FAQs for Medicine?

Q1. What is the purpose of prescribing Sildohyp-4D?

For benign prostatic hyperplasia (BPH) presenting with symptoms such as diminished urinary stream and increased urinary frequency.

Q2. How does this differ from Sildohyp-4?

Sildohyp-4: Exclusive use of Silodosin for symptom alleviation

Sildohyp-4D: Silodosin + Dutasteride → alleviation of symptoms and reduction of prostate size

Q3. What is the duration required for it to become effective?

Silodosin: Provides relief within 2 to 6 hours

Dutasteride: Requires a period of 3 to 6 months for prostate size reduction

Q4. Does it induce any sexual side effects?

Yes, it is feasible:

Reduced sexual desire

Erectile dysfunction

Reduced semen production / retrograde ejaculation

Q5. Is this medication suitable for use by women?

No, exclusively designated for males.

Q6. Is it necessary to take it for the remainder of my life?

Long-term treatment is a standard approach in managing BPH.

Expert advice

• Consume after meals to mitigate vertigo.
• Dutasteride may require several months; maintain the treatment regimen even in the absence of rapid progress.
• Refrain from standing abruptly—risk of postural disequilibrium.
• Notify the ophthalmic surgeon prior to cataract surgery regarding silodosin to assess the risk of IFIS.
• Refrain from donating blood while currently taking dutasteride and for six months following cessation of the medication.
• Regular PSA screenings may be necessary; dutasteride reduces PSA levels by approximately 50%.
• Refrain from consuming alcohol, as it can exacerbate vertigo.

Side Effects

• Prevalent
• Reduced ejaculation
• Vertigo
• Nasal obstruction
• Reduced sexual desire
• Uncommon
• Impotence
• Exhaustion
• Breast tenderness and edema
• Headache
• Uncommon but Critical
• Profound hypotension
• Allergic response
• Alterations in temperament or symptoms of depression
• Prostate cancer risk (infrequent, minimal-grade elevation)
• Request medical assistance for severe symptoms.

How it works

• Silodosin at a dosage of 4 milligrams
• Blocks alpha-1A receptors on the prostate and bladder neck →
• Eases muscular tension
• Enhances urinary flow
• Decreases urgency, frequency, and exertion
• Dutasteride (0.5 milligrams)
• Inhibits the 5-alpha reductase enzyme, thereby decreasing DHT levels (a hormone responsible for prostate enlargement).
• Results in:
• Reduction of the prostate gland
• Decreased likelihood of future urinary retention
• Reduced requirement for prostate surgical procedures
• Combined Advantage:
• Immediate alleviation of symptoms coupled with sustained structural enhancement.

Medicine Interaction

Significant Interactions

• Ketoconazole, Itraconazole → Increased Silodosin levels
• Ritonavir → Increased side effects
• Other alpha-blockers (Tamsulosin) ⇒ significant blood pressure reduction
• Moderate Engagements
• BP medications → contributory syncope
• PDE5 inhibitors (Sildenafil, Tadalafil) ⇒ significant decrease in blood pressure
• Alcohol consumption exacerbates vertigo.
• Warfarin → Monitor INR
• Important Notice:
• Women should refrain from handling crushed or fractured tablets (due to the risk of dutasteride absorption).

How to use

• Dosage: One tablet once daily following meals.
• Swallow entirely with water; do not pulverize.
• Take it at the same time each day.
• In the event of a missed dose:
• Take it immediately upon recalling.
• Disregard if within proximity of the subsequent dose.
• Avoid administering a double dose.

Uses/Indications

• Benign Prostatic Hyperplasia (BPH)
• Diminished urinary stream
• Regular urination
• Nocturnal urination (nocturia)
• Partial bladder evacuation
• Prevention of sudden urinary retention
• Sustained reduction of prostate girth
