Storing and using Tadalafil correctly is essential for its effectiveness and safety. I learned that it should be stored in a cool, dry place, away from direct sunlight and moisture. When it comes to usage, always follow the prescribed dosage and avoid mixing it with other medications, especially nitrates. It's important to communicate with your doctor about any health concerns or side effects you may experience. Lastly, never share your Tadalafil prescription with others, as it is tailored to your specific needs and health conditions.
