Buy Viridal Duo online in the UK

You can Buy Viridal (Alprostadil) online from Oxford Online Pharmacy for men to treat erectile dysfunction (ED).

Viridal injections come in 10mcg, 20mcg, and 40 mcg doses. They help you get and keep an erection for sexual performance. Available with a prescription from the online doctor service.

What is Viridal Duo?

Viridal Duo contains the active ingredient Alprostadil, which belongs to a class of medications called vasodilators. [1]

Before using the Viridal Duo starter pack, a medical professional must show you how to use the injections. You need this training before you can use them at home

  • To get an erection
  • To maintain an erection

Viridal Duo comes in a glass cartridge with two chambers.

Alprostadil (al-PROS-ta-dil) is in one chamber, while sodium chloride solution is in the other.

These are combined to create an injection-ready solution for intracavernosal injection (injecting into the shaft of the penis). [2]

How does Viridal work?

The alprostadil injection works by widening blood vessels and increasing blood flow to the penis.

Erections happen because of blood flow. The blood vessels in the penis need to expand and let in more blood to cause and maintain an erection.

The erection process

The penis's blood vessels enlarge and fill with blood when a man is sexually aroused due to nerve signals. This causes the penis to become hard by filling the corpora cavernosa, two chambers in the penis.

Health of blood vessels

The blood arteries must be healthy and able to transport enough blood for this process to function. A restricted flow of blood or injury to the blood vessels might make it difficult to achieve or sustain an erection. [3]

How long does Viridal Duo last?

An erection can happen 10 to 15 minutes after injecting Viridal Duo into the penis. It usually lasts for about an hour.

If you have an erection that lasts more than 4 hours (priapism), go to hospital right away.

Is Viridal Duo right for me?

Viridal Duo injections must only be used by men over the age of 18 who suffer from erectile dysfunction.

This medicine should never be used by women or children.

If you haven't tried any treatments for erectile dysfunction, we recommend starting with one of our first-line treatments. You can try Viagra (Sildenafil) or Cialis (Tadalafil) tablets. You could even try our ED starter pack which contains 3 main ED tablets.

If you cannot take tablets for any reason, you might try topical treatments. Vitaros cream (Alprostadil) is one option. Another option is a non-prescription treatment called Eroxon Stimgel.

Viridal Duo can interact with some medications. Tell your doctor about any medicines you are taking. This is important before using this ED injection in the UK.

Trustpilot

How to use Viridal Duo (Alprostadil) (10mcg, 20mcg, 40mcg)

Viridal should be injected into the shaft of the penis at least 10-15 minutes before you want to have sex. Sexual stimulation is not necessary to produce an erection with this medicine.

Most men need 10 to 20 micrograms for each injection. Always follow your doctor's dosage instructions on the label. You must not use more than 40 micrograms in one injection.

Before using the Viridal Duo starter pack, a medical professional must show you how to use Viridal Duo injections.

You must always double check the dose you are taking and follow the instructions given to you by your prescribing doctor.

You shouldn’t use Viridal more than once in 24 hours or more frequently than 2 - 3 times a week. If you use more Viridal than you should, this runs the risk of severe side effects.

You must be evaluated by your GP every 3 months to ensure you are getting the best results from this medicine. They will also monitor its effectiveness and whether you require a dose increase.

How do I inject my penis with Viridal Duo?

You will need:

  1. Easy-duo Injector
  2. Viridal cartridge (contains alprostadil and saline)
  3. Injection needle

These are all included in Viridal's box.

Important:  

  • Check the injector for damage before use
  • Only use with Viridal cartridges and BD Microfine needles
  • Needles and cartridges are not included

Steps:

1. Prepare the needle:

  • Check the needle’s seal and remove it
  • Attach the needle to the injector by screwing it on tightly

2. Prepare the cartridge:

  • Unscrew the plunger
  • Clean the cartridge tip with an alcohol swab
  • Insert the cartridge and screw the plunger back on

3. Mix the solution:

  • Hold the injector with the needle up
  • Push the plunger until the grey stoppers meet, dissolving the powder
  • Shake gently until the solution is clear

4. Remove air bubbles:

  • Remove both needle caps
  • Tap the injector to move bubbles upward, then push the plunger to release a drop of solution

5. Set the dose:

  • Move the plunger to the prescribed dose

6. Prepare injection site:

  • Clean the injection site and let it dry
  • Ensure the dose is correct and no air bubbles remain

7. Inject:

  • Hold the injector level and insert the needle straight into the site
  • Slowly inject the solution over 5–10 seconds

8. After injection:

  • Remove the needle
  • Apply pressure to the site if bleeding occurs

9. Wait for erection:

  • Expect an erection in 5–15 minutes, lasting about 1 hour
  • Contact your doctor if the erection lasts 2–4 hours, or seek help if it lasts longer than 4 hours

You can find the full Viridal Duo instructions on the patient information leaflet here.


