The shelf life of Tadacip 20 mg tablets, which contain Tadalafil (used to treat erectile dysfunction and symptoms of benign prostatic hyperplasia), is typically around 2 to 3 years from the manufacturing date, depending on the specific brand and storage conditions. However, the shelf life can vary based on several factors: 1. Expiration Date: Always check the expiration date printed on the packaging or blister pack. This date indicates the period during which the manufacturer guarantees the full effectiveness and safety of the medication. 2. Storage Conditions: Tadacip 20 mg tablets should be stored in a cool, dry place at room temperature (usually between 20°C to 25°C or 68°F to 77°F). It is important to keep the tablets in their original packaging, away from moisture, heat, and direct sunlight, as these conditions can degrade the medication more quickly. 3. Signs of Degradation: If the medication is past its expiration date or if it has been stored improperly, the effectiveness of Tadacip 20 mg may be reduced. Tablets that are discolored, cracked, or have an unusual odor should not be used and should be properly disposed of.
