Combining Cialis and Viagra is strongly discouraged. This practice, often called the “Superman” combination, carries significant health risks and offers no proven benefit beyond what each drug provides individually. The potential side effects are amplified, significantly increasing the chance of experiencing dangerous consequences.
Both Cialis and Viagra are potent vasodilators, meaning they widen blood vessels. Taking them together dramatically increases this effect, potentially leading to dangerously low blood pressure, heart problems, including irregular heartbeat (arrhythmia), and even stroke.
The following table summarizes the potential dangers:
| Headache | Common | Significantly Increased |
| Muscle aches | Common | Significantly Increased |
| Low blood pressure | Possible | Highly Increased |
| Heart problems (arrhythmia) | Possible | Highly Increased |
| Stroke | Rare | Increased |
Always consult your doctor before taking any medication, especially when considering combining drugs. Your physician can assess your individual health status and provide tailored advice regarding treatment options.
Remember, there are safer and more effective ways to address erectile dysfunction. Your doctor can help you find the right approach for you. Never self-medicate.
