Ultracet: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions
What Is Ultracet?
Ultracet is a prescription pain-relief medication that combines two active ingredients:
- Tramadol hydrochloride – an opioid pain reliever.
- Acetaminophen (paracetamol) – a non-opioid pain reliever and fever reducer.
A common Ultracet tablet contains:
- Tramadol 37.5 mg
- Acetaminophen 325 mg
The exact formulation may vary by country.
Ultracet is used for the short-term management of certain types of pain when other pain-relief options may not provide enough relief. Because it contains tramadol, it carries risks including dependence, misuse, and serious side effects if not used correctly.
How Ultracet Works

Ultracet works through the combined effects of its two ingredients:
Tramadol
Tramadol works by:
- Changing how the brain and nervous system process pain signals.
- Activating opioid receptors involved in pain control.
- Affecting serotonin and norepinephrine pathways that influence pain perception.
Acetaminophen (Paracetamol)
Acetaminophen helps:
- Reduce pain.
- Lower fever.
- Enhance the pain-relieving effect of tramadol.
Together, these ingredients provide stronger pain relief than either medicine alone for some patients.
Ultracet Uses
Ultracet may be prescribed for:
Moderate Pain
Examples may include:
- Short-term pain after procedures.
- Injury-related pain.
- Certain musculoskeletal pain conditions.
