How to use Priligy
The usual dose of Priligy is 30mg. Your doctor may increase the dose to 60mg if required after trying the 30mg strength. You should take the medicine between one and three hours before sexual activity. Swallow the tablet whole to avoid a bitter taste, with at least one full glass of water. This may help reduce the risk of fainting (see the side effects section).
Priligy can be taken with or without food, but it is not advised you drink alcohol with the treatment as it may increase its effects such as feeling dizzy, sleepy and experiencing slowed reactions. Also, the risk of fainting with Priligy is increased if taken with alcohol.
Do not take Priligy more than once every 24 hours.
Caution is required when taking Priligy at the same time as Viagra (sildenafil), Levitra (vardenafil) or Cialis (tadalafil) - you’ll find further information on this below.
What are the side effects of Priligy?
Priligy is similar to many other medicines in that it can cause side effects - but many people will not get them.
Stop taking Priligy and see your doctor straight away if:
- You have fits (seizures)
- You faint or feel light-headed when you stand up
- You notice any changes in your mood
- You experience any thoughts of suicide or self-harming
Fainting and low blood pressure
Priligy can make you faint or make your blood pressure drop when you stand up. To help lower the chance of this happening:
- Take Priligy with at least one full glass of water
- Do not take Priligy if you are, or are feeling dehydrated This can happen if you have not had anything to drink in the past four to six hours, you have been sweating for a long time, or you have an illness with symptoms including a high temperature, diarrhoea or vomiting.
If you feel like you might faint (symptoms include feeling sick, feeling dizzy, light-headed, confused, sweaty or an abnormal heartbeat), or feel light-headed when you stand up, immediately lie down so your head is lower than the rest of your body or sit down with your head between your knees until you feel better. This will stop you from falling and hurting yourself if you do faint. Do not stand up quickly after you have been sitting or lying down for a long time. Do not drive or use any tools or machines if you feel faint when taking this medicine.
Tell your doctor if you faint when taking this medicine.

Other important information you’ll need
Priligy must only be used with caution if it is to be taken at the same time as medicines for impotence, such as Viagra, Levitra or Cialis. It is possible that when taken at the same time, the combination of medicines can lower your blood pressure and make you feel faint when you are standing up. To avoid this potential side effect, leave at least 24 hours between taking Priligy and taking Viagra or Levitra; and if taking Priligy and Cialis leave at least 48 hours If you intend to take Priligy with any of these drugs, it is important that you tell the doctor, and also ensure that for the first few times you take the medicines together, you do so in a safe environment. Ensure that you are in a position to be able to sit or lie down if you do feel faint after taking the medicines in combination.
