Fildena Professional contains sildenafil citrate, the same active ingredient as in regular Fildena or Viagra, and is used to treat erectile dysfunction (ED). It’s known for its fast-acting formulation, as it comes in a chewable tablet form, allowing for quicker absorption and a faster onset of action compared to standard tablets. While Fildena Professional is generally safe for most individuals, like all medications, it can interact with certain other drugs, leading to potentially harmful effects. Below are the key interactions to be aware of when taking Fildena Professional with other medications: 1. Nitrates (e.g., Nitroglycerin) Dangerous interaction: Taking Fildena Professional with nitrate medications (used to treat chest pain or angina) can cause a severe drop in blood pressure (hypotension). This can lead to symptoms like dizziness, fainting, or even heart attack in extreme cases. Fildena Professional Common nitrate medications include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Recommendation: If you're taking any nitrate medication, you should never take Fildena Professional or any sildenafil-based drug. 2. Alpha-Blockers (e.g., Doxazosin, Tamsulosin) Interaction with blood pressure: Alpha-blockers, used to treat high blood pressure or benign prostatic hyperplasia (BPH), also work by lowering blood pressure. When combined with sildenafil, they can cause an additive effect, leading to low blood pressure and symptoms like dizziness or fainting.
