Some people with mast cell diseases are prescribed a medication called ketotifen, which is an H1 antihistamine and mast cell stabiliser. It can sometimes be a challenge to obtain. On this page we try to keep patients, pharmacists and doctors up to date with the latest information on how to obtain ketotifen.
Update as of August 8, 2019
Ketotifen Tablets are currently UNavailable. Though there may still be stock left from earlier supplies, no new tablets are being imported at this time. It is worth ringing a range of pharmacies (chains and independent) to see if you can find supplies now, but at some stage that supply will be depleted. We do not have an update at this time as to how long the tablets will be unavailable.
The supplier has suggested that patients discuss with their doctors whether trying the liquid (details below) is a good alternative. Please discuss with the prescribing doctor how to try the new formulation. We advise anyone making such a substitution to do so with slowly and cautiously since people with mast cell diseases can react to the inactive ingredients in medications.
This problem has been reported to the UK authorities.
