Duratia 90mg is more likely to prolong your time of ejaculation significantly. However, it depends on the severity of PE you have as well as how your body reacts to the drug. You should only use this medicine when you want to make love, but not more than once in 24 hours. Some men may experience side effects such as nausea, dizziness, or sweating. Please note that taking more than one dose will not make you last longer.
