Depending on the specific condition and its severity, your healthcare provider may need to adjust the dose of Tadarise 2.5 mg or monitor you more closely for potential side effects.

3. Potential interactions: Some medications used to treat immune system disorders, such as corticosteroids or immunosuppressants, may interact with tadalafil. It's essential to inform your healthcare provider about all medications you are taking, including prescription medications, over-the-counter drugs, and supplements, to avoid potential interactions.
