Riva Irbesartan How to Take

Irbesartan belongs to a family of medicines known as angiotensin II receptor blockers. These medicines are used to lower high blood pressure and work by relaxing blood vessels. Irbesartan is also used to lower blood pressure and decrease the rate of the progression of kidney damage in patients with Type 2 Diabetes.

Angiotensin II is a chemical that the body releases to cause the constriction of blood vessels. Irbesartan blocks the action of angiotensin II, resulting in the relaxation of the blood vessels. This relaxation causes the blood pressure to decrease. The full effects of irbesartan are usually seen within about 4 weeks. It can be used alone or in combination with thiazide diuretics (water pills; e.g., Hydrochlorothiazide).

Riva Irbesartan does not cure high blood pressure, but it does help to control it, when it is taken regularly. Do not stop taking Riva Irbesartan without discussing the risks and benefits with your doctor.

Riva Irbesartan may be available under multiple brand names and/or in several different forms. Any specific brand name of Riva Irbesartan may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Riva Irbesartan may not be used for all of the conditions discussed here.

Your doctor may have suggested Riva Irbesartan for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Riva Irbesartan, speak to your doctor. Do not stop taking Riva Irbesartan without consulting your doctor.

Do not give Riva Irbesartan to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Riva Irbesartan if their doctor has not prescribed it.

Medications other than those listed above may interact with Riva Irbesartan. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.

Riva Irbesartan Warnings

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Riva Irbesartan.

Drowsiness/reduced alertness: Irbesartan, like other medications for blood pressure may cause dizziness and lightheadedness, especially if you have been taking a diuretic (water pill). This may affect your ability to drive or operate machinery. Avoid these and other activities until you have determined that Riva Irbesartan does not affect you in this way.

Heart disease: If you have a history of heart problems, such as a recent Heart Attack or Stroke, narrowing of the heart valves (valvular stenosis) or other heart disease, discuss with your doctor how Riva Irbesartan may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Riva Irbesartan, and whether any special monitoring is needed.

Kidney function: Irbesartan may affect the function of the kidneys, especially for people who already have kidney problems. Certain people may be more likely to experience changes in kidney function (e.g., people with narrowed blood vessels in their kidneys, or those with severe Congestive Heart Failure). The use of diuretics (water pills) or aliskiren may further increase risk of kidney problems for those at risk for this problem. If you have reduced kidney function or Kidney Disease, discuss with your doctor how Riva Irbesartan may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Riva Irbesartan, and whether any special monitoring is needed.

Liver function: Liver disease or reduced liver function may cause Riva Irbesartan to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Riva Irbesartan may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Riva Irbesartan, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking Riva Irbesartan.

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Low Blood Pressure: Occasionally, a larger-than-expected decrease in blood pressure occurs after taking irbesartan. In some cases, this happens after the first dose. It is more likely to occur if you take diuretics (water pills) or the medication aliskiren, have a reduced salt intake, are on dialysis, or are experiencing diarrhea or vomiting. Blood pressure should be monitored more often in these situations. If you have low blood pressure or are just starting to take Riva Irbesartan, move slowly from a reclining to an upright position to reduce the risk of dizziness.

Potassium levels: Riva Irbesartan may affect potassium levels in the blood, especially when used for heart failure, or when taken with other medications called ACE inhibitors or diuretics such as Spironolactone. Your doctor will monitor your potassium levels while you are on Riva Irbesartan. Avoid using salt substitutes that contain potassium while you are taking irbesartan.

Pregnancy: Irbesartan can cause severe harm or death to a developing baby if it is taken by the mother during pregnancy. Therefore, Riva Irbesartan should not be taken by pregnant women. If you become pregnant while taking Riva Irbesartan, contact your doctor immediately.

Breast-feeding: It is not known if irbesartan passes into breast milk. If you are a breast-feeding mother and are taking Riva Irbesartan, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using Riva Irbesartan have not been established for children.

Seniors: Older adults may be more likely to experience side effects of Riva Irbesartan.
