Caution is suggested in patients with brain disorder, former history of convulsions or patients with predisposing factors for brain disorder.
Concomitant use of N-methyl-D-aspartate (NMDA)- antagonists like amantadine, Ketalar or dextromethorphan ought to be avoided. These compounds act at identical receptor system as memantine, and thus adverse reactions (mainly central systema nervosum (CNS)-related) additionally be|is also} a lot of frequent or a lot of pronounced (see also section four.5).
Some factors which will raise piddle pH (see section five.2 'Elimination') might necessitate careful watching of the patient. These factors embrace forceful changes in diet, e.g. from a carnivore to a eater diet, or a colossal activity of alkalising internal organ buffers.

• There could also be a chance of reduced body fluid level of HydroDIURIL (HCT) once memantine is co-administered with HCT or any combination with HCT.
• In post-marketing expertise, isolated cases with international normalized quantitative relation (INR) will increase are reportable in patients concomitantly treated with anticoagulant medication. though no causative relationship has been established, shut watching of coagulation factor time or agency is advisable for patients concomitantly treated with oral anticoagulants.
