Generally, Sildenafil, Levitra (vardenafil), and Cialis (tadalafil) share similar side effect profiles, although the frequency and severity can vary. Headaches are common with all three, affecting around 10-15% of users. Facial flushing (redness) is also prevalent, possibly slightly more so with tadalafil.
Gastrointestinal Effects
Upset stomach, nasal congestion, and dyspepsia (indigestion) occur with some frequency across these medications. Sildenafil may be associated with a slightly higher incidence of dyspepsia compared to vardenafil and tadalafil. However, these effects are usually mild and transient.
Visual Disturbances
Visual changes, such as altered color perception (blue tinge) or blurred vision, are more often reported with sildenafil, though they can occur with the others. These visual side effects are typically temporary. If persistent visual disturbances occur, seek immediate medical attention.
Muscle and Back Pain
Muscle aches and back pain are reported more frequently with tadalafil than with sildenafil or vardenafil. While not always severe, this discomfort warrants consideration if you have pre-existing back issues.
