Drug Therapies
Oral medications like Viagra®, Cialis®, and Levitra® are some of the most well-known options for managing ED. These medications work by increasing blood flow to the penis in response to sexual stimulation.
Advantages
- Easy to use and widely available.
- Effective for many men when taken 30-60 minutes before sexual activity.
Considerations
- May cause side effects, including headaches, flushing, upset stomach, and visual changes.
- Not effective for all cases (approximately 30% of men may not respond).

Injections
For those who do not respond to oral medications, injectable drugs can create an erection by increasing blood flow.
Advantages
- Quick results (5-20 minutes) and high effectiveness.
Considerations
- May cause scarring or prolonged erections, and some men find injections uncomfortable or inconvenient.
