What side effects can this medication cause?
Like most medications, there are precautions you should take before using this drug. Make sure you talk with your doctor about: any other drugs, medications, herbs, or supplements you take or plan to take any medical conditions or surgeries you have or plan to have if you are pregnant or plan to become pregnant There are other drugs available to treat your condition. Some may be better suited for you than others. 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.
Antihypertensive and α-Adrenergic Blocking Agents
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. 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. Cardiovascular: Cardiac status/risk factors (prior to initiation); blood pressure (periodically during treatment in patients with PAH on concomitant anti-hypertensive agents) Drug Interactions: For concomitant use of medications that may be contraindicated or for dose adjustment (at baseline and during treatment) Ocular: NAION risk factors (prior to initiation) Read the US FDA-approved patient labeling (Patient Information and/or Instructions for Use).

However, Viagra is marketed and prescribed strictly for erectile dysfunction, while generic sildenafil can be prescribed for PAH as well. Viagra is also known as “the little blue pill” because of its blue color, while generic sildenafil tends to be a white color.

Known hypersensitivity to either the active component or to any of the ingredients of the tablet, injection, or oral suspension; hypersensitivity reactions have been reported, including anaphylactic reaction, anaphylactic shock, and anaphylactoid reaction Safety and efficacy have not been established in patients with ED younger than 18 years.
