Tamoxifen ( ta-MOX-i-fen) is a medicine that blocks the effects of the estrogen hormone in the body. It is used to treat breast cancer in women or men. It may also be used to treat other kinds of cancer, as determined by your doctor.

Tamoxifen also may be used to reduce the risk of developing breast cancer in women who have a high risk of developing breast cancer. Women at high risk for developing breast cancer are at least 35 years of age and have a combination of risk factors that make their chance of developing breast cancer 1.67% or more over the next 5 years. Your doctor will help to determine your risk of developing breast cancer.

The following are risk factors that may increase your chance of developing breast cancer:
• If you have close family members (mother, sister, or daughter) with breast cancer
• If you have ever had a breast biopsy or if high-risk changes in your breast(s) have been found from a breast biopsy
• If you have never been pregnant or if your first pregnancy occurred at a late age
• If your first menstrual period occurred at an early age

The exact way that tamoxifen works against cancer is not known, but it may be related to the way it blocks the effects of estrogen on the body.

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

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

Oral
• Tablets (U.S. and Canada)

Teriparatide (ter-i-PAR-a-tide) is a synthetic form of the natural human parathyroid hormone and is used by injection to treat osteoporosis. Teriparatide forms new bone, increases bone mineral density and bone strength, and as a result reduces the chance of getting a fracture (broken bone). Teriparatide can be used by men or postmenopausal women with osteoporosis who are at high risk for having fractures. Teriparatide can be used by people who have had a fracture related to osteoporosis, or who have multiple risk factors for fracture, or who cannot use other osteoporosis treatments.

Teriparatide has been used by injection into a vein as a test to help diagnose problems of the parathyroid gland. This test determines whether you have hypoparathyroidism or a type of pseudohypoparathyroidism.

This product, for use as a test to help diagnose problems of the parathyroid gland, was withdrawn from the U.S. market in January 1997.

Tetanus (TET-n-us) Toxoid is used to prevent tetanus (also known as lockjaw). Tetanus is a serious illness that causes convulsions (seizures) and severe muscle spasms that can be strong enough to cause bone fractures of the spine. Tetanus causes death in 30 to 40 percent of cases.

Immunization against tetanus is recommended for all infants 6 to 8 weeks of age and older, all children, and all adults. Immunization against tetanus consists first of a series of either 3 or 4 injections, depending on which type of tetanus toxoid you receive. In addition, it is very important that you get a booster injection every 10 years for the rest of your life. Also, if you get a wound that is unclean or hard to clean, you may need an emergency booster injection if it has been more than 5 years since your last booster. In recent years, two-thirds of all tetanus cases have been in persons 50 years of age and older. A tetanus infection in the past does not make you immune to tetanus in the future.

This vaccine is to be administered only by or under the supervision of your doctor or other health care professional. It is available in the following dosage form:

Parenteral
• Injection (U.S. and Canada)

Tetracyclines are used to treat infections and to help control acne. Demeclocycline, doxycycline, and minocycline also may be used for other problems as determined by your doctor. Tetracyclines will not work for colds, flu, or other virus infections.

Vitamins (VYE-ta-mins) are compounds that you must have for growth and health. They are needed in small amounts only and are usually available in the foods that you eat. Thiamine (THYE-a-min) (vitamin B 1) is needed for the breakdown of carbohydrates.

Some conditions may increase your need for thiamine. These include:

• Alcoholism
• Burns
• Diarrhea (continuing)
• Fever (continuing)
• Illness (continuing)
• Intestinal disease
• Liver disease
• Overactive thyroid
• Stress (continuing)
• Surgical removal of stomach

Also, the following groups of people may have a deficiency of thiamine:

• Patients using an artificial kidney (on hemodialysis)
• Individuals who do heavy manual labor on a daily basis

Increased need for thiamine should be determined by your health care professional.

