If you're allergic to other erectile dysfunction (ED) medications, particularly those containing sildenafil or similar active ingredients like tadalafil, vardenafil, or avanafil, you should exercise caution before using Malegra Professional. Malegra Professional contains sildenafil, the same active ingredient found in Viagra and Aurogra. If you've had allergic reactions to sildenafil or similar medications, it is not advisable to use Malegra Professional.

Allergic reactions to ED medications can include symptoms like swelling, rash, itching, breathing difficulties, and severe dizziness. If you're unsure about the allergy or have experienced any adverse reactions in the past, it's best to consult with your healthcare provider. They can help you explore alternative treatments for erectile dysfunction that may be safer for you.
