How and When to Take Viagra Extra Dosage
Viagra Extra Dosage, typically available in 100 mg form, serves to address erectile dysfunction. Timing plays a crucial role in its efficacy. Consumption should occur approximately 30 to 60 minutes before sexual activity. A gap of at least 24 hours must exist between doses. Swallow the tablet whole with water. Avoid high-fat meals close to dosing time. Such meals delay absorption, impacting onset time.
Adherence to medical guidance ensures optimal results. Medical evaluation determines the correct dosage. Individual factors, including age and underlying health conditions, influence the prescribed amount.
For patients with renal or hepatic impairment, dosage adjustments might be necessary. These patients should exercise caution and seek specialist advice. Avoid alcohol consumption when taking Viagra Extra Dosage. Alcohol reduces blood flow, hindering performance.
Mechanism of Action
The active component, sildenafil, is a phosphodiesterase type 5 (PDE5) inhibitor. It enhances erectile response when a man is sexually stimulated. Sildenafil works by relaxing the blood vessels in the penis, allowing increased blood flow.
Its mechanism focuses on blocking PDE5 in the corpus cavernosum. This blockade maintains levels of cyclic guanosine monophosphate (cGMP). As cGMP levels remain elevated, smooth muscle relaxation and inflow of blood to the penile tissue occur. This biochemical process culminates in an erection.
Who Can and Cannot Take Viagra Extra Dosage
Viagra Extra Dosage is suitable for adult men with erectile dysfunction. Men with cardiovascular disorders must consult healthcare providers prior to use. The medication may exacerbate conditions like severe heart disease. Those on nitrates or nitric oxide donors should avoid sildenafil.
Women and children must not use this medication. Men with anatomical deformation of the penis should exercise caution. Those with conditions predisposing them to priapism should not use Viagra Extra Dosage.
Viagra Extra Dosage Interactions
Sildenafil interacts with numerous medications. Concomitant use with nitrates leads to hypotension. Antihypertensives, especially alpha-blockers, may require dosage adjustments. Combination with CYP3A4 inhibitors like ketoconazole increases plasma levels of sildenafil.
Ritonavir and other protease inhibitors significantly elevate sildenafil levels. Inform healthcare professionals about all medications and supplements being taken. Grapefruit juice can affect drug metabolism. Consumption alongside sildenafil is discouraged.
Side Effects
Common side effects include headache, facial flushing, and indigestion. Vision changes, such as color tinge, may occur. Nasal congestion and dizziness are noted occasionally. Seek immediate medical attention if an erection lasts more than four hours.
Rare but severe side effects include sudden vision or hearing loss. Cardiovascular events, although uncommon, have been reported. These include myocardial infarction and stroke. Patients experiencing chest pain or severe dizziness should stop use immediately.
