Erectile Dysfunction

Caverject

Caverject is an injection of alprostadil that’s used to treat erectile dysfunction. It’s injected directly into the penis and is recommended for men who’ve already tried first-line treatments such as sildenafil but haven’t had success with them.

Alprostadil works in a similar way to the naturally occurring hormone, prostaglandin. It helps the blood vessels to dilate and therefore makes it easier for blood to flow into the penis and maintain an erection.

Caverject tends to work within 15 minutes of the injection being administered, and the effects last for around 30-60 minutes. It’s advised that if you still have an erection after an hour, to seek urgent medical advice.

Caverject isn’t a first-line treatment for erectile dysfunction, and you should always visit your GP before trying it for the first time as you’ll need to be shown how to administer the medication. As it’s in the form of an injection, using it without being shown how to might cause damage to your penis.


Please note: This treatment can only be prescribed to males. If you’re ordering this from a female’s account, your order will be declined by our doctors for patient safety reasons. Please make sure that all orders come from the account of the patient who will be taking this medication.

What is Caverject?

Caverject is a medicine that’s used to treat erectile dysfunction (or impotence) in men. It contains alprostadil, which is similar to the natural hormone prostaglandin. Alprostadil helps to dilate the blood vessels to help blood flow more easily into the penis.

Unlike most other treatments for erectile dysfunction, Caverject is injected into the base of the penis rather than being taken orally. This might put a few people off trying the treatment, but it’s never prescribed as a first-line solution to ED; it’s only ever given after oral medicines and other treatments have failed to achieve or maintain an erection.

Caverject comes in two slightly different forms; as vials, and as a dual chamber. They’re set up slightly differently but both are injected directly into the penis.

What is erectile dysfunction?

Erectile dysfunction is when a man struggles to achieve or maintain an erection, and therefore finds it difficult to have sex. It’s often seen as an embarrassing condition and something that isn’t widely talked about, but it’s surprisingly common. Whilst it’s more likely in men over the age of 40, young males can also suffer with erectile dysfunction, and it can have several causes such as:

Diabetes
Obesity
Anxiety
Depression
Smoking
Being over 40
Hypertension
Some medicines
Drug use
Alcohol use
Relationship issues
Injuries
Cancer
Cardiovascular disease
Hyperlipidemia

Not being able to achieve an erection doesn’t mean that you aren’t sexually aroused, though this could be one cause. Most men find that with medication, they’re able to achieve an erection and have sex easily.

Can I use Caverject?

Caverject isn’t the most commonly prescribed treatment for erectile dysfunction, so you won’t be given the medication unless you’ve already tried drugs such as sildenafil (Viagra) or tadalafil (Cialis) first. Depending on your GP and cause of your erectile dysfunction, you might even need to try talking therapies before being prescribed Caverject. If you’ve already tried the above solutions and they haven’t worked for you, you might be a good candidate for the alprostadil injection. However, there are still people that need to avoid the medication or speak to their GP before having it prescribed. These people include those who:

Allergic to Caverject
Have sickle cell anaemia
Have leukaemia
Have multiple myeloma
Have a penis implant
Are advised against having sex
Have a scarred or curved penis
Have a tight foreskin
Have a lung, chest or heart disorder
Have a history of mental illness/addiction
Have history of a mini stroke
Are at risk of cardiovascular disease
Are at risk of a stroke

There are also some medicines that might interact with Caverjact or some of its ingredients. This can mean that one of the medications won’t work as well, or it increases the risk of side effects if they’re used together. If you take any of the medicines on the following list, please talk to your doctor or pharmacist before starting on Caverject as you might need an alternative drug.

  • Antihypertensives (medicines for high blood pressure)
  • Sympathomimetics (medicines for respiratory and heart problems)
  • Vasodilative agents (drugs that can dilate blood vessels)
  • Other medicines for erectile dysfunction such as sildenafil, tadalafil or others
  • Anticoagulants (blood thinners) such as warfarin as this can increase your risk of bleeding at the injection site.

If it’s your first time trying Caverject, you’ll need to see your own doctor first as they will need to show you how to administer the injection properly. This will help you to avoid damaging your penis or injecting it into the wrong area.

What are the side effects of Caverject?

Like most medicines, using Caverject can give you other symptoms which are known as side effects. Not everyone experiences them, and some people only find that they fell them mildly, but here are some of the most commonly reported symptoms associated with Caverject:

Pain in penis
Prolonged erections
Muscle spasms
Bruising or scarring with long-term use
Curved penis with long-term use
Other penis problems
Injection site reactions
Painful erections
Swelling or foreskin or head of penis
Irritated penis
Numb penis
Warm penis
Bleeding penis
Lumps in the testicles
Pelvic pain
Weakness
Sweating
Nausea
Thrush
Common cold
Change in blood pressure
Change in heart rhythm
Fainting or collapse
Shalllow breathing

More side effects are available in the patient information leaflet that comes with your order. It’s important to familiarise yourself with these so that you know if your symptoms are serious or not. If any side effects bother you to an alarming degree, please seek urgent medical attention and stop using Caverject.

You should also seek advice quickly if your erection lasts more than an hour.

How long does Caverject take to work?

Caverject starts working within 5-15 minutes of the injection being administered. However, you should usually wait 10-30 minutes before you attempt to have sex.

Erections achieved with the help of caverject usually last between 30 minutes to an hour.

How often can I use Caverject?

Caverject shouldn’t be used more than 3 times a week, and you should leave at least 24 hours between doses. If you feel like you need to use Caverject more than this, make an appointment with your GP to discuss alternative treatments which might allow you to have sex more often.

How do I use Caverject?

As caverject is an injection, we advise that you visit your GP to be shown exactly how to use it. Instructions are also available in the patient information leaflet. These are specific to each form, so make sure you have the right leaflet for either the dual chamber injection or the vials.

Generally, Caverject is injected into the base of the penis, but your nurse or doctor will be able to tell you more accurately than any website can.

A half-inch needle is generally recommended for administration, and you should never use a needle more than once.

Each Caverject injection is single-use only, so please dispose of them accordingly once they’ve been used.

How much Caverject should I use?

You should only ever use one injection at a time. Your doctor will determine which dose is best for you. They’ll usually prescribe the lowest effective dose for you to make sure you can achieve an erection but also avoid any adverse effects.

Does Caverject hurt?

It may do at first, but many men report that this gets better as you get used to using it. It should be noted that your penis may bleed slightly at the injection site when you first start using it, and this can increase the risk of transmission of various STIs. You should always wear a condom if you’re unsure of yours or your partner’s sexual health status.

Are there any alternatives?

There are many different medications available for erectile dysfunction, though if you’re using Caverject, you’ve most likely already tried a few of them. Some of the most common ones include:

You can also get other forms of alprostadil such as a pellet or topical cream. These can be bought online from reputable websites that display the MHRA logo and registered pharmacy number.

At Doctor4U, you’ll always need to fill in a short patient questionnaire to make sure the medication is suitable for you before it’s prescribed. Make sure you know which ED medication is best for you before you order through us.
