Product Description

🔹 Product Overview
Hyponat-O 15 mg Tablet is a prescription medicine containing Tolvaptan 15 mg. It belongs to a class of medicines known as vasopressin receptor antagonists and is used primarily in the management of low sodium levels in the blood (hyponatremia) associated with certain medical conditions.
Tolvaptan works by helping the kidneys remove excess free water from the body while retaining sodium, which can help increase the concentration of sodium in the blood.

🔹 Key Uses
Hyponat-O 15 mg may be prescribed for:
Treatment of certain cases of hyponatremia
Hyponatremia associated with syndrome of inappropriate antidiuretic hormone secretion (SIADH)
Low sodium levels associated with certain conditions such as heart failure or other disorders involving excess water retention
Correction of low blood sodium under appropriate medical supervision

🔹 Composition
Active ingredient: Tolvaptan 15 mg
Dosage form: Tablet
Route of administration: Oral
Therapeutic class: Vasopressin receptor antagonist
Pharmacological action: Promotes free-water excretion
Marketer: Zydus Healthcare Ltd.

🔹 How It Works
Hyponat-O 15 mg contains tolvaptan, which blocks the action of vasopressin (antidiuretic hormone) at V2 receptors in the kidneys.
This reduces the kidneys' reabsorption of water and increases the amount of water passed in the urine. By removing excess water while retaining sodium, the medicine can help increase blood sodium concentration in appropriate patients.

🔹 Key Benefits
Helps increase low blood sodium levels when appropriately prescribed
Promotes removal of excess water from the body
May be useful in patients with SIADH-related hyponatremia
Helps restore fluid and electrolyte balance under medical supervision
Oral tablet formulation for convenient administration

🔹 Dosage and Administration
Take Hyponat-O 15 mg exactly as prescribed by your doctor.
Swallow the tablet whole with water.
It may be taken with or without food.
Do not crush, chew, or break the tablet unless specifically instructed by your healthcare professional.
The dose and duration depend on the patient's sodium levels, medical condition, kidney and liver function, and response to treatment.
Maintain access to water and drink when thirsty as directed by your healthcare professional.
Do not change the dose or duration yourself.
Important: Tolvaptan treatment can cause blood sodium levels to rise too quickly. Sodium levels therefore require appropriate medical monitoring, particularly when treatment is initiated or restarted.

🔹 Possible Side Effects
Commonly reported side effects may include:
Increased thirst
Dry mouth
Frequent urination
Increased nighttime urination
Nausea
Constipation
Increased blood creatinine
Increased potassium levels
Changes in blood pressure
Excessive water loss can lead to dehydration, particularly if adequate fluids are not consumed.

🔹 Precautions
Hyponat-O 15 mg should be used only under medical supervision.
Blood sodium levels should be monitored during treatment.
Tell your doctor if you have kidney or liver problems.
Do not use it if you are unable to recognize or respond to thirst.
Tell your doctor if you have difficulty passing urine or are severely dehydrated.
Tolvaptan can cause sodium levels to increase too rapidly. A rapid correction of hyponatremia can cause serious neurological complications, including osmotic demyelination syndrome.
Liver function may require monitoring during treatment, particularly with longer-term use.
Contact your doctor promptly if you develop yellowing of the skin or eyes, dark urine, unusual weakness, or abdominal symptoms.
Do not self-treat low sodium levels with this medicine.
