Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Inosine and Levetiracetam in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Inosine and Levetiracetam

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Levetiracetam and Inosine in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Inosine safety at a glance

Inosine overall Use caution Inosine raises uric acid, which may be a problem for people with gout or kidney issues.
Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Levetiracetam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Levetiracetam is filed under 3 classifications — anticonvulsants, cns depressants, oral drugs. Inosine has documented interactions with 1 drug class — the most serious being antigout drugs (moderate) — and none of Levetiracetam’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

Inosine Does Interact With Other Medications

Inosine has 9 moderate known drug interactions in our database — Levetiracetam isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

What Inosine Itself Has Been Linked To

This is not an interaction — nothing below involves Levetiracetam. It is the side-effect record for Inosine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Inosine, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Kidney stones Worth acting on Additional detail

    “Orally, inosine has been reported to cause uric acid crystals and symptomatic uric acid kidney stones. Uric acid kidney stones occurred more frequently when inosine was taken concurrently with calcium supplements.”

Everything above comes from the Natural Medicines adverse-effect record for Inosine — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Levetiracetam’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Levetiracetam column appears here.

From our pharmacist’s overview on the Levetiracetam page

“I would read this page carefully rather than casually. Levetiracetam (Keppra, Spritam) controls seizures, and both hazards on this list run through that fact.”

About Inosine

What is Inosine?

  • Athletic performance and energy
  • Multiple sclerosis (raising uric acid)
  • Parkinson's disease (raising uric acid)
  • General health and recovery

Inosine is a nucleoside (a building block of DNA and RNA) that the body makes on its own and is also sold as a supplement, mostly marketed for athletic performance. Solid evidence that it boosts exercise performance is lacking, and because it raises uric acid levels, it may pose risks for people with gout or kidney problems. Talk with your pharmacist or doctor before using it.

Not applicable; inosine is a naturally occurring compound (a nucleoside), not a plant part · Capsules, tablets, powder

An interaction check asks whether these two react with each other — it does not ask whether Inosine is a good idea for someone in your situation. Here is what our Inosine record says about it on its own.

Inosine: dosing

There is no well-established, standardized dose of inosine. Amounts used in studies have varied, and there is no proven safe or effective dose for general use.If you choose to use an inosine product, follow the directions on the label and do not exceed the recommended amount. Do not assume that taking more will give better results.

About Levetiracetam

What Is Levetiracetam Used For?

Brand names: Keppra, Elepsia XR, Spritam

Levetiracetam is used to treat several types of seizures. It treats partial-onset seizures (seizures that start in one area of the brain) and is used as add-on therapy for myoclonic seizures (sudden, brief muscle jerks) in people with juvenile myoclonic epilepsy aged 12 and older, and for primary generalized tonic-clonic seizures (grand mal seizures) in people with idiopathic generalized epilepsy aged 6 and older.

Age eligibility varies by product. Keppra oral and Roweepra tablets treat partial-onset seizures in patients as young as 1 month. Spritam and levetiracetam tablets for oral suspension treat partial-onset seizures in patients 4 years and older weighing more than 20 kg. Extended-release products — including Elepsia XR, Keppra XR, and Levetiracetam ER — are approved only for partial-onset seizures in patients 12 years and older. Injectable forms are used intravenously when a patient temporarily cannot take oral medication.

Most-Reported Side Effects for Levetiracetam
