| Rx | Description |
|---|---|
| Repaglinide | Repaglinide is used to treat type II (noninsulin-dependent) diabetes (formerly 'adult-onset'). Repaglinide helps your body regulate the amount of glucose (sugar) in your blood. It decreases the amount of glucose by stimulating the pancreas to release insulin. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Ranitidine | Ranitidine is used to treat ulcers; gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and injury of the food pipe (esophagus); and conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome. Over-the-counter ranitidine is used to prevent and treat symptoms of heartburn associated with acid indigestion and sour stomach. Ranitidine is in a class of medications called H 2 |
| Reserpine | Reserpine is used to treat high blood pressure. It works by decreasing your heart rate and relaxing the blood vessels so that blood can flow more easily through the body. It also is used to treat severe agitation in patients with mental disorders. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Reserpine, Hydralazine, and Hydrochlorothiazide | The combination of reserpine, hydralazine, and hydrochlorothiazide is used to treat high blood pressure. Reserpine and hydralazine work by relaxing the blood vessels so that blood can flow more easily through the body. Hydrochlorothiazide helps to lower blood pressure by eliminating unneeded water and salt from the body. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Rizatriptan | Rizatriptan is used to relieve migraine headache symptoms. However, it will not prevent migraine headaches or reduce the number of headaches that you have. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Ranitidine Hydrochloride Injection | |
| Risedronate | Risedronate is used to prevent and treat osteoporosis (a condition in which the bones become thin and weak and break easily) in women who have undergone menopause (change of life). Risedronate is also used to prevent and treat osteoporosis in men and women who are taking glucocorticoids (corticosteroids; a type of medication that may cause osteoporosis). Risedronate is also used to treat Paget's disease of the bone (a condition in which the body replaces healthy bones with weak bones). Risedronate is in a class of medications called bisphosphonates. It works by preventing bone breakdown and increasing bone density (thickness) to make bones stronger and less likely to break. |
| Rivastigmine | Rivastigmine is used for the treatment of Alzheimer's disease. Rivastigmine is in a class of medications called cholinesterase inhibitors. It improves mental function by increasing the amount of a certain natural substance in the brain. |
| Rosuvastatin | Rosuvastatin is used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in your blood. Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and therefore the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats may help to prevent heart disease, angina (chest pain), strokes, and heart attacks. Rosuvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by preventing the body from forming harmful cholesterol and increasing the amount of HDL ('good cholesterol') in your blood. |
| Rifaximin | Rifaximin is used to treat traveler's diarrhea caused by certain bacteria. Rifaximin is in a class of medications called antibiotics. It works by preventing the bacteria from growing inside the intestine (gut). Rifaximin will not work to treat bloody diarrhea or diarrhea with fever. |
| Rifampin | Rifampin eliminates bacteria that cause tuberculosis (TB). It is generally used with other drugs to treat tuberculosis or to eliminate Neisseria meningitidis (a bacteria) and to prevent you from giving these infections to others. However, rifampin is not used to treat Neisseria meningitidis infection. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Ranitidine Bismuth Citrate | Ranitidine bismuth is used to treat intestinal ulcers. It helps fight infection by Helicobacter pylori bacteria, which often occurs with ulcers. Treating this infection helps keep ulcers from coming back. It is used in combination with other medicines. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Ramipril | Ramipril is used alone or in combination with other medications to treat high blood pressure. It is also used to reduce the risk of heart attack and stroke in patients at risk for these problems and to improve survival in patients with heart failure after a heart attack. Ramipril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors. It works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly and the heart can pump blood more efficiently. |
| Rifabutin | Rifabutin helps to prevent or slow the spread of Mycobacterium avium complex (MAC) disease in patients with human immunodeficiency virus (HIV) infection. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Risperidone | Risperidone is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Risperidone is in a class of medications called atypical antipsychotics. It works by decreasing abnormal excitement in the brain. |
