How does Sidena (Sildenafil) work?

Sidena works by relaxing the blood vessels in the penis, allowing more blood to flow into it when sexually aroused. This increased blood flow helps to achieve and maintain an erection.

How should I take Sidena?

The recommended dose of Sidena is 50mg (1 tablet) once daily as needed, taken approximately one hour before sexual activity. Swallow the tablet whole with water, and do not take more than 1 tablet daily.

Is Sidena as Effective as Viagra?

Yes, Sidena is as effective as Viagra because they both contain the same active ingredient, sildenafil. The effectiveness of these medications depends on individual responses, but they are medically equivalent.

Can I use Viagra and Sidena at the same time?

No, you should not use Viagra and Sidena at the same time, as both contain the same active ingredient, sildenafil. Taking more than one sildenafil product can result in an overdose.

How do I know if Sidena is right for me?

We offer Sidena both online and in-store for adult men (18 years and older) experiencing difficulties with their erections. It is crucial to consult with a healthcare professional before taking Sidena to ensure its suitability based on individual medical history and current medications, as well as to receive personalised dosage recommendations. Count on Phelans Pharmacy for dependable assistance and convenient access to Sidena. Your health and well-being are our primary concerns. Please note that Sidena is not intended for use by women, individuals under 18 years of age, or those without erectile dysfunction.

Can I use Sidena if I have underlying medical conditions?

Not all individuals with underlying medical conditions can safely use Sidena. If you have a history of severe heart disease, stroke, liver disease, kidney disease, or certain eye conditions, among others, Sidena might not be suitable for you. Always consult your doctor before starting Sidena.

This is why you’ll be asked a few straightforward questions about your health before we supply you with Sidena tablets.

What are the side effects of Sidena?

Most men find Sidena effective and do not experience significant side effects. However, some men may experience nausea, facial flushing, hot flush, indigestion, blurred vision, visual disturbance, stuffy nose, and dizziness. Very rare side effects include allergic reactions, chest pains, fits, and prolonged painful erections, which require immediate medical attention.

Can I use Sidena with other erectile dysfunction treatments?

You should not use Sidena concurrently with other erectile dysfunction treatments unless directed by a healthcare provider. This includes both other oral medications and topical treatments. Using multiple treatments together can increase the risk of side effects and may not increase efficacy.

Can I take Sidena with other medications?

Some medications can interact with Sidena, notably nitrates used to treat angina and heart disease. Always disclose any medications you are currently taking to your healthcare provider before starting Sidena.

What is the difference between Viagra, Viagra Connect, and Sidena (generic sildenafil)?

Viagra, Viagra Connect, and Sidena (generic Viagra) are related medications used to treat erectile dysfunction (ED), but they have some differences:

Viagra: Viagra is a prescription medication, and is the branded version of sildenafil, developed by Pfizer. It was the first medication approved for the treatment of ED. Viagra contains the active ingredient sildenafil and is available in various dosage strengths, including 25mg, 50mg, and 100mg. A prescription is required to obtain Viagra.

Viagra Connect: Viagra Connect is an over-the-counter version of Viagra. It contains the same active ingredient, sildenafil citrate, in a 50mg dosage strength. Viagra Connect is designed for men over 18 years old and can be purchased without a prescription from pharmacies or authorized online retailers.

Sidena (generic sildenafil): Sidena is the generic version of Viagra. Like Viagra, it contains sildenafil citrate as the active ingredient and is available in various dosage strengths. Generic sildenafil is bioequivalent to Viagra, meaning it has the same effectiveness and safety profile. It is often available at a lower cost than the branded version and requires a prescription in most cases.
