Why is this medication prescribed?

Cardura (generic name: doxazosin) is a medication primarily prescribed to treat hypertension (high blood pressure) and benign prostatic hyperplasia (BPH). Here’s how it is used and prescribed:

• Hypertension: Cardura helps lower blood pressure by relaxing blood vessels, making it easier for blood to flow.
• Benign Prostatic Hyperplasia (BPH): It is also used to improve the symptoms of BPH, a condition where the prostate gland enlarges, causing difficulty in urination. Cardura relaxes the muscles in the prostate and bladder neck, making it easier to urinate.

How should this medicine be used?

How should Cardura be used:

• Dosage: The dosage of Cardura will vary depending on the condition being treated and the individual’s response to the medication. It is typically started at a low dose and gradually increased under medical supervision to achieve the desired effect.
• Administration: Cardura is usually taken orally once daily, either with or without food. It’s important to take it at the same time each day to maintain consistent levels in your bloodstream.
• Follow Medical Advice: Always follow your doctor’s instructions carefully regarding dosage and usage. Do not increase or decrease the dose or stop taking Cardura without consulting your doctor, as sudden changes can affect your condition adversely.
• Monitoring: Regular blood pressure checks and monitoring of symptoms are often recommended while taking Cardura to ensure it is working effectively and to watch for any side effects.
• Missed Doses: If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to catch up.
• Side Effects: Like all medications, Cardura can cause side effects. Common side effects may include dizziness, lightheadedness, fatigue, and headache. More serious but rare side effects may include fainting, irregular heartbeat, or shortness of breath. If you experience any concerning symptoms, notify your doctor promptly.

Always ensure you understand the specific instructions provided by your healthcare provider regarding the use of Cardura, and do not hesitate to ask questions if anything is unclear or if you have concerns about the medication.

Other uses for this medicine

• Management of Raynaud’s Disease: Cardura may be used to improve blood flow in patients with Raynaud’s disease, a condition where certain areas of the body usually fingers and toes, feel numb and cold in response to cold temperatures or stress.
• Management of Congestive Heart Failure: In some cases, Cardura may be used as part of the treatment for congestive heart failure, a condition where the heart cannot pump enough blood to meet the body’s needs.

What special precautions should I follow?

Special Precautions for Cardura:

• Orthostatic Hypotension: Cardura can cause a sudden drop in blood pressure when standing up, especially during the first few days of treatment or when the dosage is increased. To minimize this risk, take Cardura at bedtime initially, which helps reduce the likelihood of dizziness or fainting upon standing.
• Avoid Alcohol and Other Medications: Alcohol and certain medications (like other blood pressure medications, alpha-blockers, or phosphodiesterase-5 inhibitors used for erectile dysfunction) can enhance the blood pressure-lowering effects of Cardura. It’s important to avoid alcohol and inform your doctor about all medications you are taking before starting Cardura.
• Driving and Operating Machinery: Cardura may cause dizziness or drowsiness, especially at the beginning of treatment or with dosage adjustments. Avoid driving or operating machinery until you know how Cardura affects you.
• Monitoring: Regular monitoring of blood pressure is necessary, especially during initial treatment and dosage adjustments. This helps ensure that Cardura is effectively lowering blood pressure without causing side effects.
• Surgery Precautions: If you are scheduled for cataract surgery or another eye procedure, inform your eye surgeon that you are taking Cardura or have taken it in the past. Cardura can interfere with the dilation of the pupil during these procedures.
• Allergic Reactions: If you have a known allergy to doxazosin or similar medications (like prazosin), inform your doctor before starting Cardura.

Always follow your doctor’s instructions and ask any questions you may have about special precautions or potential interactions with Cardura. This ensures safe and effective use of the medication tailored to your individual health needs.

What special dietary instructions should I follow?

There are no specific dietary restrictions associated with Cardura. However, it’s generally recommended to follow a balanced diet low in salt (sodium) to help manage hypertension effectively. If you have any specific dietary concerns or conditions, such as kidney disease, your doctor may provide personalized dietary recommendations.

What should I do if I forget a dose?

• If you miss a dose of Cardura, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule.
• Do not double the dose to catch up. Taking two doses close together can increase the risk of side effects and will not improve your condition faster.
