How does Sildenafil Citrate (Viagra) work? Understanding the science behind stronger, lasting erections

Viagra, known generically as sildenafil citrate, is among the most researched and prescribed treatments for erectile dysfunction (ED) both in Canada and worldwide. But how does it actually help achieve and sustain erections?

The active ingredient, sildenafil citrate, works by enhancing blood flow to the penis during sexual stimulation. Specifically, it inhibits an enzyme called phosphodiesterase type 5 (PDE5), which can otherwise restrict blood flow. By blocking PDE5, sildenafil citrate relaxes blood vessels and increases circulation, enabling a natural response to sexual arousal.

Viagra does not cause spontaneous erections—it only works in combination with sexual stimulation. Effects typically begin within 30–60 minutes of taking the tablet and can last up to 4–6 hours. This window provides flexibility for intimacy, helping you regain sexual confidence on your terms.

Choosing your dose: What strength of sildenafil is right for me?

Selecting the appropriate dosage of sildenafil is an important decision, best made in consultation with a Canadian healthcare professional. Viagra is available in three dosages:

• 25mg: Lowest strength, often used for men who are older, have certain medical conditions, or who experience more significant side effects at higher doses.
• 50mg: The standard starting dose for most men with ED. Provides a balance between effectiveness and tolerability.
• 100mg: Maximum recommended single dose. Reserved for men who need a stronger effect and have not experienced satisfactory results from the lower doses.

The table below summarizes the key factors to consider when selecting your dose:

Viagra (Sildenafil) Dosage Comparison

Dosage	Who It’s For	Typical Scenarios	Possible Side Effects
25mg	Older adults, men with kidney/liver issues, those sensitive to medication	First-time users, caution with certain medications (e.g., nitrates)	Mild, less common
50mg	Most men with ED	Standard starting dose, balanced efficacy	Possible mild to moderate side effects
100mg	Men who need a stronger response	After lower doses have been tried	Increased likelihood and severity

Note: Never take more than one dose (maximum 100mg) per 24-hour period. Always follow your prescriber’s advice as listed on your pharmacy label or consultation summary.

Precautions and warnings: What Canadians need to know before using sildenafil

As with all prescription medications, sildenafil citrate is not suitable for everyone. Before you order sildenafil or buy Viagra online, consider the following precautions to ensure safe and effective treatment:

• Do not take sildenafil with nitrates: Combining with nitrate medications (often used for chest pain) can cause dangerous drops in blood pressure. This combination is strictly contraindicated.
• Cardiovascular concerns: Men with significant heart or liver conditions should only use sildenafil under strict medical supervision. Seek advice if you have a history of heart attack, stroke, or arrhythmias.
• Potential side effects: Common side effects include headache, facial flushing, indigestion, nasal congestion, and mild visual changes (such as blue-tinted vision). Most side effects are mild and temporary. Severe reactions are rare.
• Drug interactions: Always disclose a full list of your medications to your Canadian pharmacist or prescriber during your online consultation. Certain drugs, including alpha-blockers, antifungal or antibiotic medications, may interact with sildenafil.
• Avoid excess alcohol: Drinking heavily before taking Viagra can reduce effectiveness and increase side effects.
• Not for women or minors: Viagra is only intended for use by adult men with a prescription, as approved by Health Canada.
• Emergency symptoms: Seek medical assistance if you experience chest pain, sudden vision or hearing loss, or an erection lasting longer than 4 hours (priapism).
• Health Canada standards: Ensure your tablets are sourced from a licensed Canadian pharmacy and registered in the Drug Product Database (DPD). Avoid unregulated sources.
