Avana 100 mg (avanafil) can interact with several other medicines, mainly because it lowers blood pressure and acts on the same PDE?5 pathway as other erectile?dysfunction (ED) drugs. The most important interacting groups include:
Nitrates (e.g., nitroglycerin, isosorbide dinitrate/mononitrate) used for chest pain: Combining Avana 100 mg with nitrates can cause a sudden, dangerous drop in blood pressure, leading to fainting, stroke?like symptoms, or heart?related emergencies. These must never be used together.
Other PDE?5 inhibitors (such as sildenafil/Viagra, tadalafil/Cialis, vardenafil/Levitra) or other ED?augmentation drugs: Using more than one PDE?5 inhibitor at the same time increases the risk of low blood pressure, priapism, and cardiovascular stress.
Alpha?blockers (e.g., tamsulosin, alfuzosin, doxazosin) used for blood pressure or prostate problems: These can already lower blood pressure, and adding AVANA 100 MG may cause dizziness, lightheadedness, or fainting, especially if therapy is not stabilized first.
Certain antifungals and antibiotics (strong CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, clarithromycin): These can raise avanafil levels in the blood, increasing the chance and severity of side effects.
Alcohol and grapefruit products can also worsen low?blood?pressure effects or dizziness, so many sources advise limiting or avoiding them around the time of Avana 100 mg. Always tell your doctor about all your medicines, including over?the?counter products and supplements, before starting Avana 100 mg.
