    Uses Of PROSTAGARD D 8MG CAPSULE

    Benefits of PROSTAGARD D 8MG CAPSULE

    • Relieves difficulty in urination
    • Improves urine flow and bladder control
    • Reduces frequent nighttime urination (nocturia)

    How PROSTAGARD D 8MG CAPSULE Works

    PROSTAGARD D 8MG CAPSULE is a combination of two active ingredients, Silodosin and Dutasteride, that work together to manage the symptoms of an enlarged prostate (Benign Prostatic Hyperplasia or BPH).

    • Silodosin: It is an alpha-blocker that relaxes the muscles in the prostate gland and bladder neck. By improving muscle relaxation, it helps enhance urine flow and reduces urinary symptoms such as frequent urination, difficulty starting urination, and incomplete bladder emptying.
    • Dutasteride: It is a 5-alpha reductase inhibitor that reduces the production of dihydrotestosterone (DHT), a hormone responsible for prostate growth. Over time, this helps shrink the prostate gland, alleviating pressure on the bladder and urethra.

    By combining these actions, Prostagard D 8mg Capsule effectively manages urinary symptoms of BPH, improving quality of life and reducing the risk of complications like urinary retention. For best results, it should be taken as prescribed by your doctor.

    FAQs About PROSTAGARD D 8MG CAPSULE

    Q: What is Prostagard D 8mg Capsule used for?

    A: Prostagard D 8mg Capsule is primarily used for managing benign prostatic hyperplasia (BPH), a condition characterized by an enlarged prostate. It combines silodosin (an alpha-blocker) and Dutasteride (a 5-alpha reductase inhibitor) to reduce prostate size and improve urinary flow, alleviating BPH symptoms like frequent urination and difficulty in urination.

    Q: What are Prostagard D 8mg Capsule benefits for prostate enlargement?

    A: Prostagard D 8mg Capsule helps reduce the size of an enlarged prostate, improving urinary symptoms associated with benign prostatic hyperplasia (BPH). It works by relaxing the muscles around the prostate and bladder and inhibiting the hormone responsible for prostate growth. This results in better urine flow, reduced urgency, and fewer nighttime bathroom visits.

    Q: How does Prostagard D 8mg Capsule work for BPH?

    A: Prostagard D 8mg Capsule works by combining two active ingredients: Dutasteride and Silodosin. Silodosin relaxes the muscles in the prostate and bladder, making it easier to urinate, while Dutasteride inhibits the enzyme that converts testosterone into dihydrotestosterone, the hormone responsible for prostate growth. Together, these actions relieve BPH symptoms and reduce the size of the prostate.

    Q: What are the common side effects of Prostagard D 8mg Capsule?

    A: Common side effects of Prostagard D 8mg Capsule include dizziness, especially when standing up quickly, fatigue, headaches, decreased libido, and sexual side effects like difficulty with ejaculation. Some men may also experience breast tenderness or enlargement due to Dutasteride.

    Q: Can Prostagard D 8mg Capsule cause sexual side effects and libido?

    A: Prostagard D 8mg Capsule may cause sexual side effects, including a reduction in libido (sexual desire) and changes in ejaculation, such as reduced semen volume. These side effects are primarily associated with Dutasteride, but they tend to improve over time or upon discontinuation of the medication.

    Q: What happens if you forgot a dose of Prostagard D 8mg Capsule?

    A: If you forget a dose of Prostagard D 8mg Capsule, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not take two doses at once to make up for a missed dose, as this can increase the risk of side effects.

    Q: Can Prostagard D 8mg Capsule be used for long-term?

    A: Prostagard D 8mg Capsule is generally considered safe for long-term use, especially for managing benign prostatic hyperplasia (BPH). However, it is important to have regular check-ups with your healthcare provider to monitor your response to the medication and adjust the dosage if necessary.

    Q: Is Prostagard D 8mg Capsule safe for elderly patients?

    A: Prostagard D 8mg Capsule can be used by elderly patients, but they may be more sensitive to the effects of the medication, particularly dizziness or fatigue. It is essential for older patients to start with the lowest effective dose and regularly monitor for any side effects. Always consult with a healthcare provider for appropriate adjustments.

    Q: Prostagard D 8mg Capsule vs Finasteride: Which is better for BPH?

    A: Both Prostagard D 8mg Capsule and Finasteride are used for managing BPH, but Prostagard D 8mg Capsule combines two medications: silodosin (for muscle relaxation) and Dutasteride (for inhibiting prostate growth). Finasteride is a single-drug therapy that also targets DHT.  Prostagard D 8mg Capsule may provide faster symptom relief by combining both mechanisms. Your healthcare provider can recommend the best treatment based on individual needs.

    Q: Can I buy Prostagard D 8mg Capsule online?

    A: Yes, simply upload your prescription during checkout to comply with pharmacy requirements.

    Q: How is my Prostagard D 8mg Capsule order delivered?

    Q: Who can guide me about the right usage?

    A: For any queries, consult your healthcare provider or our licensed pharmacist through live chat.
