I’m Dr Sébastien Beley, a Paris-based urological surgeon and andrologist specializing in male sexual health. Today, I’d like to address a question frequently asked by my patients: is it safe to combine Viagra(sildenafil) with Cialis(tadalafil)? This question is particularly relevant for those who suffer from erectile dysfunction and wish to optimize their treatment. In this article, I’ll explain in detail how these two drugs work, when they can be combined, the precautions to be taken, and the potential side effects.

Introduction to erectile dysfunction treatments: Cialis and Viagra

Erectile dysfunction, or erectile dysfunction, is a common problem affecting a large number of men worldwide. It can be linked to a variety of factors, including chronic diseases such as diabetes, lifestyle habits such as smoking, and psychological causes. Phosphodiesterase type 5 inhibitors (IPDE5) are the first line of treatment.

Cialis, whose active ingredient is tadalafil, is often prescribed as a 5 mg daily dose. This treatment offers a long-lasting, stable effect, enabling better vascularization of the cavernous bodies of the penis, making it easier to achieve and maintain an erection over time.

Viagra, whose active ingredient is sildenafil, is generally taken on demand, around one to two hours before intercourse. It ideally requires an empty stomach for optimal efficacy, and acts more rapidly but for a shorter duration than tadalafil.

Why consider combining Viagra and Cialis?

In some cases, daily treatment with Cialis 5 mg may not be sufficient, particularly when the underlying cause of erectile dysfunction is not fully controlled. For example, in poorly-balanced diabetic patients or those who continue to smoke despite their erectile dysfunction, tadalafil alone may not ensure satisfactory erection quality.

In these situations, the addition of a second medication, taken only at the time of sexual intercourse, may be considered. Sildenafil, in the form of Viagra or its generic equivalents, then becomes an interesting complement.

Presentation of oral and sublingual forms of sildenafil

Sildenafil is best known as a tablet to be swallowed, but it is also available in orodispersible film form (to be dissolved on or under the tongue). These preparations, marketed under various brand names such as Viagra, Zibilin or Visarsin, enable faster absorption and direct distribution into the bloodstream, which can improve treatment responsiveness.

Can Viagra and Cialis be taken at the same time?

The key question is: is it safe to combine these two treatments? Officially, drug inserts advise against this combination. However, clinical experience accumulated over more than 25 years with these molecules shows that this combination is possible under certain conditions.

Combining daily Cialis 5 mg with an occasional Viagra tablet can offer several advantages:

• Long-term stability: tadalafil ensures constant vascularization of the corpora cavernosa, improving the overall quality of erections.
• Fast, one-off effect: when taken before intercourse, sildenafil boosts erectile response thanks to its more immediate action.
• Treatment optimization: this two-pronged approach can sometimes restore efficacy comparable to that observed in early trials with tadalafil alone.

How do you combine these treatments?

Typically, the patient continues to take Cialis 5 mg every day, and adds a tablet of Viagra (or its equivalent) only before sexual intercourse. The aim of this method is not to double the dose of IPDE5, but to take advantage of the complementary properties of the two molecules.

What are the risks and side effects of the combination?

As with any drug combination, potential risks must be assessed. The most frequent side effects of this combination are :

• Decreased blood pressure, which may lead to a feeling of fatigue or weakness.
• Facial redness and sensation of heat in the skin, linked to drug-induced vasodilation.

These effects, although unpleasant, are generally not serious. However, in certain patients, particularly those with a history of serious cardiovascular disorders such as stroke or poorly controlled hypertension, this combination may present an increased risk. This is why it is imperative to consult your doctor before considering this strategy.

Precautions to be taken

Before combining Viagra and Cialis, it is important to :

1. Talk to your GP or urologist to assess your overall health.
2. Avoid this combination if you have a severe cardiac history, including stroke or uncontrolled hypotension.
3. Never increase the dose of either without medical advice.
4. Tell your doctor about all the medications you are taking, as some may interact with IPDE5s.

The doctor’s role in the personalized management of erectile dysfunction

Erectile dysfunction is a multifactorial pathology that requires individualized management. The choice of treatment, whether Cialis, Viagra or a combination of the two, must be based on a comprehensive assessment that includes :

• A thorough medical check-up to identify underlying causes (diabetes, hypertension, cardiovascular disorders, etc.).
• An analysis of lifestyle habits and risk factors (smoking, diet, physical activity).
• A discussion of the patient’s expectations and preferences regarding treatment.

As a specialist, I always recommend that my patients strictly follow medical advice and not hesitate to ask any questions they may have about the proposed treatments. The combination of Viagra and Cialis is not a universal solution, but it can be effective in certain specific cases.

Other alternatives and tips to improve erectile function

Beyond medication, it is important to take a holistic approach to improving sexual health:

• Smoking cessation: smoking is a major factor in vascular disorders and erectile dysfunction.
• Managing diabetes and other chronic diseases: good glycemic control is essential for preserving erectile function.
• Regular physical activity: sport improves blood circulation and cardiovascular health.
• Balanced diet: a healthy diet contributes to overall health and the quality of erections.
• Psychological follow-up: in the event of a psychological component, appropriate treatment may be required.

Conclusion: a possible but supervised association

The combination of Viagra and Cialis is a possible therapeutic option for certain patients suffering from erectile dysfunction, particularly when tadalafil treatment alone is not sufficient to guarantee a satisfactory erection. Although not officially recommended in package inserts, this combination has been used for over 25 years with an acceptable safety profile, subject to strict medical supervision.

It is essential to consult a healthcare professional before starting this combination, in order to assess the risks specific to each individual and ensure appropriate follow-up. With proper management, this dual strategy can restore confidence and significantly improve the quality of sexual life.

To deepen your understanding of erectile dysfunction and the treatments available, don’t hesitate to follow the advice of urology and andrology specialists on a regular basis. Sexual health is a fundamental pillar of general well-being, and there are many effective, personalized solutions available today.
