An aluminium/magnesium hydroxide antacid reduced the AUC of mycophenolate
by about 20% in one study, but the clinical
relevance of this is uncertain.
The US manufacturer says that aluminium/magnesium antacids
can be used in patients taking mycophenolate, but that they should not be given simultaneously. With many other antacid interactions, a 2 to 3 hour separation is usually sufficient to avoid an interaction.
