Sildenafil, the active ingredient in Viagra, works by increasing blood flow to the penis, aiding in achieving an erection. However, it’s not a universal solution and has specific limitations.
Side Effects
Common side effects include headache, facial flushing, nasal congestion, and visual disturbances. Less frequent but more serious side effects can include heart problems, hearing loss, and vision loss. Consult your doctor immediately if you experience any concerning symptoms.
Ineffectiveness
Sildenafil’s efficacy depends on several factors, including the underlying cause of erectile dysfunction. It may not be effective for men with certain medical conditions, such as severe heart disease or uncontrolled high blood pressure. Additionally, psychological factors like stress and anxiety can interfere with its effectiveness.
Interactions
Sildenafil interacts with various medications. Taking it with nitrates, for example, can cause a dangerous drop in blood pressure. Always inform your doctor of all medications, supplements, and herbal remedies you’re taking before starting sildenafil.
Dosage and Administration
The correct dosage varies depending on individual needs and medical history. Your doctor will determine the appropriate dose, which should not be exceeded. It’s taken orally, usually about an hour before sexual activity.
Contraindications
| Severe heart disease | Generally contraindicated |
| Uncontrolled high blood pressure | Generally contraindicated |
| Recent stroke or heart attack | Generally contraindicated |
| Retinitis pigmentosa | Generally contraindicated |
Alternative Treatments
If sildenafil proves ineffective or unsuitable, other treatment options exist. These include alternative oral medications, injections, vacuum erection devices, and penile implants. Your doctor can discuss these alternatives and help you find the best approach for your individual needs. Open communication with your doctor is crucial for managing erectile dysfunction effectively.
