What is valsartan, and how does it work (mechanism of action)?
WARNING: The U.S. Food and Drug Administration is alerting health care professionals and patients of a voluntary recall of several drug products containing the active ingredient valsartan, used to treat high blood pressure and heart failure. This recall is due to an impurity, N-nitrosodimethylamine (NDMA), which was found in the recalled products. However, not all products containing valsartan are being recalled. NDMA is classified as a probable human carcinogen (a substance that could cause cancer) based on results from laboratory tests. Don't stop taking valsartan suddenly. Talk to your doctor if you are currently taking valsartan.
What is valsartan, and how does it work (mechanism of action)?
Valsartan is an oral medication that is used to treat high blood pressure and congestive heart failure. It belongs to a class of drugs called angiotensin receptor blockers (ARBs) which also includes irbesartan (Avapro), losartan (Cozaar), and candesartan (Atacand). Angiotensin, formed in the blood by the action of angiotensin converting enzyme (ACE), is a powerful chemical that attaches to angiotensin receptors found in many tissues but primarily on smooth muscle cells of blood vessels. Angiotensin's attachment to the receptors causes the blood vessels to narrow (vasoconstrict) which leads to an increase in blood pressure (hypertension ). Valsartan blocks the angiotensin receptor. By blocking the action of angiotensin, valsartan dilates blood vessels and reduces blood pressure. Valsartan was approved by the FDA in December 1996.

What are the uses for valsartan?
What are the side effects of valsartan?
Valsartan is generally well-tolerated. The most common side effects are:
Other important side effects are:
What is the dosage for valsartan?
The usual dose of valsartan for adults with high blood pressure is 80 to 160 mg once daily. The maximum dose is 320 mg daily. Maximum blood pressure reduction occurs within 4 weeks. For congestive heart failure, the usual dose is 40 mg twice daily. The doses may be increased to 80-160 mg twice daily. The initial dose after a heart attack is 20 mg twice daily. The dose may be increased to 160 mg twice daily if tolerated without side effects.
Which drugs or supplements interact with valsartan?
Combining valsartan with potassium-sparing diuretics (for example., spironolactone (Aldactone), triamterene, amiloride), potassium supplements, or salt substitutes containing potassium may lead to hyperkalemia (elevated potassium in the blood) and in heart failure patients, it increases serum creatinine, a blood test used for monitoring function of the kidneys.
Combining valsartan or other ARBs with nonsteroidal anti-inflammatory drugs (NSAIDs) in patients who are elderly, fluid-depleted (including those on diuretic therapy), or with poor kidney function may result in reduced kidney function, including kidney failure. These effects are usually reversible. There have been reports that aspirin and other NSAIDs such as ibuprofen (Advil, Children's Advil/Motrin, Medipren, Motrin, Nuprin, PediaCare Fever, etc.), indomethacin (Indocin, Indocin-SR), and naproxen (Anaprox, Naprelan, Naprosyn, Aleve) may reduce the effects of ARBs.
Is valsartan safe to take if I'm pregnant or breastfeeding?
When used in the second or third trimester of pregnancy , valsartan and similar drugs can cause injury and even death to the fetus. Valsartan should not be used during pregnancy. When pregnancy is detected, valsartan should be stopped as soon as possible.
It is not known whether valsartan is secreted into human milk. Valsartan is secreted into the milk of rats.

Examples of ARBs include candesartan (Atacand), eprosartan (Teveten), irbesartan (Avapro), telmisartan (Micardis), valsartan (Diovan), losartan (Cozaar), and olmesartan (Benicar). Side effects, drug interactions, and patient safety information should be reviewed prior to taking any medication.

Side effects, drug interactions, warnings and precauctions, dosage, what the drug is used for, what to do if you miss a dose, how the drug is to be stored, and generic vs. brand names.
Febrile SeizuresFebrile seizures, or convulsions caused by fever, can be frightening in small children or infants. However, in general, febrile seizures are harmless. Febrile seizure is not epilepsy. It is estimated that one in every 25 children will have at least one febrile seizure. It is important to know what to do to help your child if he/she has a febrile seizure. Some of the features of a febrile seizure include:
- losing consciousness,
- moving limbs on both sides of the body,
- lasts 1-2 minutes.
High Blood Pressure Hypertension
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.
