If you're taking Tadaga 5 mg for the first time, expect the effects to begin within 30 to 60 minutes after ingestion. It enhances blood flow to help achieve and maintain an erection, but sexual stimulation is still required. The effects can last up to 36 hours, allowing for more natural timing of intimacy. Beginners may experience mild side effects such as headache, flushing, nasal congestion, or upset stomach. It's important not to mix it with alcohol, nitrates, or other erectile dysfunction medications. Always follow your doctor’s instructions and start with the lowest effective dose to monitor how your body responds.
