Diovan (generic name: valsartan) is a modern angiotensin II receptor blocker (ARB) used to treat high blood pressure (hypertension), manage certain cases of chronic heart failure, and improve survival after a heart attack (myocardial infarction). By selectively blocking the AT1 receptor for angiotensin II, Diovan prevents blood vessel constriction and reduces aldosterone effects, which lowers systemic vascular resistance, helps blood vessels relax and widen, and decreases the workload on the heart. The net effect is a sustained reduction in blood pressure and improved hemodynamics that support heart function.
Clinical uses include:
In addition to its core indications, clinicians may consider valsartan in patients with proteinuric kidney disease, particularly when ARBs are preferred over ACE inhibitors due to cough or angioedema. For patients with diabetes and hypertension, valsartan helps control blood pressure and may slow kidney damage when used as part of comprehensive care that includes diet, exercise, lipid management, and glucose control.
Diovan is FDA-approved, available as a branded product and as generic valsartan. It is also available in combination products such as valsartan/hydrochlorothiazide for patients requiring multi-mechanism control. Its once-daily dosing, favorable side effect profile compared to some alternatives, and cardioprotective benefits make it a cornerstone therapy in evidence-based cardiovascular care.
Take Diovan exactly as prescribed by your healthcare provider. The dose, frequency, and titration schedule depend on the condition being treated, coexisting medical issues, and your response to therapy. Diovan can be taken with or without food; try to take it at the same time each day to support adherence.
Swallow tablets whole with water. Do not crush or chew unless your prescriber advises an alternative form. If you are using an oral suspension for pediatric dosing, ensure it is prepared and measured accurately according to the pharmacist’s instructions.
Important administration tips:
Before starting Diovan, tell your healthcare provider about your medical history and all medications you take. The following considerations help ensure safe, effective use:
Do not take Diovan if you:
Use is generally not recommended with aliskiren in patients with renal impairment, and it should be avoided in severe hepatic dysfunction. For patients with bilateral renal artery stenosis or stenosis to a solitary kidney, use requires specialist guidance and close monitoring.
Most people tolerate Diovan well. When side effects occur, they are often mild and transient. Common effects include:
Serious adverse effects are uncommon but require prompt medical attention:
If you experience worrisome symptoms, contact your healthcare provider. Seek emergency help for severe reactions such as angioedema, difficulty breathing, syncope, or signs of dangerously high potassium.
Diovan can interact with other medications and supplements. Tell your healthcare team about all prescription drugs, over-the-counter medicines, vitamins, and herbal products you use. Notable interactions include:
Always consult your clinician before adding or stopping any medication while taking Diovan.
If you miss a dose of Diovan, take it as soon as you remember on the same day. If it is almost time for your next scheduled dose, skip the missed dose and take the next dose at the regular time. Do not take two doses at once to make up for a missed dose. To reduce missed doses, consider using reminders or a pill organizer.
Symptoms of overdose may include pronounced dizziness, fainting from low blood pressure, rapid or slow heartbeat, and in severe cases, circulatory collapse. If you suspect an overdose, call your local poison control center or seek emergency medical attention immediately. Supportive care typically includes laying the person supine with legs elevated, intravenous fluids if needed, and monitoring vital signs and kidney function. Bring the medication container to the emergency department if possible.
Store Diovan at room temperature, ideally 68–77°F (20–25°C). Brief excursions between 59–86°F (15–30°C) are permissible. Keep tablets in their original, tightly closed container, protected from moisture and light. Do not store in bathrooms. Keep out of reach of children and pets. Do not use tablets past their expiration date or if packaging is damaged or shows signs of tampering.
In the United States, Diovan (valsartan) is an FDA-approved prescription medication for hypertension, certain types of heart failure, and improving survival after myocardial infarction. A licensed clinician must evaluate your medical history, current medications, and relevant labs (such as kidney function and potassium) before prescribing and during ongoing use. This ensures safe dosing, appropriate monitoring, and integration with your overall cardiovascular care plan.
