Help please! Is citalopram and dental treatment safe together?

Yes. If the. Medication is taken appropriately as prescribed by your physician, there is no problem. Always best to let your dentist know what meds you are on as part of your medical history review. Hope this helps.
No Contraindication. There is no known contraindications between the drug citalopram (celexa) and lidocaine, the active vasoconstrictor in most local anesthesia. That said, make sure your dmd knows every medicine you take, so there are no issues, potential issues with any other drugs, or drug combinations.
