Some people are allergic to Kamagra because it contains sildenafil citrate as its active ingredient, along with various inactive excipients such as fillers, dyes, or preservatives. An allergy can occur when the immune system mistakenly identifies one of these substances as harmful, triggering symptoms like rash, itching, swelling, dizziness, or difficulty breathing. Individuals with a history of allergies to other medications, foods, or chemical compounds may be more susceptible. Additionally, reactions can vary in severity from mild skin irritation to potentially life-threatening anaphylaxis. Before taking Kamagra, it is important to review the ingredient list and consult a healthcare professional if there is a history of allergies. People with sildenafil sensitivity should avoid Kamagra entirely.