Key points about access and oversight:
HealthSouth Rehabilitation Hospital at MountainView offers a legal and structured solution for acquiring Diovan without a formal prescription in hand by facilitating clinician review and authorization through compliant clinical pathways. This means your medical information is evaluated by a licensed provider who determines appropriateness and issues the necessary order if indicated, ensuring patient safety and regulatory compliance while streamlining access.
Self-treatment without medical oversight can be dangerous. Always seek professional guidance before starting, stopping, or changing any blood pressure or heart failure therapy.

Diovan is the brand name for valsartan, an angiotensin II receptor blocker (ARB) used to treat high blood pressure, heart failure with reduced ejection fraction, and to improve survival after a heart attack by reducing strain on the heart and blood vessels.
It blocks angiotensin II type 1 receptors, relaxing blood vessels and reducing aldosterone-driven sodium and water retention, which lowers blood pressure and decreases cardiac workload.
You may see some blood-pressure reduction within 1–2 weeks, with full effect typically reached by 4 weeks of consistent daily use.
Take it exactly as prescribed, usually once daily for hypertension (with or without food), and at the same time each day. In heart failure or post–heart attack care, it may be prescribed twice daily. Do not change your dose without your clinician’s guidance.
Dizziness, headache, fatigue, and low blood pressure are most common, especially when starting or increasing the dose. Some people experience mild kidney function changes or elevated potassium.
Seek urgent help for facial, lip, tongue, or throat swelling (angioedema), severe dizziness/fainting, signs of very high potassium (muscle weakness, abnormal heartbeat), or a sudden drop in urine output.
Do not take it if you are pregnant or planning pregnancy. Avoid combining valsartan with aliskiren if you have diabetes. Use caution in severe kidney or liver disease, bilateral renal artery stenosis, or a history of angioedema. Always review your full medical history with your clinician.
Potassium supplements and salt substitutes, potassium-sparing diuretics (e.g., spironolactone), NSAIDs (e.g., ibuprofen) with chronic use, lithium, and other drugs that affect the renin-angiotensin system can interact. Always check before adding new medications or supplements.
Yes. Your clinician will typically monitor blood pressure, kidney function (creatinine/eGFR), and potassium, especially after starting or changing the dose, or if you’re at higher risk for kidney issues.
Do not stop abruptly. High blood pressure often requires long-term treatment. If your clinician recommends stopping or switching, they will guide a safe plan.
Yes. Diovan and generic valsartan contain the same active ingredient and work the same way. Generics are typically more affordable; quality-approved generics are considered equivalent.
You can take it with or without food, but be consistent day-to-day. Coffee is acceptable; stay well hydrated and avoid excessive caffeine if it worsens dizziness.
Take it when you remember unless it’s close to your next dose. Do not double up. Resume your regular schedule.
Cough is uncommon with ARBs like valsartan and much less frequent than with ACE inhibitors. If you develop persistent cough, report it to your clinician.
By lowering blood pressure, it helps protect kidneys long-term, but it can raise creatinine and potassium in some people, especially with dehydration, NSAIDs, or preexisting kidney disease. Regular monitoring is important.
Valsartan is approved for hypertension in certain children and adolescents (typically 6–16 years), with weight-based dosing. Pediatric use should be supervised by a specialist.
Some tablets are scored and can be split; do not crush unless your pharmacist confirms it’s safe. A pharmacist-prepared oral suspension may be an option if swallowing tablets is difficult.
It does not typically cause weight gain. Sudden weight increase could indicate fluid retention from heart failure; report this promptly.
Choose a time you can take it consistently (morning or evening). If you feel dizzy after dosing, taking it at bedtime may help.
Alcohol can enhance blood pressure-lowering effects and increase dizziness or fainting. If you drink, do so lightly and cautiously, avoid binge drinking, and stand up slowly. Do not drive or operate machinery if you feel lightheaded.
