Epanutin 50mg Infatabs shortage in the UK

3 May 2019

Update May 3 2019: Pfizer now expects Epanutin Infatabs will be back in stock in November 2019.

Original story March 26 2019: Pfizer, the makers of Epanutin (phenytoin), have told us there will be a temporary shortage of Epanutin 50mg Infatabs. They expect it will be out of stock from 1 May for a few weeks. They do not know the exact date when it will be back in stock.

While Epanutin Infatabs are out of stock, Pfizer will be importing a Canadian version of chewable phenytoin tablets called Dilantin Infatabs. The active ingredient is the same, but there may be differences between Epanutin and Dilantin that for some people could affect seizure control and/or side-effects. If you need to change from one version of phenytoin to another this should be closely monitored by your doctor. This monitoring may involve doing blood tests to check that you have the right levels of phenytoin in your blood.

If you take Epanutin Infatabs we would advise you to talk to your GP or epilepsy specialist  as soon as possible. This is in case any changes need to be made to your treatment while the medicine is out of stock.

We will update this page as soon as we know more about this stock situation.
