What's the same
Voltaren and Klonopin are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Voltaren belongs to Pain Relief Medications while Klonopin belongs to Anti-anxiety Medications. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Voltaren: Diclofenac reversibly inhibits cyclooxygenase enzymes COX-1 and COX-2, with somewhat greater selectivity for COX-2 than ibuprofen and naproxen. Klonopin: Clonazepam binds to the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance, hyperpolarising central nervous system neurons.
When Voltaren is preferred
Voltaren is approved in adults for the treatment of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute musculoskeletal pain, post-surgical pain, primary dysmenorrhoea, acute migraine and ureteric colic.
When Klonopin is preferred
Klonopin is approved in adults for the treatment of certain seizure types, including absence and atypical absence seizures, myoclonic and akinetic seizures, and as adjunctive therapy in Lennox-Gastaut syndrome.
Frequently asked questions
Is Voltaren or Klonopin better? ▾

Can I switch from Voltaren to Klonopin? ▾
Switching between Voltaren and Klonopin is rarely an appropriate decision since they belong to different classes and treat different conditions. The real question is usually whether the diagnosis calls for one medication or the other — which the prescriber resolves.
Do Voltaren and Klonopin have the same side effects? ▾
No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
