Men with asthma or allergies should approach Cenforce 100 with caution. While the medication itself doesn’t typically worsen asthma, some of its side effects—such as nasal congestion, shortness of breath, or dizziness—can mimic or trigger respiratory discomfort. Additionally, individuals with severe allergies should check for potential allergic reactions to sildenafil or inactive ingredients in the pill. Always consult a healthcare provider before use to ensure it won’t interfere with asthma medications or provoke an allergic response. Monitoring your body’s reaction after the first dose is crucial for safe and effective use.
