Generally, Cialis 20mg provides sufficient improvement for most men experiencing erectile dysfunction. Increasing the dose to 40mg may enhance the effect for some, but it also raises the likelihood of side effects. The choice depends on individual response and tolerance.
Efficacy
Both dosages successfully treat ED for many users. However, some men find a 40mg dose offers a longer duration of effect or improved hardness of erection. Clinical trials show a higher success rate with 40mg for some patient subgroups, though this isn’t universally true. Start with 20mg; only increase to 40mg if necessary and under medical supervision.
Side Effects
Higher doses correlate with a greater risk of side effects. Common side effects for both dosages include headache, flushing, nasal congestion, and indigestion. A 40mg dose increases the chance of experiencing these, and potentially more severe side effects like back pain or muscle aches. Always discuss potential side effects with your doctor before taking either dosage.
