Looking for a tramadol HCl ER biphasic coupon? Tramadol hydrochloride extended-release (biphasic) is a generic, once-daily opioid pain medicine (originally sold as Ryzolt, and related to the discontinued Ultram ER and to ConZip). Because it is a generic, it is already among the lower-cost options in its class, but the cash price can vary widely from one pharmacy to the next, so comparing before you fill matters. Rx.com compares prices across more than 60,000 pharmacies so you can find today's lowest price near you. Enter your ZIP above to see today's price at pharmacies in your area, then show the coupon at the counter.
What is tramadol HCl ER biphasic and how does it work?
Tramadol hydrochloride extended-release (biphasic) is an opioid (narcotic) analgesic that also acts as a serotonin-norepinephrine reuptake inhibitor. The biphasic extended-release formulation (originally branded Ryzolt) combines an immediate-release component with an extended-release component in a single once-daily tablet, so the medicine is released gradually over 24 hours.
It is FDA-approved for the management of moderate to moderately severe chronic pain in adults who need around-the-clock, long-term opioid treatment and for whom other treatment options are not adequate. It is not intended for as-needed (PRN) pain, mild or short-term pain, or acute pain. This information is educational and is not a substitute for advice from your doctor or pharmacist.
Tramadol ER cost and how to save without insurance
Tramadol extended-release is available as a generic, which usually makes it one of the more affordable choices in its category. Even so, the cash price you pay without insurance can differ significantly depending on which pharmacy you use, which is exactly why comparing is worth it. Prices change often and are shown live on this page, so enter your ZIP above to see today's price near you and use the Rx.com coupon at checkout.
There is no manufacturer savings card for this generic. Rx.com's discount pricing is available whether or not you have insurance, and in some cases the coupon price may be lower than an insurance copay, so it is worth comparing both.
Related medicines and alternatives
Tramadol comes in several forms and combinations. If your prescription is written differently, or you want to compare options with your prescriber, these related pages may help:
- tramadol and tramadol HCl — the standard immediate-release forms
- ConZip and Ultram ER — brand extended-release versions of tramadol
- tramadol-acetaminophen — a combination product
Only your prescriber can decide which form and strength is right for you. Do not switch products on your own, since extended-release and immediate-release tramadol are not interchangeable.
Important safety information
Tramadol ER carries FDA boxed warnings for addiction, abuse, and misuse (which can lead to overdose and death); life-threatening respiratory depression; and the risk that accidental ingestion, especially by a child, can be fatal. It should not be used in children under 12, or for pain after tonsil or adenoid surgery in anyone under 18, because some people metabolize it ultra-rapidly (CYP2D6). Combining it with benzodiazepines or other central nervous system depressants can cause profound sedation, respiratory depression, coma, and death. Prolonged use during pregnancy can cause neonatal opioid withdrawal syndrome.
Other important risks include dose-related seizures, serotonin syndrome (especially with SSRIs, SNRIs, or MAOIs), suicide risk, adrenal insufficiency, and severe low blood pressure. Tablets must be swallowed whole and must never be cut, crushed, chewed, or dissolved. Tramadol ER is subject to an opioid REMS program. This is not a complete list of warnings, and this page is not medical advice. Talk with your doctor or pharmacist about your full health history and all other medicines you take before starting or changing this medication.
