Fildena 150 mg should be taken at least one hour before sexual activity. It should not be taken with alcohol or high-fat meals, as these can reduce the drug's effect. It also should not be taken if you are pregnant or breastfeeding. The combination of alcohol and medication can lead to severe complications. The drug may cause serious headaches, blurred vision, and extreme dizziness. Side effects are rare, but they can happen if you are not taking the right dose or if you take too much.