| Riluzole | Riluzole is used to slow the progress of amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease). The drug also may delay the need for a tracheostomy (breathing tube), but it is not a cure for ALS. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Ritonavir | Ritonavir is used to treat human immunodeficiency virus (HIV) infection. It belongs to a class of drugs called protease (pro' tee ace) inhibitors, which slow the spread of HIV infection in the body. It is usually taken with other antiviral medications. Ritonavir is not a cure and may not decrease the number of HIV-related illnesses. Ritonavir does not prevent the spread of HIV to other people. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Raloxifene | Raloxifene is used to prevent and treat osteoporosis, a disease common in women past menopause, which results in bones that break easily. Raloxifene is in a class of medications called selective estrogen receptor modulators (SERMs). It works by acting similar to estrogen, a female hormone produced by the body. Like estrogen, raloxifene increases the density of bone. |
| Ropinirole | Ropinirole is used to treat the symptoms of Parkinson's disease, including tremors (shaking), stiffness, and slowness of movement. |
| Rimantadine | Rimantadine is used to prevent and treat infections caused by influenza A virus. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Rosiglitazone | Rosiglitazone is used, alone or in combination with other medications, to treat type 2 (noninsulin-dependent) diabetes (formerly 'adult-onset') in people whose diabetes cannot be controlled by diet and exercise alone. Rosiglitazone is in a class of drugs called thiazolidinediones. These drugs work by increasing your body's sensitivity to insulin, a substance your body produces to help control blood sugar levels. Rosiglitazone is not used to treat type 1 (insulin-dependent) diabetes (formerly 'juvenile-onset'). This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. |
| Rofecoxib | Rofecoxib is used to relieve the pain, tenderness, inflammation (swelling), and stiffness caused by arthritis and to treat painful menstrual periods and pain from other causes. Rofecoxib is in a class of nonsteroidal anti-inflammatory medications (NSAIDs) called COX-2 inhibitors. It works by stopping the body's production of a substance that causes pain and inflammation. COX-2 inhibitors may cause less stomach bleeding and ulcers than similar medications. |
| Rabeprazole | Rabeprazole is used to treat conditions where the stomach produces too much acid, including ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. Rabeprazole is used in combination with other medications to eliminate H. pylori |
| Radiopaque Agents Diagnostic (Local) | Radiopaque agents are drugs used to help diagnose certain medical problems. They contain iodine, which blocks x-rays. Depending on how the radiopaque agent is given, it localizes or builds up in certain areas of the body. The resulting high level of iodine allows the x-rays to make a ``picture'' of the area. The areas of the body in which the radiopaque agent localizes will appear white on the x-ray film. This creates the needed distinction, or contrast, between one organ and other tissues. The contrast will help the doctor see any special conditions that may exist in that organ or part of the body. The local radiopaque agents are used in the diagnosis of:
A catheter or syringe is used to put the solution of the radiopaque agent into the bladder or ureters to help diagnose problems or diseases of the kidneys or other areas of the urinary tract. It may also be placed into the uterus and fallopian tubes to help diagnose problems or disease of those organs. After the test is done, the patient expels most of the solution by urinating (after bladder or ureter studies) or from the vagina (after uterine or fallopian tube studies). Radiopaque agents are classified by their osmolality (a measure of concentration). There are high- and low-osmolality contrast agents. Low-osmolality agents are newer and more expensive than the high-osmolality ones. For most patients, a high-osmolality contrast agent is a good and safe choice. However, some patients are considered to be at a greater risk of having severe reactions to a radiopaque agent. Patients at risk are those who have had a severe reaction to radiopaque agents in the past. Also, patients with asthma or a history of allergies may be at a greater risk of severe reactions. For these patients, a low-osmolality contrast agent may be chosen. If you have any questions about this, check with the radiologist. The doses of radiopaque agents will be different for different patients and depend on the type of test. The strength of the solution is determined by how much iodine it contains. Different tests will require a different strength and amount of solution depending on the age of the patient, the contrast needed, and the x-ray equipment used. Also, for tests of the kidneys and other areas of the urinary tract, the amount of solution to be used depends on the size of the bladder. Radiopaque agents are to be used only by or under the supervision of a doctor in radiology or a radiologist. |
