6.2 Postmarketing Experience
Co-administration is possible, but only after the α-blocker dose is stabilized; otherwise, symptomatic hypotension may occur. If I am already on tamsulosin, how long should I wait before taking vardenafil? Clinical studies suggest dosing vardenafil at least two hours after tamsulosin minimizes additive blood-pressure effects. Yes; grapefruit compounds inhibit CYP3A4 and can unpredictably raise drug levels, increasing side-effect risk. Even one glass may alter metabolism; consistent, limited intake or complete avoidance is advisable to maintain predictable exposure.

Are over-the-counter sexual enhancers safe with vardenafil? Many contain undeclared PDE5 analogues or nitrates, posing serious interaction risks; avoid concurrent use. What if I experience dizziness after dosing? Sit or lie down until symptoms pass; if severe or persistent, seek medical attention as this may indicate significant hypotension. No evidence supports physical dependence, but psychological reliance on performance medications can develop, warranting periodic assessment. Moderate hepatic dysfunction (Child-Pugh B): 5 mg orally once a day, as needed, approximately 60 minutes before sexual activity. The maximum dose should not exceed 10 mg. Severe hepatic dysfunction (Child-Pugh C): Use should be avoided.

Product Overview
We used genuine 20-mg Levitra tablets that were sold in Japan and tablets from Bayer AG (Germany) as controls. In April 2015, we obtained 28 samples from 15 websites on the internet. Our authenticity investigations revealed that 11 (40%) were genuine products and 17 (60%) were falsified products. Handheld NIR and Raman results revealed that the falsified products had different spectra to the genuine products. Principal component analysis of the NIR and Raman spectra showed variation among the falsified products.

The 11 genuine products were of good quality, and the 17 falsified products were of poor quality.