Lack of thiamine may lead to a condition called beriberi. Signs of beriberi include loss of appetite, constipation, muscle weakness, pain or tingling in arms or legs, and possible swelling of feet or lower legs. In addition, if severe, lack of thiamine may cause mental depression, memory problems, weakness, shortness of breath, and fast heartbeat. Your health care professional may treat this by prescribing thiamine for you.

Thiamine may also be used for other conditions as determined by your health care professional.

Claims that thiamine is effective for treatment of skin problems, chronic diarrhea, tiredness, mental problems, multiple sclerosis, nerve problems, and ulcerative colitis (a disease of the intestines), or as an insect repellant or to stimulate appetite have not been proven.

Tacrine (TAK-reen) is used to treat the symptoms of mild to moderate Alzheimer's disease. Tacrine will not cure Alzheimer's disease, and it will not stop the disease from getting worse. However, tacrine can improve thinking ability in some patients with Alzheimer's disease.

In Alzheimer's disease, many chemical changes take place in the brain. One of the earliest and biggest changes is that there is less of a chemical messenger called acetylcholine (ACh). ACh helps the brain to work properly. Tacrine slows the breakdown of ACh, so it can build up and have a greater effect. However, as Alzheimer's disease gets worse, there will be less and less ACh, so tacrine may not work as well.

Tacrine may cause liver problems. While taking this medicine, you must have blood tests regularly to see if the medicine is affecting your liver.

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

Oral
• Capsules (U.S.)

Torsemide (TORE-se-mide ) belongs to the group of medicines called loop diuretics. Torsemide is given to help reduce the amount of water in the body in certain conditions, such as congestive heart failure, severe liver disease (cirrhosis), or kidney disease. It works by acting on the kidneys to increase the flow of urine.

Torsemide is also used to treat high blood pressure (hypertension). High blood pressure adds to the work load 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.

Torsemide is available only with your doctor's prescription, in the following dosage forms:

Oral
• Tablets (U.S.)

Parenteral
• Injection (U.S.)

Tuberculin (too-BER-kyu-lin) , purified protein derivative (PPD) is used as a test to help diagnose tuberculous infection.

How the test is done: Tuberculin PPD is injected into the surface layers of the skin. If the test is positive, a reaction will be seen at and around the place of injection or puncture. If the test is given using an injection, this reaction is usually a hard, raised area with clear margins. If the test is given using the puncture devices, the reaction is usually a swollen area at the puncture site. Forty-eight to 72 hours after administration of the injection the size of the reaction is measured and recorded and the results of the test are studied.

Tuberculin PPD is to be used only by or under the supervision of a doctor. It is available in the following dosage forms:

Parenteral
• Injection (U.S. and Canada)
• Multiple-puncture device (U.S.)

Typhoid (TYE-foid) fever is a serious disease that can cause death. It is caused by a germ called Salmonella typhi, and is spread most often through infected food or water. Typhoid may also be spread by close person-to-person contact with infected persons (such as occurs with persons living in the same household). Some infected persons do not appear to be sick, but they can still spread the germ to others.

Typhoid fever is very rare in the U.S. and other areas of the world that have good water and sewage (waste) systems. However, it is a problem in parts of the world that do not have such systems. If you are traveling to certain countries or remote, out-of-the-way areas, typhoid vaccine will help protect you from typhoid fever. The U.S. Centers for Disease Control (CDC) currently recommend caution in the following areas of the world:

• Africa
• Asia
• Latin America

Typhoid vaccine given by injection helps prevent typhoid fever, but does not provide 100% protection. Therefore, it is very important to avoid infected persons and food and water that may be infected, even if you have received the vaccine.

To get the best possible protection against typhoid, you should receive the vaccine at least 1 week before you travel to areas where you may be exposed to typhoid.

If you will be traveling regularly to parts of the world where typhoid is a problem, you should get a booster (repeat) dose of the vaccine every 2 years.

Typhoid vaccine is to be used only by or under the supervision of a doctor. It is available in the following dosage form:

Parenteral
• Injection (U.S.)

