Side Effects of Priligy

Priligy, like all drugs, can cause side effects in susceptible people. If you notice any of the following four side effects, you should stop taking Priligy straight away and inform your doctor.

  1. Fits or seizures
  2. Feeling faint or light headed when standing up
  3. Mood changes
  4. Suicidal thoughts

Fainting when standing up

Priligy can cause your blood pressure to drop when you stand up, causing light headedness or actual fainting. In order to lessen the risk of this happening, you should always:

  • Swallow Priligy with a complete glass of water, not just a mouthfull.
  • Do not take Priligy if you are dehydrated. You may be dehydrated if you have been sweating a lot, have a high temperature, diarrhoea or vomiting, or have had nothing to drink for the previous 4-6 hours.
  • If when you stand up you feel faint or light headed, either lie down or sit with your head lowered between your knees - then if you do faint you will not fall and hurt yourself.
  • Stand up slowly if you have been lying down for a while to give your blood pressure chance to adjust.
  • Do not drive or operate machinery if you feel faint when taking Priligy.
