Get Injector Treatment Online

Injector contains alprostadil, a synthetic prostaglandin E1. When injected directly into the side of the penis, it relaxes smooth muscle and widens blood vessels, increasing blood flow and producing an erection typically within 5 to 20 minutes of administration.

Good candidates are adult men who have already been diagnosed with erectile dysfunction, have been trained by a clinician on proper self-injection technique, and have previously used alprostadil without serious adverse reactions such as prolonged erection (priapism) or significant pain.

Alprostadil should be injected into the corpus cavernosum on the side of the penis, alternating sides with each use. Use the dose your doctor prescribed, and never inject more than once in a 24-hour period or more than three times per week. Seek emergency care immediately if an erection lasts more than four hours.

The most common side effects include pain or mild discomfort at the injection site, prolonged erection (priapism), and, with long-term use, formation of fibrous tissue (fibrosis) at the injection site. Systemic side effects such as dizziness or low blood pressure are possible but less common.

Alprostadil can interact with antihypertensive medications and may cause additive blood pressure lowering. You should disclose all current medications to your Doctronic physician during your refill evaluation so they can confirm that alprostadil remains appropriate and safe for you.

Oral PDE5 inhibitors such as sildenafil and tadalafil require sexual stimulation to work and act systemically. Alprostadil is injected locally and produces an erection regardless of sexual stimulation, making it a useful option for men who do not respond to or cannot take oral PDE5 inhibitors.
