Indications
Nisoldipine is prescribed, either alone or in conjunction with other medications, for the management of elevated blood pressure (hypertension). Its role in reducing high blood pressure aids in the prevention of strokes, heart attacks, and kidney issues. Classified as a calcium channel blocker, nisoldipine operates by promoting the relaxation of blood vessels, facilitating smoother blood flow.
Uses and Dosage
Take this medication orally on an empty stomach or with a low-fat meal, following your doctor’s instructions, typically once daily. Avoid ingestion within 1 hour before or 2 hours after consuming a high-fat meal to minimize the risk of increased side effects.
Ingest the tablets whole; refrain from crushing or chewing them, as breaking them down may result in the sudden release of the entire drug, heightening the likelihood of side effects.
Various sustained-action forms of this medication are available in different strengths. Confirm with your doctor or pharmacist that you are using the correct dose and form. Do not switch to a different strength or form without consulting your healthcare professional first.
While using this medication, steer clear of grapefruit and grapefruit juice unless approved by your doctor or pharmacist, as they can elevate the likelihood of side effects. Seek additional information from your healthcare provider.
The dosage is determined based on your medical condition and how you respond to treatment. Your doctor may gradually increase your dose, so adhere to their instructions meticulously.
To optimize its effectiveness, take this medication consistently at the same time each day. Continue taking it even if you feel well, as individuals with high blood pressure often don’t experience symptoms.
Inform your doctor if your condition doesn’t improve or worsens, such as if your routine blood pressure readings persist or elevate.
