Diovan General Information

Diovan is the trade name of the drug valsartan, which is used to treat heart disorders such as high blood pressure, post-myocardial infarction, and congestive heart failure.

How does Diovan work?

Diovan is an angiotensin receptor blocker, meaning that it blocks receptors which are responsible for constricting blood vessels and the production of hormones vasopressin and aldosterone. By blocking these receptors, Diovan is able to dilate blood vessels, and cause a net decrease in blood pressure. This combination of several effects on the body is ideal for helping to treat hypertension, usually above 140/90 mm/Hg. In addition to allowing blood to flow to the heart, Diovan prevents the release of the hormone renin, normally responsible for causing salt retention in the kidneys. This action is important in conjunction with Diovan's vasodilatory properties for helping to treat heart failure and heart attacks. There has been some preliminary research into using Diovan to prevent or treat Alzheimer's disease, and while the initial findings are promising, there is no conclusive evidence that Diovan is an effective treatment.

When/How is Diovan taken/used/applied?

When Diovan is being taken to reduce hypertension, it is taken orally and sometimes in conjunction with other antihypertensive agents. If Diovan is used to treat heart failure or post-mycardial infarction, it is usually not taken with other medications. Unlike many medications, Diovan does not have to be taken with food, but it should be taken orally once a day, at the same time daily. Starting dosages usually range from 80 to 160 mg per day, but up to 320 mg a day may be used depending on the severity of the patient's medical situation.

Side Effects of Diovan

Diovan is usually well-tolerated by most patients, and side effects tend to be rare and short-lasting. No reported side effects have been shown to persist beyond ceasing usage of the medication, and since the side effects tend to be mild, few patients have to discontinue use of Diovan due to side effects. For patients taking Diovan for hypertension, the most common side effects reported were headaches and dizziness, but coughs, diarrhea, and indigestion occurred in about 1% of patients taking the medication. In patients taking Diovan for post-myocardial infarction or congenital heart failure, side effects were a bit more common (around 5-17%) than in the hypertension group, but again, were relatively rare and tolerable. Hypotension was seen in some patients taking Diovan in these groups, but again, the main side effects seen were headaches and dizziness. Occasionally a sensitivity to light developed in some patients taking Diovan, as well.

Other Brand Names for Diovan:

Diovan HCT contains a combination of valsartan and hydrochlorothiazide, and is only used to treat hypertension.Diovan (valsartan) is still under patent protection, so no other brand names or generics are available.

Safety Information:

Pregnant women should avoid using Diovan, since the renin-angiotensin system is utilized by fetuses in order to develop properly. Drugs such as Diovan which cause changes to this system can lead to birth defects or stillbirth. In adults, however, Diovan is well-tolerated by most individuals, although overuse can lead to changes in consciousness, hypotension, and dizziness. For this reason, regular visits with a doctor are necessary while taking this medication. Individuals at risk for myocardial infarction, but who are not being treated for post-myocardial infarction may want to avoid Diovan as a preventative measure, since in isolated cases Diovan may increase the chance of a heart attack.

    • About Diovan

      What Diovan is used for

      DIOVAN is used to lower blood pressure or to treat people after a heart attack (myocardial infarction) when the use of an angiotensin-converting enzyme (ACE) inhibitor, considered part of standard therapy for this condition, is not appropriate.

      DIOVAN is also used in patients with chronic heart failure, when they are unable to tolerate the standard treatment with medications called ACE inhibitors. There is no evidence that DIOVAN provides added benefit when it is used with ACE inhibitors.

      High blood pressure increases the workload of the heart and arteries. If this condition continues for a long time, damage to the blood vessels of the brain, heart, and kidneys can occur, and may eventually result in a stroke, heart failure or kidney failure. High blood pressure also increases the risk of heart attacks. Reducing your blood pressure decreases your risk of developing these illnesses.

      What Diovan does

      DIOVAN belongs to a class of medicines known as angiotensin II receptor blocker, which help to control high blood pressure or other heart-related problems. Angiotensin II is a natural hormone produced in the body to keep blood pressure at normal levels. One function of angiotensin II is to increase blood pressure, usually when it becomes too low. DIOVAN works by blocking the effect of angiotensin II. As a result, blood pressure is lowered.

      When Diovan should not be used

      You should not take DIOVAN if:

      • you have ever had an unusual or allergic reaction to valsartan or to any other component of this product,

      • you are pregnant or plan to become pregnant.

      DIOVAN is not recommended for children and adolescents (below the age of 18 years).

