Cardene Capsules is an FDA-approved treatment widely prescribed to manage conditions such as chest pain and hypertension. As a calcium channel blocker (CCB), Cardene works by relaxing the blood vessels, which facilitates lowering blood pressure and alleviating chest pain associated with restricted blood flow to the heart. This medication can also influence heart rate, further promoting its therapeutic effects. Originally introduced under a brand name, Cardene is now also available in its generic form, allowing broader accessibility. It comes in doses of 20mg, 30mg, and 45mg, providing flexibility in addressing individual patient needs and conditions. These capsules are also available in sustained-release forms of 30mg, 45mg, and 60mg. So, if you need to buy Cardene with coupon for hypertension and chest pain, you need a doctor’s prescription first.
Cardene is an FDA-approved medication that contains nicardipine hydrochloride, a calcium channel blocker primarily prescribed to manage high blood pressure (hypertension) and relieve angina (chest pain). It functions by relaxing the heart muscles and widening blood vessels, improving blood flow & reducing the heart’s workload. Cardene is available in the form of capsules of 20mg, 30mg, and 45mg strengths.
The usual dosage ranges from two to four times daily, depending on the patient’s condition and response to treatment. It can be taken with or without food, though food may slightly affect absorption. Cardene is prescribed for adults with hypertension or angina, as determined by a healthcare provider. Possible side effects of Cardene Capsules include dizziness, headache, nausea, and flushing, which typically resolve with continued use. Seek medical attention if severe reactions like a rapid heartbeat, breathing difficulties, or swelling occur.
Before starting treatment, tell your doctor or healthcare provider about any existing heart, liver, or kidney issues. If a dose of Cardene is missed, take it as soon as you remember unless the next dose is near; avoid doubling doses. In case of Cardene overdose, contact emergency services immediately. Store Cardene at room temperature, away from moisture and heat. Follow your healthcare provider’s instructions closely for safe and effective use. Consult your doctor before starting, adjusting, or discontinuing the medication.

Nicardipine Hydrochloride, commonly known by the brand name Cardene, is a medication classified as a calcium channel blocker (CCB). This pharmaceutical works by inhibiting the influx of calcium ions into the smooth muscle cells lining the blood vessels. As a result, it causes these vessels to relax and dilate, which leads to a reduction in blood pressure. This relaxation effect not only helps lower blood pressure but also alleviates chest pain, particularly in angina cases where the heart muscles are deprived of adequate oxygen due to constricted coronary arteries. Through its action, nicardipine hydrochloride improves blood flow, which can be beneficial for patients experiencing cardiovascular issues.
Common side effects of Cardene: Similar to other medications, Cardene can cause certain temporary side effects in some people using it, which usually resolve on their own without any medical intervention within a few days or weeks. If they persist or become worrisome, talk to your doctor. If you are concerned about any risks associated with the use of Cardene, talk to your doctor before use. Common Cardene side effects include:
Mild side effects of Cardene: Cardene can cause certain mild side effects in some users, which are not typically serious and can be resolved on their own without medical intervention. This list does not include all possible side effects, and there may be other risks, too. Talk to your doctor for more details. However, it is important to mention that your doctor has prescribed you Cardene Capsules for hypertension treatment after deciding that its benefits justify the risks associated with its use. Mild side effects of Cardene may include:
Serious side effects of Cardene: Rarely, Cardene Capsules can lead to severe symptoms in some patients using it for long-term blood pressure management. These symptoms require immediate medical assistance and can cause serious complications, which can be potentially fatal if not treated properly. If you experience any of the symptoms given below, immediately call your doctor or 911. Regular monitoring and doctor visits are essential to make sure the medication is not causing you unfavorable symptoms. Severe Cardene symptoms include:
[Note: Remember, this above-mentioned list may not cover all possible side effects of Cardene. It is better to consult your healthcare giver for medical advice about side effects.]
