Summary
Neostigmine increases acetylcholine at synapses while umeclidinium blocks muscarinic receptors, so their effects partly oppose each other. Muscarinic effects of neostigmine may be reduced, while the effect on nicotinic transmission is unaffected, and the clinical impact of inhaled umeclidinium is likely small.

Neostigmine and Umeclidinium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
