Get Adcirca Online

Adcirca is a brand-name prescription tablet containing tadalafil 20 mg. It is approved by the FDA to treat pulmonary arterial hypertension (PAH, WHO Group I) in adults. The standard prescribed dose is two 20 mg tablets taken together once daily (40 mg total), and its goal is to improve exercise capacity.

Adcirca is a phosphodiesterase type 5 (PDE5) inhibitor. By blocking PDE5, it increases levels of cyclic GMP in pulmonary vascular smooth muscle cells, causing those blood vessels to relax and widen. This reduces the resistance blood faces when moving through the lungs and lowers the workload on the right side of the heart.

Adcirca is sometimes used in combination with other PAH therapies, but drug interactions must be carefully evaluated. It must never be combined with nitrates or nitric oxide donors because the combination can cause a dangerous drop in blood pressure. Your Doctronic physician will review your full medication list before prescribing.

The most commonly reported side effects include headache, flushing, nausea, myalgia (muscle aches), nasopharyngitis, and back pain. These are generally related to the vasodilatory effect of the drug. If you experience sudden vision or hearing changes, chest pain, or a prolonged erection, seek immediate medical attention.

Yes. Adcirca is contraindicated in patients who use any form of nitrate medication (including nitroglycerin), guanylate cyclase stimulators such as riociguat, or who have severe hepatic impairment. Caution is also required in patients with hypotension, significant left ventricular outflow obstruction, or a recent history of stroke or heart attack. Your physician will screen for all of these.

Clinical studies showed measurable improvements in six-minute walk distance after 16 weeks of treatment. Some patients notice changes in breathing comfort and exercise tolerance earlier, but the full benefit typically develops over weeks of consistent daily use. It is important not to stop taking Adcirca without consulting your physician, as discontinuation can worsen PAH.
