Abstract

Intracavernosal injections provide an effective therapy for men with erectile dysfunction who can not take oral agents or for whom oral agents are not effective. Determining the best initial dosage can be a challenge for health care providers. A literature review and 13 years of experience working with patients receiving intracavernosal injections provide the basis for the algorithm designed to provide guidance with the dosage and titration of the injection medications.

Introduction

Intracavernosal injection therapy is an effective therapy for men with erectile dysfunction (ED) who can not take oral agents or for whom oral agents are not effective. Initial dosing and dosage titration is typically individualized for each man, but there are general guidelines that can be followed. In caring for men who are beginning therapy with intracavernosal penile injections, the health care clinician is faced with many choices about starting dosages and titration of medications.

Injections are given with a 1 ml syringe with 1/2 or 5/8-inch length, and a 27 to 30-gauge needle. The injection may be given anywhere from the base of the penis to two-thirds of the way down the penile shaft at the 10 o'clock and 2 o'clock locations on the upper side of the penis away from the urethra and the head of the penis (see Figure 1). Injections are rotated within that area and the side of the injection is alternated with each injection. Many factors must be considered when determining a starting dose and titrating medication for patients. The goal of this treatment is to create an erection sufficient for sexual relations, while minimizing side effects such as pain or priapism.
