosage form:

Oral
• Tablets (U.S.)

Efavirenz ( eh-FAH-vih-rehnz) is used with other medicines in the treatment of the infection caused by the human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS).

Efavirenz will not cure or prevent HIV infection or AIDS; however, it helps keep HIV from reproducing and appears to slow down the destruction of the immune system. This may help delay the development of problems that usually result from AIDS or HIV disease. Efavirenz will not keep you from spreading HIV to other people. People who receive this medicine may continue to have some of the problems usually related to AIDS or HIV disease.

This medicine is available only with your doctor's prescription, in the following dosage form(s):

Oral
• Capsules (U.S.)
• Tablets (U.S.)

Eprosartan (ep-roe-SAR-tan ) belongs to the class of medicines called angiotensin II inhibitors. It is used to treat high blood pressure (hypertension).

Exemestane (ex-uh-MESS-tane ) is a medicine that is used to treat breast cancer in women whose disease has progressed while they were taking tamoxifen ( ta-MOX-i-fen) .

Many breast cancer tumors grow in response to estrogen. Exemestane interferes with the production of estrogen in the body. As a result, the amount of estrogen that the tumor is exposed to is reduced, limiting the growth of the tumor. This medicine is meant to be used only by women who have already stopped menstruating.

Before you begin treatment with exemestane, you and your doctor should talk about the good this medicine will do as well as the risks of using it.

Exemestane is available only with your doctor's prescription, in the following dosage form:
