Yes, Mycin (antibiotic eye drops) and HA2 (Homatropine eye drops) are safe for someone with nephrotic syndrome. Since these are eye drops, they act locally with negligible absorption into the bloodstream, meaning they will not affect or harm the kidneys. HA2 is prescribed for two days instead of a single dose because a single drop only provides temporary relief for a few minutes. Continuous lubrication over 48 hours is necessary to keep the eye surface consistently hydrated, protect the cornea, and allow any irritation or minor scratches to fully heal.