There are certain warnings for Cardene Capsules that you should consider while using this product for blood pressure management. For safe and effective use of the tablets, you should use them exactly as directed and avoid using them for longer than recommended or in large quantities. Key points of the warnings include:
Allergies and Ingredient Sensitivity: When starting treatment with Cardene Capsules, it’s essential to thoroughly discuss your allergy history with your healthcare provider. This discussion should specifically include any known allergies to nicardipine hydrochloride, which is the active ingredient in Cardene. If you’ve previously had adverse reactions to medications similar to nicardipine hydrochloride, it’s important to alert your healthcare provider to these as well. Furthermore, Cardene Capsules may contain several inactive ingredients that, while not having therapeutic effects, could potentially cause allergic reactions or other health problems. To ensure that you have all the necessary information about these components and how they might affect you, please consult with your pharmacist, who can provide detailed insights and guidance.
Blood Pressure: Due to its mechanism of action, where Cardene reduces peripheral resistance, it is highly recommended that blood pressure be closely monitored during the initial administration and subsequent titration of the medication. Cardene functions as a calcium channel blocker and, similar to other drugs in this category, it may sometimes lead to symptomatic hypotension, or abnormally low blood pressure (BP) that may cause dizziness or fainting. Particular caution should be exercised when administering Cardene to patients who have recently experienced an acute cerebral infarction (stroke caused by a blood clot) or hemorrhage (stroke caused by bleeding). Maintaining stable blood pressure in these patients is crucial because drastic drops in blood pressure could worsen their condition or lead to other serious complications. Therefore, managing and monitoring systemic blood pressure is essential to avoid inducing hypotensive episodes in these vulnerable patients.
Similar to other medications, Cardene Capsules also come with certain precautions that you should keep in mind before using them for hypertension treatment. To ensure that this medication is suitable for you to use, you should tell your doctor about your complete medical and family history and inform them about all medications you currently use or plan to use to avoid potential interactions with Cardene. Precautions include:
Use in Patients with Impaired Hepatic Function: Cardene undergoes extensive biotransformation primarily in the liver, which serves as the central organ for metabolizing substances in the body. Additionally, Cardene is affected by first-pass metabolism, a process where the liver metabolizes a significant portion of the medication before it enters the bloodstream. Consequently, patients with compromised liver function or decreased hepatic blood flow should use Cardene cautiously. This caution is essential because impaired liver function can significantly alter the drug’s metabolism, potentially leading to adverse effects. Furthermore, the half-life of Cardene, which is the time it takes for half of the drug to be eliminated from the body, is prolonged to about 19 hours in these patients compared to those with normal liver function. This prolongation and increased exposure may enhance the risk of toxicity and necessitate careful monitoring and potential dosage adjustments.
Various Health Conditions: Cardene should not be used if you have certain health conditions, particularly structural heart problems like aortic stenosis. Always discuss your complete medical history with your healthcare provider before starting this medication, paying special attention to any past issues related to kidney disease.
Surgical Considerations: If you are scheduled for any type of surgery, including dental procedures, make sure to inform your doctor or dentist that you are taking Cardene. This precaution helps manage any potential interactions or complications during the surgery.
Impact on Daily Life Considerations: Nicardipine Hydrochloride, the active component of Cardene, can cause dizziness, affecting your ability to drive, operate machinery, or engage in any activity that demands sharp alertness. You should not perform these activities until you are certain of your reaction to the medication. Additionally, it is highly advisable to limit your intake of alcoholic beverages as they can exacerbate dizziness.
Use During Pregnancy and Breastfeeding: During pregnancy, Cardene should only be used when absolutely necessary, after a thorough discussion of the risks and benefits with your doctor. The impact of this medication on an unborn child is not entirely known, making it essential to use this drug under direct medical advice. It is also unknown whether Cardene passes into breast milk, so breastfeeding mothers can consult their healthcare giver to understand the potential risks and make an informed decision.
Patients with Aortic Stenosis: Cardene is contraindicated in patients suffering from advanced aortic stenosis. The mechanism of action of Cardene involves the reduction of afterload, which is the pressure the heart must work against to eject blood. In the context of advanced aortic stenosis, lowering the diastolic pressure can lead to a paradoxical situation where the myocardial oxygen balance is further compromised rather than improved. Therefore, using Cardene in such patients could worsen their condition by exacerbating the existing obstruction in the heart’s aortic valve.
