Description
Hydrocodone 7.5/325mg is a prescription pain medication combining Hydrocodone bitartrate (7.5 mg), a semi-synthetic opioid, with Acetaminophen (325 mg), a non-opioid pain reliever and fever reducer.
This formulation offers moderate to moderately strong pain relief through two mechanisms:
-
Hydrocodone: Acts on opioid receptors in the brain and spinal cord to reduce the sensation and emotional response to pain.
-
Acetaminophen: Enhances the pain-relieving effects and lowers fever.
Hydrocodone 7.5/325mg is one of the most commonly prescribed mid-strength opioid combinations, offering effective pain management with reduced acetaminophen exposure compared to older high-dose formulations.
Features
-
Each tablet contains 7.5 mg of Hydrocodone and 325 mg of Acetaminophen.
-
Provides dual-action analgesia combining opioid and non-opioid mechanisms.
-
Available under brand names such as Norco® 7.5/325, Lortab® 7.5/325, and Vicodin® ES.
-
Lower acetaminophen content (325 mg) meets FDA safety guidelines, reducing the risk of liver toxicity.
-
Typically prescribed for short-term pain management when non-opioid analgesics are insufficient.
Uses
-
Relief of moderate to moderately severe pain, such as:
-
Postoperative or injury-related pain
-
Dental pain
-
Musculoskeletal conditions
-
-
Sometimes used in chronic pain management, under close medical supervision.
-
Intended for short-term or intermittent use due to risk of tolerance and dependence.
Effects
Therapeutic Effects
-
Hydrocodone: Alters pain perception and response within the central nervous system (CNS).
-
Acetaminophen: Enhances analgesic effect and reduces fever.
-
The combination produces synergistic pain relief and rapid onset of action.
Possible Side Effects
-
Common: Drowsiness, dizziness, nausea, vomiting, constipation, or lightheadedness.
-
Serious: Respiratory depression, severe drowsiness, confusion, allergic reactions, or liver damage (especially if combined with alcohol or excessive acetaminophen intake).
Precautions
-
Use only as prescribed by a licensed healthcare provider.
-
Avoid alcohol, sedatives, and other CNS depressants, which can increase the risk of respiratory failure.
-
Do not exceed 4,000 mg of acetaminophen per day (including other medications).
-
Use with caution in patients with liver disease, breathing problems, or history of substance misuse.
-
May cause dependence or withdrawal symptoms with long-term use; taper gradually if discontinuing.
Important Note
Hydrocodone 7.5/325mg is a Schedule II controlled substance (U.S.), indicating a high potential for abuse and dependence.
This strength complies with FDA guidelines limiting acetaminophen to 325 mg per tablet, making it safer than discontinued higher-acetaminophen versions (e.g., 7.5/500mg or 7.5/750mg).
Always store in a secure place, use only under medical supervision, and keep out of reach of children or unauthorized users.