Tetanus immune globulin (TET-n-us im-MUNE GLOB-yoo-lin) is used to prevent tetanus infection (also known as lockjaw). Tetanus is a serious illness that causes convulsions (seizures) and severe muscle spasms that can be strong enough to cause bone fractures of the spine. Tetanus causes death in 30 to 40 percent of cases.

In recent years, two thirds of all tetanus cases have been in persons 50 years of age and older. A tetanus infection in the past does not make you immune to tetanus in the future.

Tetanus immune globulin works by giving your body the antibodies it needs to protect it against tetanus infection. This is called passive protection. This passive protection lasts long enough to protect your body until your body can produce its own antibodies against tetanus.

Tetanus immune globulin is to be administered only by or under the supervision of your doctor or other health care professional. It is available in the following dosage form:

Parenteral
• Injection (U.S. and Canada)

Topotecan (toe-poe-TEE-kan ) belongs to the group of medicines known as antineoplastics. It is used to treat cancer of the ovaries and certain types of lung cancer.

Topotecan interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal cells may also be affected by the medicine, other effects may 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 occur after treatment with topotecan has been stopped.

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

Parenteral
• Injection (U.S. and Canada)

Tetanus antitoxin ( TET-uh-nus AN-ti-TOK-sin) is used to prevent and/or treat tetanus infection (also known as lockjaw). Tetanus is a serious illness that causes convulsions (seizures) and severe muscle spasms that can be strong enough to cause bone fractures of the spine. Tetanus causes death in 30 to 40 percent of people who get it.

In recent years, two thirds of all tetanus cases have been in persons 50 years of age and older. Having a tetanus infection in the past does not make you immune to tetanus in the future.

Tetanus antitoxin works by giving your body the antibodies it needs to protect it against tetanus infection. This is called passive protection. This passive protection lasts long enough to protect you until your body can produce its own antibodies against tetanus.

Tetanus antitoxin is to be administered only by or under the supervision of your doctor or other health care professional. It is available in the following dosage form:

Parenteral
• Injection (Africa, Asia, and Latin America)

Alatrofloxacin and trovafloxacin are used to treat very serious bacterial infections in many different parts of the body. They work by killing bacteria or preventing their growth. However, these medicines will not work for colds, flu, or other virus infections.

Liver failure has been reported rarely with the use of alatrofloxacin and trovafloxacin. Because of the risk of liver problems, these medicines are used only to treat serious bacterial infections, such as those that are life-threatening or when there is a risk of losing a limb. Because of this, treatment usually is started in the hospital or in another in-patient health care facility.

These medicines are available only with your doctor's prescription, in the following dosage forms:

Oral
• Trovafloxacin
  • Tablets (U.S.)

Parenteral
• Alatrofloxacin
  • Injection (U.S.)

Tamsulosin (tam-SOO-loh-sin) is used to treat the signs and symptoms of benign enlargement of the prostate (benign prostatic hyperplasia or BPH). Benign enlargement of the prostate is a problem that can occur in men as they get older. The prostate gland is located below the bladder. As the prostate gland enlarges, certain muscles in the gland may become tight and get in the way of the tube that drains urine from the bladder. This can cause problems in urinating, such as a need to urinate often, a weak stream when urinating, or a feeling of not being able to empty the bladder completely.

Tamsulosin helps relax the muscles in the prostate and the opening of the bladder. This may help increase the flow of urine and/or decrease the symptoms. However, tamsulosin will not shrink the prostate. The prostate may continue to get larger. This may cause the symptoms to become worse over time. Therefore, even though tamsulosin may lessen the problems caused by enlarged prostate now, surgery still may be needed in the future.

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

Oral
• Capsules (U.S.)

Talc is sprayed through a tube into the area around the lungs. It is given to people who have breathing problems caused by a buildup of fluid in this area. Talc is used after the fluid has been drained out, to prevent the problem from returning.