[Note: If you missed a dose of Cardene & are unsure about when to take the next dose, immediately consult your doctor or healthcare giver.]
If you suspect an overdose of Cardene, it may lead to symptoms such as systemic hypotension (low blood pressure), bradycardia (slow heart rate), which can follow an initial period of tachycardia (fast heart rate), and progressive atrioventricular conduction block, affecting the heart rhythm. Immediately contact or call a poison control center or seek emergency medical attention. Residents in the US may call their local poison control center for guidance.
[Note: If you consumed more than the recommended Cardene dose, get medical help immediately, or you can call the Poison Helpline at 1-800-222-1222.]
Following proper Cardene Capsules storage guidelines help maintain their effectiveness. Keep them in their original container, in a cool, dark & dry place out of direct exposure to excess heat, sunlight & moisture. Make sure they are out of reach of children and pets. Check the product packaging for storage guidelines, or refer to the storage instructions below.
[Note: Discuss with your healthcare professional or doctor about the proper disposal of any unused Cardene Capsules and any questions you may have regarding their storage.]
Cardene Capsules can interact with other medications, which may change how they work or increase the risk of side effects. Understanding these potential interactions is essential for safe and effective treatment. Tell your physician or healthcare provider about all the drugs you currently use or plan to use, including all prescription medicines, over-the-counter drugs, herbs, and vitamin supplements. This helps you and your doctor identify and manage drug interactions. Some potential drug interactions of Cardene may include:
Beta-Blockers: In controlled clinical trials, adrenergic beta-receptor blockers have frequently been used in conjunction with Cardene. Patients have generally tolerated this combination well. However, healthcare providers should monitor patients to ensure no adverse effects arise from this concurrent therapy.
Cimetidine: The administration of cimetidine alongside Cardene has been shown to increase the plasma levels of Cardene. Due to this interaction, it is crucial for healthcare professionals to closely monitor patients receiving both medications, to ensure that Cardene levels remain within a therapeutic range and to adjust dosages as necessary.
Digoxin: While some calcium channel blockers can elevate the blood concentrations of digitalis-based drugs, Cardene typically does not influence digoxin plasma levels. Nevertheless, checking serum digoxin levels after initiating combined therapy with Cardene is recommended to ensure that they stay within safe limits.
Fentanyl Anesthesia: Severe hypotension has been observed during fentanyl anesthesia when used in conjunction with beta-blockers and calcium channel blockers. Although clinical studies with Cardene have not demonstrated similar interactions, there is a potential risk. It is advised that an increased volume of circulating fluids be prepared and available during such anesthesia procedures to mitigate the risk of severe hypotension.
Cyclosporine: When Cardene is administered with cyclosporine, there is a notable increase in plasma cyclosporine levels. It is essential for healthcare providers to monitor these levels closely in patients undergoing such combined treatment. Adjustments to the dosage of cyclosporine should be made accordingly to maintain appropriate therapeutic levels and prevent toxicity.
[Note: This is not a complete list, & there could be other drugs that interact with Cardene. Make sure to tell your doctor or healthcare giver about any prescription, over-the-counter medicines, and herbal products you’re currently taking.]
Cardene Capsules should be avoided at or near meal times, as consuming food can lead to potential interactions. Specifically, certain foods may interact with the medication, altering its effectiveness or side effects. Additionally, the concurrent use of alcohol or tobacco with Cardene Capsules is discouraged as these substances can interact with the Cardene, potentially leading to adverse effects. This medication also has some disease interactions, which users should be aware of before using it. These include:
While Cardene for blood pressure management is an effective treatment, there may be some contraindications or limitations to using the medications, which causes people to look for alternatives to Cardene Capsules. While there are many effective alternative treatment options available on the market, patients should not use them without consulting their doctor or healthcare provider. Some of the most effective alternatives to Cardene may include:
[Note: Your doctor will determine the best treatment option for you, including whether Cardene or an alternative medication is appropriate. Do not use any alternative medications without consulting your healthcare provider, as self-medicating could lead to serious side effects.]