      Warnings and Precautions

      Serious Warnings and Precautions

      DIOVAN should not be used during pregnancy. If you discover that you are pregnant while taking DIOVAN, stop the medication and please contact your physician.

      BEFORE you use DIOVAN talk to your doctor or pharmacist if:

      • you have a kidney or liver disease

      • you are being treated with diuretics

      • you are suffering from excess vomiting or diarrhea

      • you have any allergies to this drug or its ingredients or components of the container

      You are pregnant, breast-feeding or thinking of becoming pregnant?

      Taking DIOVAN during pregnancy can cause injury and even death to your baby. This medicine should not be used during pregnancy. If you are planning to become pregnant while taking DIOVAN, contact immediately your doctor.

      It is possible that DIOVAN passes into breast milk. You should discuss with you doctor about taking DIOVAN while breastfeeding.

      Similar medicines were associated with serious harm to fetuses when they were taken after the first three months of pregnancy. (It is not known if they are harmful during the first three months.) It is therefore important to tell your doctor immediately if you think you may have become pregnant, or planning to become pregnant. Your doctor will discuss with you the potential risk of taking DIOVAN during pregnancy.

      Although it is not known whether DIOVAN can pass into human breast milk, this does happen in animals. Therefore do not breast-feed during treatment. Tell your doctor if you are breast-feeding, so that other treatment options can be tried.

      Like many other medicines used to treat high blood pressure, DIOVAN may rarely cause dizziness and affect your concentration. So before you drive a vehicle, use machinery, or do other things that need concentration, make sure you know how you react to the effects of DIOVAN.

      Interactions with Diovan

      As with other medicines, interactions with other drugs are possible. Therefore, do not take any other medicines unless you have discussed the matter with your physician or your pharmacist.

      Drugs that may interact with DIOVAN include:

      • medicines used to lower blood pressure, including diuretics (water pills),

      • potassium-sparing medicines, potassium supplements, or salt substitutes containing potassium,

      • lithium therapy.

      Before taking DIOVAN make sure your doctor knows about all the medications you are taking, including those not prescribed by your doctor. It may be necessary to change the dose, take other precautions, or perhaps stop one of the medicines. This applies to both prescription and non-prescription medicines.

      Proper Use of Diovan

      If your doctor has prescribed DIOVAN for you following a heart attack, it is important to continue to take it even if you feel well, so that DIOVAN can help to reduce the chance of another heart attack occurring.

      Patients who have high blood pressure often do not notice any signs or symptoms of this condition. So even though you are feeling well, your health may be getting worse. This makes it all the more important for you to continue your treatment program and to keep your appointments with your doctor.

      Remember that this medicine does not cure your high blood pressure; it only may help to control it. Therefore, if you want to lower your blood pressure and keep it down, you must continue to take DIOVAN as directed.

      Usual dose

      It is very important that you take this medicine exactly as your doctor tells you in order to get the best results and reduce the chance of side effects.

      High blood pressure (hypertension)

      The usual dosage for the treatment of high blood pressure is one 80 mg tablet once a day. In some cases, your doctor may increase the dose to 160 mg and then eventually to 320 mg or prescribe it together with another medicine (e.g., a diuretic).

      Following a heart attack (myocardial infarction)

      Treatment is generally started as soon as 12 hours following the heart attack, usually at a low dose of 20 mg twice daily in order to minimise side effects including hypotension (low blood pressure). Your doctor may increase this dose gradually over several weeks to a maximum of 160 mg twice daily.

      Failing heart (heart failure)

      Treatment is generally started at a dose of 40 mg twice daily in order to minimize side effects including low blood pressure. Your doctor may increase this dose gradually over several weeks to a maximum of 160 mg twice daily.

      Swallow DIOVAN tablets with a glass of water. You can take DIOVAN with or without food, but it should be taken the same way each day and at the same time.


      If you have accidentally taken too many tablets of DIOVAN, seek medical assistance immediately.

      For management of a suspected drug overdose, contact your regional Poison Control Centre.

      Missed dose

      Try to take your dose at the same time each day, preferably in the morning. However, if you have forgotten to take your dose during the day, carry on with the next one at the usual time. Do not take a double dose to make up for the forgotten tablet.

      Side Effects for Diovan and What to Do About Them

As a person who has to manage their blood pressure, I was relieved to find your website because my doctor has prescribed me Diovan. I can buy Diovan from one of your pharmacies, and save enough money over time to buy my wife something special. Oh yeah, she thanks you too.
