Different people need different amounts of Caverject to treat erectile dysfunction. Your doctor will advise on the right dose for you and monitor you regularly to check how it is working. Consult the Patient Information Leaflet for detailed instructions before you buy Caverject.

• The starting dose is 1.25 - 2.5 micrograms.
• Most men find that a dose of 5 - 20 micrograms is right for them, however, some men may require a higher dose. To minimise the risk of prolonged painful erection, your doctor will select the lowest effective dose. You should never use more than 60 micrograms.
• If Caverject is being used to find the reason for your erectile dysfunction, the dose will be 5 - 20 micrograms.
• Do not use Caverject more than once in 24 hours or more than three times in a week.
• Change the exact place and side of the penis that you inject Caverject each time you use it.
• For single use only; any unused Caverject should be discarded.
• Do not use Caverject if the injection is cloudy or contains particles.
• When you have mixed the Caverject Powder with the solution, use it straight away. Do not keep it to use later on.
• It will take a little while for your erection to come on after the injection. Usually, your erection should not last longer than an hour.* If your erection lasts longer than four hours you should seek medical advice

If the dose that has been prescribed for you does not work well enough, you should contact your local doctor or our GMC registered doctor for further advice.

After use, ensure that the syringe, vial and needles are disposed of in a closed, puncture-resistant container, such as a sharps bin. Ask your doctor or pharmacist for instructions on how to properly dispose of the container after use.

*Disclaimer: Individual results may vary.

The active ingredient in Caverject is alprostadil. Caverject 10 micrograms also contains the other ingredients: lactose monohydrate, sodium citrate, α-cyclodextrine, hydrochloric acid and sodium hydroxide.

The syringe contains benzyl alcohol (8.4 mg/ml) and water for injections. The antiseptic pads are soaked in isopropyl alcohol.

Do not use Caverject if you:

• Are allergic (hypersensitive) to Caverject or any other medicines containing alprostadil or any of the other ingredients of Caverject
• Have sickle cell anaemia (a blood disease), leukaemia (cancer of the blood), multiple myeloma (bone cancer) or any other problem which increases the risk of getting “priapism”. This is a painful condition when your penis continues to remain erect
• Have an implant in your penis
• Have a condition (such as severe heart disease) in which sexual activity should be avoided
• Have a penis which is scarred or not straight
• Have a tight foreskin.

Tell your doctor before using Caverject if you:

• Have a lung, chest or heart disorder (in these cases you also should engage in sexual activity with caution)
• Have a history of mental illness or addiction
• Have had a mini-stroke (transient ischaemic attack)

Caverject will not protect you or your partner from sexually transmitted diseases like AIDS, herpes and gonorrhoea. Injection of Caverject can start a small amount of bleeding where the needle enters. This could increase the risk of transmission of such diseases. Condoms can protect against sexually transmitted diseases. If you need advice about contraception or ‘safe sex’ speak to your doctor or contact your local Family Planning Clinic.

Tell your doctor if you are taking any of the following medicines before you start using Caverject:

• Medicines used for treating high blood pressure (antihypertensives)
• Medicines used for respiratory and heart disease (sympathomimetics)
• Medicines that widen blood vessels (vasodilative agents)
• Other medicines for erectile dysfunction such as sildenafil or papaverine
• Medicines to thin your blood such as warfarin or heparin, as you might bleed more
• when you do the injection.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Caverject can be used by couples wishing to conceive and with a partner who is pregnant or breast-feeding. It will not protect your partner from pregnancy, so you should use a reliable contraceptive if appropriate.

 Always consult the Patient Information leaflet before use.