You may be familiar with talc used as an ingredient in dusting powders (talcum powder). The talc used for preventing fluid buildup in the lungs is a special grade of talc that has been sterilized (made germ-free).

This medicine is to be given only by your doctor. It is available in the following dosage form:

Intrapleural (into the area around the lungs)-Local
• Aerosol spray (U.S.)

Trandolapril ( tran-DOHL-a-pril) and verapamil (ver-AP-a-mil ) combination belongs to the class of medicines called high blood pressure medicines (antihypertensives). It 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. Trandolapril 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. Verapamil 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
• Extended-release tablets (U.S.)

Tretinoin (TRET-i-noyn) belongs to the group of medicines known as retinoids (RET-i-noyds). It is used to treat a form of leukemia (acute promyelocytic leukemia [APL]).

Telmisartan ( tel-mi-SAR-tan) belongs to the class of medicines called angiotensin II inhibitors. It 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.

Telmisartan works by blocking the action of a substance in the body that causes blood vessels to tighten. As a result, telmisartan relaxes blood vessels. This lowers blood pressure.

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

Oral
• Tablets (U.S. and Canada)

Tizanidine ( tye-ZAN-i-dine) is used to help relax certain muscles in your body. It relieves the spasms, cramping, and tightness of muscles caused by medical problems such as multiple sclerosis or certain injuries to the spine. Tizanidine does not cure these problems, but it may allow other treatment, such as physical therapy, to be more helpful in improving your condition.

Tizanidine acts on the central nervous system (CNS) to produce its muscle relaxant effects. Its actions on the CNS may also cause some of the medicine's side effects.

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

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

Tioconazole (tye-o-KON-a-zole) belongs to the family of medicines called antifungals, which are used to treat infections caused by a fungus or yeast. They work by killing the fungus or yeast or preventing its growth.

Tioconazole cream is applied to the skin to treat :

• ringworm of the body (tinea corporis);
• ringworm of the foot (tinea pedis; athlete's foot);

Tinzaparin (tin-ZA-pa-rin) is used for the prevention and/or treatment of deep venous thrombosis, a condition in which harmful blood clots form in the blood vessels of the legs. These blood clots can travel to the lungs and can become lodged in the blood vessels of the lungs, causing a condition called pulmonary embolism. Tinzaparin is used for several days after surgery, while you are unable to walk. It is during this time that blood clots are most likely to form. Tinzaparin also may be used for other conditions as determined by your doctor.

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

Parenteral
• Injection (U.S. and Canada)

Tacrolimus ( ta-KROE-li-mus) ointment is used for moderate to severe atopic dermatitis. This is a skin condition where there is itching, redness and inflammation, much like an allergic reaction. Tacrolimus helps to suppress these symptoms which are a reaction caused by the body's immune system. It can be used for short-term or long-term intermittent treatment. It is often used when other types of treatment are not working or not tolerated by the patient.

Tacrolimus is available only with your doctor's prescription, in the following dosage forms:

Combination medicines containing narcotic analgesics (nar-KOT-ik an-al-JEE-zicks) such as tramadol (TRA-ma-dole ) and acetaminophen ( a-seat-a-MIN-oh-fen) are used to relieve pain. An opioid analgesic and acetaminophen used together may provide better pain relief than either medicine used alone. In some cases, you may get relief with lower doses of each medicine.

Opioid analgesics act in the central nervous system (CNS) to relieve pain. Many of their side effects are also caused by actions in the CNS. When opioids are used for a long time, your body may get used to them so that larger amounts are needed to relieve pain. This is called tolerance to the medicine. Also, when opioids are used for a long time or in large doses, they may become habit-forming (causing mental or physical dependence). Physical dependence may lead to withdrawal symptoms when you stop taking the medicine.

Acetaminophen does not become habit-forming when taken for a long time but it may cause other unwanted effects, when taken in large doses including liver damage, if too much is taken.
