Viagra Professional is a prescription‑only PDE5 inhibitor that contains the active ingredient sildenafil citrate. It’s designed to treat erectile dysfunction (ED) by boosting blood flow to the penis after sexual stimulation. The drug typically works within 30-60 minutes, lasts about 4‑5 hours, and can be taken with or without food, though a heavy high‑fat meal may delay onset.
Understanding the Mechanism: PDE5 Inhibitors
Phosphodiesterase‑5 (PDE5) inhibitors are a class of medicines that block the enzyme PDE5, which normally breaks down cyclic guanosine monophosphate (cGMP). By preserving cGMP, the smooth muscle in the penile arteries relaxes, allowing more blood to fill the corpora cavernosa and produce an erection. Sildenafil, tadalafil, vardenafil and avanafil all belong to this class, but they differ in pharmacokinetics and side‑effect profiles.
Prescription Alternatives Compared
When doctors weigh options, they usually consider four main ED medications:
- Cialis (generic tadalafil) - long‑acting, up to 36hours, taken daily or as needed.
- Levitra (generic vardenafil) - similar onset to sildenafil but a slightly shorter window (4‑5hours).
- Stendra (generic avanafil) - fastest onset (as quick as 15minutes) and a clean side‑effect record.
- Viagra Professional - the benchmark for duration and reliability, often the first drug tried.
Non‑Prescription Options
Some men explore over‑the‑counter or lifestyle routes before or alongside a prescription:
- L‑arginine - an amino‑acid that may boost nitric oxide, the natural precursor of cGMP.
- Panax ginseng - a herbal adaptogen with modest evidence for improving erectile quality.
- Pelvic floor exercises - strengthen muscles that support erection, recommended by many urologists.
- Weight loss & aerobic activity - address vascular causes of ED, often lowering the need for medication.
Side‑Effect Landscape
All PDE5 inhibitors share a core set of possible reactions-headache, flushing, nasal congestion, visual disturbances-but the frequency varies. For instance, sildenafil is more likely to cause mild color vision changes, while tadalafil can lead to muscle aches. Non‑prescription supplements may interact with nitrates or antihypertensives, so medical advice is still wise.
| Medication | Typical Dose | Onset | Duration | Food Interaction | Common Side Effects |
|---|---|---|---|---|---|
| Viagra Professional (Sildenafil) | 50mg (adjust 25‑100mg) | 30‑60min | 4‑5hrs | High‑fat meals may delay | Headache, flushing, mild visual tint |
| Cialis (Tadalafil) | 10mg (adjust 5‑20mg) | 15‑30min | Up to 36hrs | Minimal | Back pain, indigestion, headache |
| Levitra (Vardenafil) | 10mg (adjust 5‑20mg) | 30‑60min | 4‑5hrs | Fat slows absorption | Flushing, dizziness, nausea |
| Stendra (Avanafil) | 100mg (adjust 50‑200mg) | 15‑30min | 6‑12hrs | Negligible | Headache, mild rash, nasal congestion |
Choosing the Right Option for Your Life
Everyone’s situation is different. Below is a quick guide that matches common priorities with the drug that ticks the most boxes:
- Spontaneous intimacy - Stendra because it works in as little as 15minutes. \n
- Weekend‑long flexibility - Cialis due to its “the weekend pill” 36‑hour window.
- Cost‑conscious first‑line - Viagra Professional because generic sildenafil is widely available and covered by many insurers.
- Minimal side‑effects - Stendra or low‑dose Tadalafil if back‑pain worries you.

Frequently Asked Questions
Can I take Viagra Professional and alcohol together?
A moderate drink (one‑two units) usually isn’t a problem, but heavy drinking can worsen side effects like dizziness and lower blood pressure, making the erection less reliable.
Is a daily low‑dose Cialis better than an as‑needed Viagra?
Daily tadalafil (2.5‑5mg) provides a constant level of the drug, which can help men who want spontaneous sex without planning. It may cost a bit more month‑to‑month, but eliminates timing anxiety.
Do herbal supplements work as a substitute for prescription pills?
Evidence is mixed. L‑arginine and ginseng can modestly improve blood flow, but they rarely produce the firm, reliable erection that PDE5 inhibitors deliver. They’re best used alongside lifestyle changes, not as a sole therapy.
What should I do if I experience a prolonged erection?
A erection lasting more than four hours (priapism) is a medical emergency. Seek immediate care - the longer it persists, the higher the risk of permanent tissue damage.
Can I switch between different PDE5 inhibitors?
Yes, many doctors rotate drugs to find the best balance of effectiveness and tolerability. Always have a short wash‑out period (usually 24‑48hours) and discuss any side‑effects before changing.