Side effects of Viridal Duo (Alprostadil) (10mcg, 20mcg, 40mcg)

With any medication you take, there is always a risk of side effects. Some are more common than others, and often side effects may subside with regular usage of the medicine. If the side effects do not subside, you should report them to us, or your GP.

Very common:

  • Pain in the penis

Common:  

  • Burning sensation during injection which quickly gets better  
  • Pain at the site of injection  
  • Lumps at the site of injection or in your penis after long-term use
  • Spot-like bruising (blood spots under the skin) at the site of injection
  • Fluttering or vibrating feeling sensation due to uncontrollable muscle movement
  • Erections might occur more often and longer in duration
  • Bend or kink in the penis, especially after long-term use

Seek immediate medical help if you have any of the following symptoms:  

  • An painful erection that lasts for more than 4 hours
  • Serious allergic reactions which cause difficulty in breathing or dizziness
  • Skin reactions such as rashes and blistering

For a full list of side effects, please read the patient information leaflet.

Viridal Duo warnings

Do not combine Viridal Duo with any medications or muscle relaxants. These can increase the chance of having long erections lasting over four hours. You run the risk of endangering your health and aggravating your condition if you combine these types of medications.

We recommend that you avoid operating heavy equipment while using Viridal Duo. The drug may cause a sudden drop in blood pressure.

Frequently Asked Questions

Who should not use Viridal Duo?

Do not use Viridal Duo if you:

  • Are hypersensitive or allergic to any of the substances in Viridal Duo or any other medications that contain alprostadil.
  • Have any condition that makes you more susceptible to developing 'priapism,' such as sickle cell anaemia, leukaemia (blood cancer), multiple myeloma (bone cancer), or sickle cell carcinoma. When your penis continues to remain erect, this is a painful condition.
  • Have an implant in your penis.
  • You have had recent heart problems or a stroke and have been advised to not have sex.
  • Have scarring or deformity of the penis or foreskin.

      Before using Viridal Duo, it's crucial to inform the doctor about all of the medications you are currently taking because they may interfere with Viridal Duo.

Are injections better than pills for erectile dysfunction?

Injectable medicines cause an erection to occur on its own, without the requirement for sexual stimulation. In contrast, oral drugs like Viagra need a sexual stimulus in order to work. Drug absorption difficulties that may arise with some oral drugs are also resolved by injectables.

Do you need sexual stimulation with Viridal Duo?

No, Viridal injections help you to produce an erection without sexual stimulation required.

Do Viridal Duo injections hurt?

Due to the sensitivity of the place you are injecting the medicine you may feel some slight discomfort. Although, this discomfort is a common side effect, it is temporary. Many men only feel a sharp prick during the injection.

How long does Viridal Duo keep at room temperature?

It is safe to store Viridal at room temperature until its expirty date as long as the temperature doesn`t exceed 25 degrees. [4]

Is Viridal Duo available with a prescription online?

Yes, you can get a prescription for Viridal Duo online with the Oxford Online Pharmacy online doctor service.

Yes and no. Erectile dysfunction injections in the UK cannot be prescribed by NHS primary care for most men. They are only available for men who meet specific criteria. [5]

Are there Viridal Duo alternatives?

  • Caverject injections
  • Muse pellets
  • Vitaros cream

Viridal Duo vs Caverject: Which is better?

Both injectable medicines are used to treat erectile dysfunction and they also contain the same active ingredient, Alprostadil.

The only real difference between the two is that they have different brand names and are sold by different companies.

They both have different costs, Caverject starts from £29.99 for one pen, whereas Viridal Duo starts from £42.99 for two pens.*

Viridal duo contains two cartridges while Caverject only contains one which means that Viridal Duo is often better value for money.

*These prices are as of 21.11.24 and are subject to change.
