What Is Ultram XR? Uses, Dosage, and What You Need to Know in 2026

If your doctor has prescribed Ultram XR — or if you've been searching for information about tramadol extended-release — this guide answers all the basic questions: what it is, what conditions it treats, how it's taken, what makes it different from other pain medications, and what the rules are around getting it filled.

What Is Ultram XR?

Ultram XR is a brand name for tramadol hydrochloride extended-release tablets. "Extended-release" (also abbreviated as ER or XR) means the medication dissolves slowly over time, providing continuous pain relief throughout the day from a single daily dose. This is in contrast to tramadol immediate-release (IR), which is taken every 4–6 hours.

The Ultram and Ultram ER brand names have been discontinued in the United States, but generic tramadol extended-release tablets remain available. You may also see it sold under the brand name ConZip.

What Is Tramadol ER Used For?

Tramadol extended-release is FDA-approved for the management of moderate to moderately severe chronic pain in adults when around-the-clock treatment is needed. It is not intended for as-needed pain relief. Common conditions for which it is prescribed include:

Chronic lower back pain

Osteoarthritis pain (knee, hip, spine)

Diabetic peripheral neuropathy (off-label)

Fibromyalgia (off-label in some cases)

Post-surgical or post-traumatic chronic pain

Tramadol ER Drug Class and Schedule

Tramadol is classified as a centrally acting synthetic opioid analgesic. It works differently from traditional opioids (see our guide on how tramadol works for a full explanation) through a dual mechanism.

The DEA classified tramadol as a Schedule IV controlled substance in August 2014. This means:

It requires a written or electronic prescription — no phone-in refills

Up to 5 refills are allowed within 6 months of the prescription date

It is subject to DEA production quotas, which can affect availability

State prescription drug monitoring programs (PDMPs) track dispensing

Dosage: How Is Tramadol ER Taken?

Tramadol ER tablets come in three strengths:

100 mg

200 mg

300 mg

Starting dose: For patients new to tramadol, the starting dose is 100 mg once daily. The dose is increased by 100 mg every 5 days as needed for pain relief, up to the maximum of 300 mg per day.

Maximum dose: 300 mg once daily. Do not exceed this amount.

How to take it: Swallow the tablet whole with a full glass of water. Do NOT chew, crush, or break the tablet — doing so destroys the extended-release mechanism and releases the full dose at once, which can be dangerous or fatal.

With or without food: Tramadol ER can be taken with or without food, but taking it with food may help reduce nausea.

Who Should NOT Take Tramadol ER?

Tramadol ER is not appropriate for everyone. Tell your doctor if you have any of the following:

History of seizures or epilepsy

Currently taking MAO inhibitors (MAOIs) — tramadol is contraindicated with MAOIs

History of opioid or substance use disorder

Severe hepatic impairment — tramadol ER should not be used

Pregnancy — prolonged use can cause neonatal opioid withdrawal syndrome

Under 18 years of age — not approved for pediatric use
