How long do Priligy side effects last
Priligy side effects are different for everyone, but most common side effects should go away quickly. If you get mild side effects, wait until you have used Priligy a few times, as these may go away. If they do not and you are still getting side effects after a few weeks of treatment, speak with your doctor. If any side effects last longer than 24 hours contact your doctor.
What to do if you get Priligy side effects
An uncommon side effect of Priligy is fainting and low blood pressure. Before you take Priligy, your doctor may check your blood pressure from lying down to standing up or ask about any history of faints or dizziness. To lower the chance of fainting, make sure to:
- not take Priligy if you are dehydrated, this can happen if you have been sweating a lot, have not drank anything in over 4 hours, or have diarrhoea or vomiting (being sick)
- take your dose with at least one full glass of water
- not stand up quickly if you have been sat or lying down for a long time
- not drive or use heavy machinery if you feel faint
If you do feel faint or light headed, make sure to lie down so that your head is lower than the rest of your body, or sit down and put your head between your knees until you stop feeling faint. This can stop you hurting yourself if you faint. Speak to your doctor if Priligy makes you faint or feel faint.
For other side effects such as headache, make sure to drink plenty of water and take paracetamol. Do not take ibuprofen with Priligy, unless you have spoken to your doctor first. If you feel sick, try to take Priligy with food.
If you have other side effects that bother you, speak to your doctor.
