Diovan 80mg Valsartan Tablets 28s

Diovan 80mg Valsartan Tablets 28s is a prescription cardiovascular medicine containing valsartan 80mg in each film-coated tablet. Valsartan belongs to a group of medicines known as angiotensin II receptor blockers, commonly abbreviated as ARBs.

Diovan is used to treat hypertension, commonly known as high blood pressure. It may also be prescribed for selected adults with heart failure or following a recent myocardial infarction when clinically appropriate.

Diovan should only be supplied and used according to a valid prescription, the approved product information and the patient’s individual treatment plan.

Diovan 80mg Valsartan Product Information

What Is Diovan 80mg Used For?

Diovan 80mg may be prescribed for selected adult patients with the following cardiovascular conditions.

Hypertension

Diovan is used to treat hypertension, commonly known as high blood pressure. Lowering and controlling blood pressure helps reduce the strain placed on the heart and blood vessels.

High blood pressure frequently causes no noticeable symptoms. Patients should continue treatment and attend scheduled blood-pressure reviews even when they feel well.

Heart Failure

Valsartan may be prescribed for selected adults with heart failure as part of an overall treatment plan. The doctor will consider the patient’s symptoms, heart function, kidney function, blood pressure and other heart medicines before prescribing Diovan.

Following a Recent Myocardial Infarction

Diovan may also be prescribed following a recent myocardial infarction, commonly known as a heart attack, in clinically stable patients with signs of left ventricular failure or left ventricular systolic dysfunction.

Use after a myocardial infarction requires careful medical supervision, dose titration and monitoring of kidney function and blood pressure.

How Diovan Works

Angiotensin II is a naturally occurring substance that causes blood vessels to tighten and can promote sodium retention.

Valsartan selectively blocks the action of angiotensin II at the AT₁ receptor. This helps blood vessels relax, supports a reduction in blood pressure and reduces the cardiovascular effects of excessive angiotensin II activity.

Diovan does not contain a diuretic. It contains valsartan as a single active ingredient.

How to Take Diovan 80mg

• Take Diovan exactly as prescribed by the treating doctor.
• Swallow the tablet with water.
• Diovan may be taken with or without food.
• Take each prescribed dose at approximately the same time each day.
• Do not increase, reduce or stop treatment without medical advice.
• Do not take a double dose to compensate for a missed dose.
• Continue any recommended diet, physical activity and blood-pressure monitoring plan.

The referenced professional product information lists 80mg once daily as a recommended dose for adult hypertension. However, the prescribed dose may differ according to the indication, blood-pressure response, kidney function, liver function, hydration status and other medicines.

The score line on the tablet is intended to make the tablet easier to break for swallowing. It is not intended to divide the tablet into equal doses.

Monitoring During Treatment

A doctor may monitor the following before and during valsartan treatment:

• Blood pressure
• Kidney function
• Blood potassium levels
• Other electrolyte levels when clinically appropriate
• Signs of dehydration or excessive blood-pressure reduction
• Heart-failure symptoms where applicable

Monitoring may be particularly important for older adults, patients with kidney impairment, patients taking diuretics and those using other medicines that affect the renin-angiotensin system.

Important Safety Information

• Diovan is a prescription medicine and should not be shared with another person.
• Diovan must not be used during pregnancy.
• Inform the doctor immediately if pregnancy occurs or is suspected during treatment.
• Tell the prescriber about kidney disease, liver disease, biliary obstruction or previous angioedema.
• Tell the doctor if vomiting, diarrhoea, heavy sweating or reduced fluid intake causes significant dehydration.
• Rise slowly from sitting or lying positions if dizziness occurs.
• Do not drive or operate machinery if dizziness, weakness or reduced alertness is present.
• Do not use potassium supplements or potassium-containing salt substitutes unless advised by a healthcare professional.
• Attend scheduled blood tests and medical reviews.

Who Should Not Take Diovan?

Diovan may be contraindicated or unsuitable for patients with certain conditions. These include:

• Known allergy to valsartan or another ingredient in the tablet
• Pregnancy
• Severe liver impairment
• Liver cirrhosis or biliary obstruction
• Severe kidney impairment or dialysis, according to the approved product information
• Certain combinations involving aliskiren in patients with type 2 diabetes or impaired kidney function

The treating doctor should review the patient’s complete medical history and medication list before starting or changing valsartan treatment.

