« Viagra »: what it is and what your next step should be
Disclaimer: This article is for informational purposes only and does not replace professional medical advice, diagnosis, or treatment. Erectile dysfunction (ED) can have physical or psychological causes. Always consult a qualified healthcare professional before starting or changing any medication, including Viagra (sildenafil).
Viagra is the brand name for sildenafil, a medication used to treat erectile dysfunction (ED). If you’re searching for “Viagra for men,” “how sildenafil works,” or “ED treatment options,” you’re likely looking for clear next steps. Below is a practical, user‑journey guide: from first symptoms to what usually happens next.
3 typical scenarios
Scenario 1: Occasional difficulty getting or keeping an erection
Who/what is experienced: You sometimes struggle to achieve or maintain an erection, especially during stressful periods, after poor sleep, alcohol use, or performance anxiety.
What this might mean: Occasional ED is common and may be linked to stress, fatigue, relationship factors, or temporary health changes. It does not automatically mean a chronic condition. However, if it becomes frequent (more than 25% of attempts), it may suggest underlying erectile dysfunction.
What a doctor usually does:
- Asks about onset, frequency, and severity of symptoms.
- Reviews medications (some antidepressants, blood pressure drugs).
- Assesses lifestyle factors (smoking, alcohol, sleep, exercise).
- May recommend basic blood tests (glucose, lipids, testosterone).
In some cases, a doctor may discuss short-term use of a PDE5 inhibitor such as sildenafil. You can read more about related men’s health concerns in our men’s health resources.
Scenario 2: Persistent erectile dysfunction with cardiovascular risk factors
Who/what is experienced: You have ongoing ED and also high blood pressure, diabetes, obesity, or high cholesterol.
What this might mean: ED can be an early sign of cardiovascular disease. The blood vessels in the penis are smaller than coronary arteries, so erection problems may appear before heart symptoms. This does not confirm heart disease, but it warrants evaluation.
What a doctor usually does:
- Performs cardiovascular risk assessment.
- Orders blood tests (HbA1c, lipid panel).
- Measures blood pressure and BMI.
- Evaluates safety of sexual activity and ED medications.
If appropriate, sildenafil (Viagra) may be prescribed as directed by a doctor, provided you are not taking nitrates or certain heart medications. Lifestyle modification is often part of the plan.
Scenario 3: ED affecting confidence, relationships, or mental health
Who/what is experienced: You avoid intimacy due to fear of “failure,” feel anxious before sex, or notice tension in your relationship.
What this might mean: Psychological factors such as performance anxiety, depression, or stress can contribute to ED. Sometimes physical and psychological causes overlap.
What a doctor usually does:
- Screens for anxiety and depression.
- Explores relationship context.
- Determines whether morning or spontaneous erections are present (helps distinguish causes).
- May suggest counseling or sex therapy in addition to medication.
A combined approach—medical and psychological—often provides the best results. See our overview of treatment approaches for sexual health for broader context.
Decision tree: what should you do next?
- If ED happened once or twice during stress → then monitor, reduce alcohol, improve sleep, manage stress.
- If ED persists for 3+ months → then schedule a primary care or urology appointment.
- If you have diabetes, hypertension, or chest pain → then request cardiovascular evaluation before using ED medication.
- If you take nitrates (e.g., nitroglycerin) → then do not use sildenafil without explicit physician approval.
- If psychological stress is dominant → then consider counseling alongside medical assessment.
- If you are considering buying Viagra online → then ensure it is a licensed pharmacy and requires a prescription.
When to seek help urgently (red flags)
- Chest pain during sex: May indicate cardiac strain—seek immediate care.
- Priapism (erection lasting more than 4 hours): Requires emergency treatment to prevent permanent damage.
- Sudden vision or hearing loss after taking sildenafil: Rare but serious—stop medication and seek care.
- Severe dizziness or fainting: Possible dangerous blood pressure drop.
Approaches to treatment/management (overview of ED therapies)
Treatment depends on the cause. Options may include:
- PDE5 inhibitors: Sildenafil (Viagra), tadalafil, vardenafil—enhance blood flow to the penis. Used as prescribed by a doctor. They require sexual stimulation to work.
- Lifestyle modification: Weight loss, smoking cessation, exercise, improved sleep.
- Psychological therapy: Cognitive behavioral therapy (CBT), sex therapy.
- Hormone treatment: If clinically low testosterone is confirmed.
- Vacuum erection devices: Mechanical support option.
- Penile injections or implants: Considered in more severe or treatment-resistant cases.

Prevention: reducing the risk of erectile dysfunction
- Maintain cardiovascular health (control blood pressure, cholesterol).
- Exercise regularly (aerobic activity improves blood flow).
- Quit smoking.
- Limit excessive alcohol intake.
- Manage stress and mental health.
- Have regular health checkups after age 40—or earlier if risk factors exist.
| Method | Who it suits | Limitations/Risks |
|---|---|---|
| PDE5 inhibitors (e.g., sildenafil) | Men with diagnosed ED without nitrate use | Headache, flushing, interaction with nitrates |
| Lifestyle changes | All men, especially with metabolic risk factors | Requires long-term adherence |
| Psychotherapy | ED linked to anxiety, depression, relationship issues | May take time to see results |
| Hormone therapy | Men with confirmed low testosterone | Requires monitoring; not for normal levels |
| Devices/surgical options | Severe or refractory ED | Invasive; procedural risks |
