Both Stendra (avanafil) and Levitra (vardenafil) share similar side effects, but their frequency and severity can differ. Common side effects for both include headache, flushing, nasal congestion, and back pain. However, Stendra users report slightly fewer instances of these compared to Levitra.
More serious, though rare, side effects include vision changes (blurred vision, sudden vision loss), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience any of these.
Regarding drug interactions, both medications can interact negatively with nitrates (used to treat angina) due to a risk of dangerously low blood pressure. Consult your doctor about all medications you are currently taking, including over-the-counter drugs and supplements, before starting either Stendra or Levitra. Grapefruit juice can also interact with Levitra, potentially increasing its effects. Stendra interactions are less extensively studied in comparison, but caution is still advised regarding simultaneous use with other medications.
Individual responses vary. Your doctor can help determine which medication is better suited for your specific needs and health profile, considering potential side effects and interactions based on your medical history.
