Is it safe to treat swelling in feet and legs with Lasix while taking Lithium?
Lasix can cause dehydration which raises your lithium blood level and could potentially cause lithium toxicity ~ which is truly nasty.. They should be used together only under a doctor's strict supervision and he may call for periodic blood tests to monitor your lithium level.
If two different doctors are prescribing your medications be sure they both know ALL the medications you are taking.

medianswers; Yes but alot depends also on the dose of both this is why as wildcat; has said if they did or did not come from the same doctor you always tell them what else or ask them about this problem and also it another good reason to fill your prescriptions all at the same pharmacy so as the pharmacist can see any interactions between your medications. If this was a different doctor call them and or call the doctor prescribing the lithium and tell the doctor what you are now taking and when should you have a blood test.
