Increased Energy or Anxiety: Some people might experience increased energy or anxiety, which could interfere with sleep.
Side Effects: Common Fildena Chewable 100 mg side effects include headaches and flushing, which might disrupt sleep.
Timing of Dosage: Taking it close to bedtime might affect sleep quality or timing, as the drug's effects can last for several hours.
If you’re experiencing sleep disturbances and suspect they might be related to Fildena or any other medication, it's a good idea to discuss this with your healthcare provider. They can help determine if the medication might be affecting your sleep and offer advice on managing any side effects.