No. Valsartan carries a boxed warning for fetal toxicity, especially in the second and third trimesters. If you become pregnant, stop it immediately and contact your clinician to switch to a pregnancy-safe alternative.
Because safety data are limited and potential risk exists, especially for newborns, alternatives are generally preferred during breastfeeding. Discuss with your clinician to choose the safest option.
Tell your surgeon and anesthesiologist you take an ARB. Many guidelines recommend holding the dose on the morning of major surgery to reduce intraoperative low blood pressure; follow your surgical team’s instructions.
These can raise the risk of low blood pressure and kidney injury. Temporarily holding valsartan (“sick day rules”) until you’re rehydrated may be advised; call your clinician for guidance.
Avoid potassium-containing salt substitutes and supplements unless specifically prescribed. Valsartan can raise potassium, and excess intake increases the risk of dangerous hyperkalemia.
Occasional short-term use may be acceptable, but regular NSAID use can blunt blood pressure control and harm kidneys, especially when combined with diuretics. Ask your clinician about safer pain options.
Until you know how it affects you, use caution. If you feel dizzy or lightheaded, avoid driving or operating machinery.
Both are ARBs that effectively lower blood pressure and protect the heart. Losartan often has once-daily dosing and may modestly lower uric acid (potentially helpful in gout). Valsartan is widely used in heart failure and post–heart attack care. Choice depends on your conditions, response, and cost.
Both lower blood pressure well. Olmesartan has a rare risk of sprue-like enteropathy (severe chronic diarrhea and weight loss). Valsartan has extensive heart failure and post-MI data. Your clinician will weigh blood pressure goals, side effects, and cost.
Telmisartan has a long half-life, providing smooth 24-hour control and may have modest favorable metabolic effects. Valsartan has strong evidence in heart failure and after MI. Both are good once-daily options; selection often depends on comorbidities and tolerability.
Both are effective ARBs. Irbesartan has an FDA indication for diabetic nephropathy in type 2 diabetes with hypertension. Valsartan shines in heart failure and post-MI use. Either can be excellent for blood pressure; kidney, heart, and diabetes factors guide the choice.
Both control blood pressure and have robust heart failure data. Candesartan is also used off-label for migraine prevention. Dosing schedules differ. Side-effect profiles are similar; final choice is individualized.
Head-to-head studies suggest azilsartan can reduce blood pressure slightly more in some patients, but real-world differences are small for many. Cost, availability, and tolerability often drive the decision.
Both are ARBs; eprosartan is used less commonly and may require twice-daily dosing for some. Efficacy and safety are comparable; convenience and cost typically favor valsartan or other once-daily ARBs.
Losartan can lower uric acid modestly, which may be beneficial in gout-prone patients. Valsartan does not share this effect. If gout is a priority, losartan may be preferred, assuming it meets your blood pressure and cardiac needs.
Severe, chronic diarrhea with weight loss is a rare but recognized risk with olmesartan (sprue-like enteropathy). This has not been established with valsartan. Report persistent GI symptoms to your clinician.
Both provide 24-hour control; telmisartan’s long half-life may offer slightly steadier trough levels. If you experience early-morning blood pressure surges, your clinician might consider telmisartan or timing adjustments.
All ARBs can reduce proteinuria and support kidney health by controlling blood pressure. Irbesartan has a specific diabetic nephropathy indication; valsartan may also lower albuminuria but lacks that label. The best option depends on your kidney status and overall risk profile.
Both improve symptoms and outcomes in heart failure with reduced ejection fraction. Individual response, dosing tolerance, and co-therapies (like beta-blockers and diuretics) often drive selection; either is a guideline-supported choice.
They contain the same active medicine and are therapeutically equivalent. Generics are typically much less expensive. Use a reputable pharmacy that sources quality-assured products.