Low Blood Pressure and Dehydration

Valsartan can cause symptomatic low blood pressure, particularly in patients who are significantly dehydrated or depleted of sodium.

The risk may increase in patients taking high-dose diuretics or experiencing:

• Severe vomiting or diarrhoea
• Heavy sweating
• Reduced fluid intake
• Prolonged illness
• Excessive fluid loss

Symptoms may include dizziness, faintness, weakness, blurred vision or fainting. Contact a healthcare professional when symptoms are persistent or severe.

Kidney Function and Potassium Levels

Medicines that affect the renin-angiotensin system can change kidney function and blood potassium levels in susceptible patients.

Additional monitoring may be needed for patients who:

• Have kidney impairment
• Have heart failure
• Have narrowing of the kidney arteries
• Are dehydrated
• Take potassium supplements
• Use potassium-sparing diuretics
• Use non-steroidal anti-inflammatory medicines regularly
• Use another medicine that acts on the renin-angiotensin system

Possible symptoms of high potassium may include muscle weakness, unusual tiredness, tingling sensations or an irregular heartbeat. High potassium may also occur without noticeable symptoms and may only be detected through a blood test.

Angioedema Warning

Angioedema has been reported in patients treated with valsartan. This may involve swelling of the face, lips, tongue, throat or airway.

Stop taking the medicine and seek urgent medical attention if swelling, difficulty breathing or difficulty swallowing occurs. Diovan should not be restarted after valsartan-associated angioedema unless specifically directed by an appropriate medical specialist.

Possible Side Effects

Not everyone experiences side effects. Possible effects associated with valsartan include:

• Dizziness or light-headedness
• Low blood pressure
• Postural dizziness when standing
• Tiredness or weakness
• Headache
• Cough
• Abdominal discomfort
• Nausea or diarrhoea
• Increased blood potassium
• Changes in kidney-function test results

Side effects may differ according to the indication, dose, concurrent medicines and the patient’s underlying medical condition.

Serious Symptoms Requiring Medical Attention

Seek prompt or urgent medical attention for symptoms including:

• Swelling of the face, lips, tongue or throat
• Difficulty breathing or swallowing
• Fainting or severe dizziness
• Very low urine output
• Severe weakness or an irregular heartbeat
• A severe, blistering or widespread skin reaction
• Rapid worsening of heart-failure symptoms
• Another severe or unexpected reaction

Medicine Interactions

Tell the doctor and pharmacist about all prescription medicines, non-prescription products, traditional medicines and supplements being used.

Products requiring particular consideration include:

• ACE inhibitors, other ARBs or aliskiren: combined renin-angiotensin system blockade may increase the risk of low blood pressure, high potassium and impaired kidney function.
• Potassium supplements: blood potassium may increase.
• Potassium-containing salt substitutes: these may increase potassium levels.
• Potassium-sparing diuretics: closer potassium and kidney-function monitoring may be required.
• Non-steroidal anti-inflammatory medicines: medicines such as ibuprofen, diclofenac and selective COX-2 inhibitors may reduce the antihypertensive effect and increase kidney risk in susceptible patients.
• Lithium: valsartan may increase lithium concentrations and the risk of lithium toxicity.
• Diuretics and other blood-pressure medicines: combined use may increase the likelihood of low blood pressure.
• Rifampicin, ciclosporin or ritonavir: these medicines may affect valsartan exposure and require professional review.

Do not start, stop or change another medicine without consulting the treating doctor or pharmacist.

Pregnancy and Breastfeeding

Diovan must not be used during pregnancy. Medicines that act directly on the renin-angiotensin system may cause serious injury or death to a developing baby.

Patients who are pregnant, planning a pregnancy or think they may be pregnant should contact their doctor immediately. If pregnancy is detected during treatment, Diovan should be discontinued as soon as possible under medical direction and replaced with a suitable alternative.

It is not known whether valsartan passes into human breast milk. The referenced professional product information advises against using Diovan while breastfeeding. A doctor should recommend an appropriate alternative treatment where necessary.

Use in Children and Adolescents

The referenced Novartis professional product information states that the safety and effectiveness of Diovan have not been established in patients below 18 years old.

Paediatric approvals may differ between countries. Diovan should therefore only be supplied to a child or adolescent when specifically prescribed under the applicable Malaysian product information.