| Rauwolfia Alkaloids (Systemic) | Rauwolfia alkaloids belong to the general class of medicines called antihypertensives. They are 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. Rauwolfia alkaloids work by controlling nerve impulses along certain nerve pathways. As a result, they act on the heart and blood vessels to lower blood pressure. Rauwolfia alkaloids may also be used to treat other conditions as determined by your doctor. These medicines are available only with your doctor's prescription, in the following dosage forms:
|
| Rauwolfia Alkaloids and Thiazide Diuretics (Systemic) | Rauwolfia alkaloid and thiazide diuretic combinations are used in the treatment of 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. Rauwolfia alkaloids work by controlling nerve impulses along certain nerve pathways. As a result, they act on the heart and blood vessels to lower blood pressure. Thiazide diuretics help to reduce the amount of water in the body by increasing the flow of urine. This also helps to lower blood pressure. These medicines are available only with your doctor's prescription, in the following dosage forms:
|
| Reserpine, Hydralazine, and Hydrochlorothiazide (Systemic) | Reserpine, hydralazine, and hydrochlorothiazide (re-SER-peen, hye-DRAL-a-zeen, and hye-droe-KLOR-oh-THYE-a-zide) combinations are 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. Reserpine works by controlling nerve impulses along certain nerve pathways. As a result, it acts on the heart and blood vessels to lower blood pressure. Hydralazine works by relaxing blood vessels and increasing the supply of blood to the heart while reducing its work load. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps to reduce the amount of water in the body by increasing the flow of urine. This also helps to lower blood pressure. This medicine is available only with your doctor's prescription, in the following dosage form:
|
| Resorcinol (Topical) | Resorcinol (re-SOR-si-nole) is used to treat acne, seborrheic dermatitis, eczema, psoriasis, and other skin disorders. It is also used to treat corns, calluses, and warts. Resorcinol works by helping to remove hard, scaly, or roughened skin. Some of these preparations are available only with your doctor's prescription. Others are available without a prescription; however, your doctor may have special instructions on the proper use of resorcinol for your medical condition. Resorcinol is available in the following dosage forms:
|
| Resorcinol and Sulfur (Topical) | Resorcinol and sulfur ( re-SOR-si-nole and SUL-fur) combination is used to treat acne and similar skin conditions. This medicine is available without a prescription; however, your doctor may have special instructions on the proper use of this medicine for your medical condition. Resorcinol and sulfur combination is available in the following dosage forms:
|
| Ribavirin (Systemic) | Ribavirin (rye-ba-VYE-rin) is used to treat severe virus pneumonia in infants and young children. It is given by oral inhalation (breathing in the medicine as a fine mist through the mouth), using a special nebulizer (sprayer) attached to an oxygen hood or tent or face mask. Ribavirin taken by mouth (oral) treats a viral liver infection known as hepatitis C. It is used in combination with injectable interferon alfa-2b ( in-ter-FEER-on AL-fa-2b) or with injectable peginterferon alfa-2b (peg-in-ter-FEER-on AL-fa-2b) . Ribavirin is used to treat virus infections. Interferons are substances naturally produced by cells in the body to help fight infections and tumors. Interferon alfa-2b and peginterferon alfa-2b are synthetic (man-made) versions of these substances. Interferon alfa-2b and peginterferon alfa-2b are used to treat a variety of tumors and viruses including the hepatitis C virus. Ribavirin is available in the following dosage forms:
|
| Riboflavin (Vitamin B 2) (Systemic) | 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. Riboflavin (RYE-boe-flay-vin) (vitamin B 2) is needed to help break down carbohydrates, proteins, and fats. It also makes it possible for oxygen to be used by your body. Lack of riboflavin may lead to itching and burning eyes, sensitivity of eyes to light, sore tongue, itching and peeling skin on the nose and scrotum, and sores in the mouth. Your doctor may treat this condition by prescribing riboflavin for you. Some conditions may increase your need for riboflavin. These include:
In addition, riboflavin may be given to infants with high blood levels of bilirubin (hyperbilirubinemia). Increased need for riboflavin should be determined by your health care professional. Claims that riboflavin is effective for treatment of acne, some kinds of anemia (weak blood), migraine headaches, and muscle cramps have not been proven. Oral forms of riboflavin are available without a prescription. If you take more than you need, it will simply be lost from your body. Riboflavin is available in the following dosage form:
