Learn More about Revatio

Common Brand Name

Revatio, known by its generic name sildenafil citrate, primarily treats pulmonary arterial hypertension (PAH). The same active component is marketed as Viagra for erectile dysfunction. This compound is a phosphodiesterase type 5 (PDE5) inhibitor. It facilitates smooth muscle relaxation and vasodilation, enhancing blood flow. Revatio is prescribed in specific dosages, like sildenafil 20 mg, optimized for PAH management. Unlike Viagra, it is not intended for erectile dysfunction at this dosage.

Pharmaceutical companies produce Revatio in tablet, oral suspension, and injectable forms. It’s essential to differentiate between Revatio and Viagra due to their distinct uses and recommended dosages. Physicians prescribe Revatio after careful patient evaluation. Brand recognition and trust are critical, as both Revatio and Viagra are manufactured by Pfizer, known for stringent quality control.

Correct Use

For effective Revatio treatment, adhere to the prescribed dosage. Typically, physicians recommend sildenafil 20 mg, taken three times daily, without regard to meals. Consistent dosing at approximately 4-6 hour intervals maximizes therapeutic outcomes. Patients must follow the healthcare provider’s instructions to ensure optimal efficacy.

Administering Revatio as an oral suspension requires proper shaking of the bottle for at least 10 seconds. Accurate dosing with the provided syringe is crucial. Injection is an alternative for individuals unable to swallow tablets or oral suspension. Precise administration by trained professionals minimizes risks.

Misuse or deviation from prescribed instructions can result in suboptimal treatment. Regular follow-up appointments enable healthcare providers to monitor patient progress and adjust the regimen if necessary. Consistent patient-provider communication is vital.

Revatio Precautions

Before initiating sildenafil 20 mg treatment, patients must disclose their medical history to the prescribing physician. Conditions like severe heart or liver problems, recent stroke or myocardial infarction, and hereditary degenerative retinal disorders contraindicate Revatio use.

Hypotension, severe dehydration, and certain rare inherited eye diseases warrant caution. The physician evaluates risks versus benefits to make informed prescribing decisions. Proper patient education regarding potential side effects, such as dizziness and visual disturbances, is imperative.

Patients should refrain from using Revatio alongside nitrate medications, often prescribed for angina. The combination can lead to a dangerous drop in blood pressure. Physicians must review current medications to avoid potential interactions, ensuring patient safety.

Revatio Interactions

Revatio interacts with various medications. Concomitant use with nitrates, such as nitroglycerin, is contraindicated due to significant hypotension risk. Alpha-blockers for hypertension or prostate issues can also potentiate blood pressure lowering effects.

CYP3A4 inhibitors, including ketoconazole and ritonavir, may increase sildenafil levels in the bloodstream, enhancing potential adverse effects. Conversely, CYP3A4 inducers, like rifampin, can reduce efficacy by lowering drug concentrations.

Informing healthcare providers about all current medications, supplements, and herbal products is essential. Comprehensive medical records allow for appropriate prescribing decisions and minimization of adverse interactions. This proactive approach mitigates potential complications.

Revatio Signs and Symptoms of Overdose

Overdose of sildenafil 20 mg presents identifiable symptoms, requiring immediate medical attention. Manifestations include severe dizziness, fainting, or persistent erection (priapism). Abnormal vision changes, including blurred vision or temporary loss, may occur.

Severe hypotension, characterized by acute dizziness, may compromise cerebral perfusion, leading to syncope. Recognizing these warning signs is critical for preventing further complications. Prompt response and seeking medical care prevent escalation.

Emergency intervention often involves supportive measures and symptomatic treatment. Monitoring vital signs and providing hydration address acute hypotension. Hospitalization may be necessary for severe cases to stabilize the patient. Recognizing overdose symptoms early can prevent adverse outcomes.

Is Non-Prescription Revatio Available?

Revatio is available by prescription only. It ensures proper medical oversight and individualized treatment plans. Unauthorized sources selling non-prescription versions pose significant risks. Counterfeit medications may contain inappropriate active ingredients, leading to ineffective treatment or harm.

Purchasing sildenafil 20 mg from unverified sources jeopardizes patient safety. Regulatory agencies, like the FDA, emphasize obtaining medications through licensed pharmacies. Adhering to this guidance safeguards against counterfeit or substandard drugs.

Prescription Revatio ensures quality control and authenticity. Healthcare providers tailor treatment plans to individual patient needs, enhancing therapeutic outcomes. Trusting legitimate medical channels guarantees safe and effective Revatio therapy. Avoiding non-prescription sources is imperative for maintaining health.
