Postoperative pain (short course)	5 mg/325 mg every 4–6 hours as needed	Limit to 3–7 days when possible; re-evaluate before refilling

Side Effects

Common side effects may include:

• Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Hydrocodone is a CYP3A4 and CYP2D6 substrate; acetaminophen is hepatotoxic in overdose or with chronic alcohol use.

Benzodiazepines and other CNS depressants (alcohol, zolpidem, gabapentin, pregabalin, sedating antihistamines): Concurrent use causes additive respiratory depression, profound sedation, coma, and death. An FDA Boxed Warning applies. Avoid combination when possible; if necessary, prescribe the lowest effective doses for the shortest duration.
Other acetaminophen-containing products (Tylenol, multi-symptom cold medicines, other prescription combinations): Risk of inadvertent acetaminophen overdose and acute liver failure. Total acetaminophen from all sources should not exceed 4,000 mg/day (3,000 mg/day for chronic use or in elderly, alcohol use, or hepatic impairment).
Strong CYP3A4 inhibitors (ritonavir, ketoconazole, clarithromycin, grapefruit juice): Increase hydrocodone concentrations, raising the risk of fatal respiratory depression. Reduce dose and monitor closely.
Strong CYP3A4 inducers (rifampin, carbamazepine, phenytoin): Decrease hydrocodone concentrations, potentially reducing analgesia and precipitating withdrawal in dependent patients.
Serotonergic agents (SSRIs, SNRIs, triptans, MAOIs, tramadol): Increase the risk of serotonin syndrome. Monitor for agitation, hyperthermia, tachycardia, clonus, and altered mental status; discontinue hydrocodone if suspected.
Warfarin: Acetaminophen can enhance the anticoagulant effect of warfarin, particularly at doses above 2 grams per day for several consecutive days. Monitor INR more frequently during use.

Frequently Asked Questions

The acetaminophen provides additional, non-opioid pain relief through a different mechanism, allowing a lower hydrocodone dose to achieve the same analgesic effect. This combination strategy reduces opioid-related side effects and may lower addiction potential — but it also creates risk of accidental acetaminophen overdose if other acetaminophen-containing products are taken simultaneously.

For most adults, the maximum is 4,000 mg per day from all sources combined, but many clinicians recommend a more conservative 3,000 mg per day, especially with chronic use or in older adults. Each 5 mg/325 mg hydrocodone-acetaminophen tablet contains 325 mg of acetaminophen, so even modest doses leave little room for additional acetaminophen-containing products.

Most acute pain episodes resolve within 3 to 7 days, and current CDC guidance recommends limiting opioid prescriptions for acute pain to that duration whenever possible. Use beyond a week increases the risk of dependence and adverse effects without proportional pain benefit. Discuss alternative or transition strategies with your provider before refilling.

This medication is taken as needed for pain rather than on a fixed schedule, so there is no "missed dose" concept. Take the next dose when pain returns and at least 4 hours have passed since the previous dose. Do not double up. If pain remains severe despite appropriate dosing, contact your prescriber.

Store in a locked location out of reach of children, teenagers, pets, and visitors — accidental ingestion can be fatal. When no longer needed, dispose of unused tablets at a DEA-authorized drug take-back location, a community drug drop-box, or by following FDA flush-list instructions. Do not keep leftover opioids "just in case."
