4. How is DBL Papaverine Hydrochloride Injection given?
How much is given
Your doctor will decide what dose of papaverine you will receive. This depends on
your medical condition and whether or not you are taking any other medicines.
How DBL Papaverine Hydrochloride Injection is given
A doctor or nurse will show you how to do the injection for at least the first time.
If you will be self-administering papaverine your doctor will provide you with proper
training and instruction to ensure that administration related injuries do not occur.
It is important that you follow your doctor's instructions at all times. If you are
not certain about the way this medicine is given please contact your doctor; this
leaflet is only intended to remind you about the instructions your doctor has already
given you.
Always use a new syringe and needle for each injection. A 13 mm 27 to 30 gauge needle
is recommended.
If the needle is bent at any time, do not use it for injecting papaverine and do not
attempt to straighten it before injecting papaverine. A bent or restraightened needle
may be more likely to break. Needle breakage with a portion of the needle remaining
in the penis has been reported and in some cases requires hospitalisation and surgical
removal.
Do not use papaverine if the ampoule is damaged or if the solution looks cloudy, coloured,
or has particles in it.
Stretch the penis out across the thigh. If you are uncircumcised the foreskin must
be pulled back before you inject papaverine. Clean the injection area with an alcohol
swab.
Papaverine is injected directly into the base of the penis on the left or right-hand
side. It is given as a slow injection over 1 to 2 minutes. Papaverine should not be
injected just under the skin or into the midline or lower part of the penis.
After you have completed the injection, put pressure on the place of injection to
prevent bruising. Then massage your penis as instructed by your doctor. This helps
the medicine spread to all parts of the penis, so that it will work better.
Do not re-use or share needles or syringes.
Papaverine normally begins to work in about 10 minutes and the erection may persist
for one to several hours.

phone the Poisons Information Centre
(by calling
13 11 26), or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
Symptoms of an overdose may include nausea, vomiting, weakness, drowsiness, double
vision, rapid uncontrollable movements of the eyes, sweating, flushing, dizziness,
increased heart rate or priapism (a persistent painful erection of the penis that
does not reverse within four hours).
