Combination products containing edrophonium chloride
A combination is a different drug — different dosing, different warnings. It is listed here so you can find it, not so you can substitute it.
What people report to the FDA about edrophonium chloride
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 10 reports naming edrophonium chloride, and the FDA flagged 70% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- agitation2 reports
- bradycardia2 reports
- bronchospasm2 reports
- crepitations2 reports
- miosis2 reports
- ophthalmoplegia2 reports
- pulmonary oedema2 reports
- salivary hypersecretion2 reports
Read these as a signal, not a rate. A report does not mean edrophonium chloride caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
Can you take edrophonium chloride with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run edrophonium chloride against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.

We track 2 edrophonium chloride-containing products in the U.S.: Tensilon and Tensilon Preservative Free. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
