Tadact 20 mg and Revatio are not interchangeable medications, although they contain similar active ingredients. Here are some important differences between the two:

Active Ingredient: Tadact 20 mg contains Tadalafil as its active ingredient, while Revatio contains Sildenafil citrate.

Indications: Tadact 20 mg is primarily used to treat erectile dysfunction (ED) in men, whereas Revatio is indicated for the treatment of pulmonary arterial hypertension (PAH) in both men and women.

Dosage: The recommended dosage of Tadact 20 mg for ED typically ranges from 10 mg to 20 mg taken orally as needed, approximately 30 minutes before sexual activity. The dosage may be adjusted based on individual response and tolerability. On the other hand, the recommended dosage of Revatio for PAH is typically 20 mg taken three times a day, with or without food, approximately 4 to 6 hours apart.

Onset of Action: Tadact 20 mg typically has a faster onset of action compared to Revatio. The effects of Tadalafil can be observed within 30 minutes to 1 hour after ingestion and can last for up to 36 hours. In contrast, Revatio may take longer to produce noticeable effects, and its duration of action is shorter.

Safety Considerations: While both medications are generally safe when used as prescribed, they may have different side effect profiles and contraindications. It's essential to consult a healthcare provider before using either medication to ensure that it is safe and appropriate for your individual needs and health status.

Overall, Tadact 20 mg and Revatio are intended for different purposes and are not interchangeable. It's essential to use each medication only as prescribed by a healthcare provider and to follow their guidance regarding dosage, usage, and safety considerations.
