The white pill imprinted with “IP 110” is a prescription medication commonly used for the management of moderate to severe pain. It is a combination drug that pairs a central-acting opioid agonist with a non-opioid analgesic to achieve an enhanced pain-relieving effect.
Pill Identification
Accurate identification of prescription medication is vital to ensure patient safety and prevent dosing errors.
- Imprint: IP 110
- Active Ingredients: Hydrocodone Bitartrate 10 mg and Acetaminophen 325 mg
- Color: White
- Shape: Oval (capsule-shaped / oblong)
- Score Line: It typically features a bisect or score line on one side, allowing the tablet to be evenly split if a healthcare provider directs a partial dose.
- Manufacturer: Amneal Pharmaceuticals
- Crucial Distinction: While the closely related “IP 109” pill contains 5 mg of hydrocodone, the IP 110 pill contains 10 mg of hydrocodone. Both contain the exact same amount of acetaminophen (325 mg). Because the opioid strength is doubled, mistaking one for the other carries a high risk of accidental overdose.
Mechanism of Action
The IP 110 pill utilizes a dual-mechanism approach to combat pain. By targeting both the central nervous system and peripheral pain pathways, the two active ingredients work synergistically.
Hydrocodone Bitartrate (10 mg)
Hydrocodone is a semisynthetic opioid analgesic.
- Receptor Binding: It acts primarily as an agonist at the opioid receptors (mu-opioid receptors) within the central nervous system (CNS).
- Pain Modulation: Binding to these receptors inhibits descending pain pathways and alters the transmission of nociceptive (pain) signals. This doesn’t eliminate the physical source of the pain, but it fundamentally changes how the brain perceives and emotionally responds to it.
Acetaminophen (325 mg)
Acetaminophen is a non-opioid, non-salicylate analgesic and antipyretic (fever reducer).
- Central Inhibition: While its peripheral actions are limited, acetaminophen is believed to inhibit cyclooxygenase (COX) enzymes in the brain, thereby reducing prostaglandin synthesis. Prostaglandins are chemicals that sensitize pain receptors.
- The Synergy: By reducing the intensity of pain signals reaching the brain, acetaminophen allows the hydrocodone component to work more effectively, providing superior pain control than either drug would achieve alone at these doses.
Dosage and Administration
Because of the high potency of the 10 mg hydrocodone component, dosing must be strictly supervised and tailored to the individual patient by a licensed healthcare provider.
- Typical Adult Dosage: The standard dose is 1 tablet every 4 to 6 hours as needed for severe pain.
- Maximum Acetaminophen Ceiling: The absolute maximum daily limit of acetaminophen for an adult is 4,000 mg (4 grams) in a 24-hour period to prevent severe liver damage.
- Maximum Daily Pill Limit: For the IP 110 formulation, the absolute daily limit is 6 tablets in 24 hours (which delivers 1,950 mg of acetaminophen and 60 mg of hydrocodone). Note: While 6 tablets are well below the acetaminophen ceiling, going higher introduces an extreme risk of dangerous opioid toxicity due to the 60 mg hydrocodone cumulative total.
- Administration: Tablets must be swallowed whole with a full glass of water. They can be taken with food to mitigate potential stomach upset. Never crush, chew, or dissolve an IP 110 pill, as doing so causes a rapid release of the entire 10 mg dose of hydrocodone, which can cause sudden, fatal respiratory depression
Side Effects
Side effects can range from standard bodily adjustments to severe, life-threatening medical emergencies.
Common Side Effects
These effects are common and should be reported to a doctor if they persist or worsen:
- Drowsiness, sedation, or severe dizziness
- Constipation (very common with opioid use; preventative stool softeners are often recommended)
- Nausea and vomiting
- Mild itching (pruritus) or skin flushing
- Dry mouth
Serious Side Effects
Seek immediate emergency medical care if any of the following symptoms develop:
- Respiratory Depression: Slow, shallow, faint, or labored breathing.
- Profound Hypotension: A dangerous drop in blood pressure, resulting in fainting or severe lightheadedness upon standing.
- Adrenal Insufficiency: Symptoms include chronic fatigue, muscle weakness, loss of appetite, and severe nausea.
- Serotonin Syndrome: Agitation, hallucinations, rapid heart rate, shivering, or severe muscle twitching (typically occurs when mixed with certain antidepressants).
Boxed Warnings (FDA Alerts)
As a Schedule II controlled substance, the IP 110 pill carries the US Food and Drug Administration’s (FDA) highest level of warnings due to its severe safety risks.
FDA Black Box Warnings
- Addiction, Abuse, and Misuse: Hydrocodone exposes users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death.
- Life-Threatening Respiratory Depression: Serious, life-threatening, or fatal respiratory depression may occur, particularly when first starting the medication or following a dose increase.
- Accidental Ingestion: Accidental ingestion of even one dose of IP 110, especially by a child, can result in a fatal hydrocodone overdose.
- Neonatal Opioid Withdrawal Syndrome (NOWS): Prolonged use of this medication during pregnancy can result in life-threatening opioid withdrawal symptoms in the newborn baby.
- Interaction with CNS Depressants & Alcohol: Concomitant use of opioids with benzodiazepines, muscle relaxants, or alcohol may result in profound sedation, respiratory depression, coma, and death.
- Severe Hepatotoxicity: The acetaminophen component has been linked to acute liver failure, sometimes resulting in liver transplantation or death. This is almost always caused by exceeding the 4,000 mg daily limit or mixing multiple medications that contain acetaminophen.
Precautions and Contraindications
Absolute Contraindications
Do not take IP 110 if you have:
- Significant respiratory depression, acute or severe bronchial asthma, or hypercapnia (high carbon dioxide levels in the blood).
- A known or suspected gastrointestinal obstruction, specifically paralytic ileus (paralyzed bowel).
- A known hypersensitivity or severe allergic reaction to hydrocodone, acetaminophen, or any other opioid.
Critical Safety Precautions
- The “Hidden” Acetaminophen Hazard: Thousands of over-the-counter (OTC) medications for cough, cold, allergies, and sleep contain hidden acetaminophen. Taking these alongside IP 110 can quickly cause an accidental overdose, damaging or destroying liver tissue. Always cross-check active ingredient labels.
- Pre-existing Conditions: Patients with liver disease, kidney impairment, thyroid disorders, or a personal/family history of substance use disorder require intense monitoring and lowered dosages, if prescribed at all.
- Activities Requiring Alertness: Do not drive, operate heavy machinery, or engage in hazardous tasks while taking IP 110, as the mental clouding and slowed reflexes severely impair motor skills.
