12.2 Pharmacodynamics
Talk with your doctor about other drug options that may work for you. Sildenafil and tadalafil are alike because they both can treat ED and PAH. However, tadalafil has a few distinctions from sildenafil. Tadalafil is the generic name for the erectile dysfunction drug Cialis. There are two versions of the drug: a version that can be taken as needed Cialis 5-mg daily dosing is the only PDE5 inhibitor dose approved for treating an enlarged prostate; improving ED symptoms is an added benefit of the daily dose.
Interactions that increase your risk for side effects
Because of the “as needed” version of tadalafil, some users may find this option more convenient. The downside, however, is that side effects tend to last longer too. The main difference between generic sildenafil and Viagra is marketing. The main ingredient in Viagra is sildenafil, meaning that the drugs are essentially the same. However, Viagra is marketed and prescribed strictly for erectile dysfunction, while generic sildenafil can be prescribed for PAH as well. Dose may be increased based on symptoms and tolerability.
- Common side effects include headaches, flushing, and nasal congestion.
- Serious side effects are rare but may include vision changes or prolonged erections.
- Report any adverse reactions to a healthcare provider immediately.
Vasodilation effects may be more common in patients with hypotension or on antihypertensive therapy.
What happens if I miss a dose?
Viagra is also known as “the little blue pill” because of its blue color, while generic sildenafil tends to be a white color.
