HOW SILDENAFIL WORKS

Mechanism of Action

Sildenafil belongs to a class of medications called PDE5 inhibitors. It works by relaxing blood vessels and increasing blood flow to the penis during sexual stimulation.

Blocks PDE5 Enzyme

Sildenafil inhibits phosphodiesterase type 5 (PDE5), an enzyme that breaks down cGMP - a molecule that relaxes smooth muscle in blood vessel walls.

Increases Blood Flow

By preserving cGMP, sildenafil allows blood vessels in the penis to relax and widen, improving blood flow needed for an erection.

Requires Sexual Stimulation

Sildenafil does not cause automatic erections. Sexual arousal is still needed to initiate the natural process that sildenafil enhances.

FREQUENTLY ASKED QUESTIONS

Common Questions About Viagra and Sildenafil

What is the difference between Viagra and sildenafil?

Viagra is the brand name for sildenafil, manufactured by Pfizer. Generic sildenafil contains the same active ingredient and works identically but is made by other pharmaceutical companies. The main difference is price - generic sildenafil is significantly cheaper while being equally effective and safe.

How do I get Viagra or sildenafil in Ireland?

In Ireland, Viagra and sildenafil are prescription-only medications. You need a prescription from a registered doctor. With GetYourGP, you can request a prescription online - complete a health questionnaire, and if appropriate, one of our Irish-registered GPs will issue a prescription sent directly to your chosen pharmacy.

How quickly does sildenafil work?

Sildenafil typically starts working within 30-60 minutes of taking it. For best results, take it on an empty stomach or after a light meal, as fatty foods can delay its effects. The medication remains effective for 4-6 hours, though this does not mean you will have an erection for this entire time - sexual stimulation is still required.

What dosage of sildenafil should I take?

The recommended starting dose is 50mg, taken approximately one hour before sexual activity. Depending on effectiveness and tolerability, your GP may adjust this to 25mg or 100mg. Never take more than 100mg in a 24-hour period. Your GP will recommend the most appropriate dose for you.

What are the common side effects of sildenafil?

Common side effects include headache, facial flushing, nasal congestion, indigestion, and dizziness. These are usually mild and temporary. Less common but more serious side effects include sudden vision or hearing changes - if you experience these, stop taking the medication and seek medical help immediately.

Who should not take Viagra or sildenafil?

Sildenafil is not suitable for everyone. You should not take it if you use nitrate medications (for angina), have severe heart or liver problems, recently had a stroke or heart attack, have low blood pressure, or have certain rare inherited eye conditions. Always complete the health questionnaire honestly so our GP can assess your suitability.

Can I take sildenafil with alcohol?

While moderate alcohol consumption is unlikely to cause problems, excessive alcohol can reduce the effectiveness of sildenafil and increase the risk of side effects like dizziness and low blood pressure. For best results, limit alcohol intake when using this medication.

How much does Viagra cost in Ireland?

With GetYourGP, generic sildenafil prescriptions start from EUR29 (prescription fee only - medication cost varies by pharmacy). Branded Viagra prescriptions start from EUR49. These prices include the GP review and electronic prescription. Generic sildenafil is equally effective and significantly more affordable than branded Viagra.

Is it safe to buy Viagra online in Ireland?

Buying from legitimate online GP services like GetYourGP is safe - all our GPs are Irish Medical Council registered and prescriptions are sent to licensed Irish pharmacies. However, buying Viagra without a prescription from unregulated websites is dangerous - these products may be counterfeit, contain wrong dosages, or harmful ingredients.

How long can I take sildenafil for?

Sildenafil can be taken long-term as needed for erectile dysfunction. There is no maximum duration of use. However, if you find the medication is becoming less effective or you need it more frequently, consult your GP as this may indicate changes in your underlying health that should be investigated.
