When oral treatments for Erectile Dysfunction (ED) such as sildenafil (Viagra) or tadalafil (Cialis) do not provide the desired results or are unsuitable due to medical conditions, doctors often recommend alternative routes. One of the most highly effective, second-line treatments available is Viridal Duo.
If you are exploring prescription options for ED, this guide explains exactly what Viridal Duo is, how it works, and what to expect when using it.
What is Viridal Duo (Alprostadil)?
Viridal Duo is a branded prescription medication used to treat erectile dysfunction in adult men. Its active ingredient is alprostadil, a synthetic version of a naturally occurring hormone in your body called Prostaglandin E1 (PGE1).https://curedpharmacy.com/products/viridal-alprostadil-duo
Unlike oral ED tablets that must be absorbed through the digestive tract and require natural sexual arousal to work, Viridal Duo is an intracavernosal injection meaning it is injected directly into the spongy tissue of the penis. Because the medication is delivered locally, it bypasses the digestive system entirely, resulting in rapid and highly reliable erections.
How Does Viridal Duo Work?
To understand how Viridal Duo helps you achieve an erection, it is helpful to know how the active ingredient operates.
Alprostadil acts as a vasodilator. When injected, it works directly on the blood vessels in the penis, causing the smooth muscles to relax and the arteries to widen (dilate). This rapid widening allows a significant surge of arterial blood to flow into the corpora cavernosa (the two expandable chambers in the penis), creating a firm erection.
One of the defining features of this medication is that it does not require sexual stimulation to produce an erection, unlike standard PDE5 inhibitor pills.
Fast-Acting Results and Duration
Because it is injected locally, the onset time is incredibly fast:
- Time to Erection: Most men will experience an erection within 5 to 15 minutes of administering the injection.
- Duration: When the correct dosage is found, the erection should last for approximately 1 hour, providing a predictable and natural window for intimacy.
Understanding Dosages and Preparation
Viridal Duo is typically available in three different strengths: 10mcg, 20mcg, and 40mcg. Your prescriber will start you on a very low dose and gradually increase it until you find the exact strength that provides an erection lasting no longer than one hour.
The Two-Chamber Cartridge System
The “Duo” in the name refers to the medication’s unique packaging. It comes in a specialised glass cartridge containing two separate chambers:
- One chamber holds the active alprostadil powder.
- The other holds a sodium chloride solution.
Using a reusable injector device, you push a plunger to break the seal between the chambers, mixing the liquid and powder to create the final injectable solution just before use.
How is Viridal Duo Administered?
CRITICAL NOTE: You must never attempt to use Viridal Duo for the first time on your own. A doctor or healthcare professional must physically demonstrate how to prepare the injector, set the correct dose, and properly inject the medication.
A general overview of the process involves:
- Preparation: Mixing the powder and solution within the two-chamber cartridge using the injector pen.
- Priming: Tapping out air bubbles and dialing in your exact prescribed dose.
- Injection: Cleaning the side of the penis (the base), and carefully inserting the fine needle straight in. It is important to alternate injection sites (left side vs. right side) with each use to prevent scar tissue formation.
- Compression: Applying pressure with a clean swab for a few minutes after the needle is withdrawn to prevent bruising.
Important Safety Precautions
While Viridal Duo is highly effective, it comes with strict usage guidelines:
- Frequency: Do not use the medication more than once in a 24-hour period, and no more than 2 to 3 times per week.
- Priapism Warning: If an erection persists for longer than 4 hours, you must seek emergency medical attention immediately. Prolonged erections can permanently damage penile tissue.
- Side Effects: Common localized side effects can include a mild aching or burning sensation in the penis, and minor bruising or spotting at the injection site.
- Who Should Avoid It: It is not suitable for men with a history of priapism, conditions like sickle cell anaemia or leukaemia, penile implants, or anatomical deformities of the penis (e.g., Peyronie’s disease).
Conclusion
For men who have not found success with oral PDE5 inhibitors, Viridal Duo represents a highly effective, fast-acting alternative. While the idea of penile injections can seem daunting initially, the auto-injector system and proper clinical training make it a manageable and life-changing solution for overcoming severe erectile dysfunction.
Always consult with a registered GP or regulated online pharmacy prescriber to see if Viridal Duo is the right next step for your sexual health.
