A white oblong tablet stamped IP 109 is hydrocodone 5 mg with acetaminophen 325 mg. The two imprints made next to it in the same series look the same and are not the same tablet.
IP 109, IP 110 and IP 111 are all white, all capsule-shaped, and all hydrocodone with acetaminophen. What changes between them is not visible.
What an IP 109 Pill Is
IP 109 is a generic hydrocodone and acetaminophen tablet, the combination once sold under the brand names Vicodin and Lortab. Nearly every prescription filled now is generic, which is why a manufacturer code is what you find on the tablet instead of a brand name.
Hydrocodone is an opioid and changes how the nervous system registers pain. Acetaminophen works through a separate route and also lowers fever. Together they relieve pain better than either does alone at the same dose.
Because it contains hydrocodone, IP 109 is a Schedule II controlled substance under federal law, the same category as oxycodone and morphine.
The IP 109, IP 110 and IP 111 Series
One manufacturer numbers its hydrocodone and acetaminophen tablets in sequence. Three of them are in circulation, and all three are white and capsule-shaped.
IP 109 is 325 mg of acetaminophen with 5 mg of hydrocodone. IP 110 is 325 mg with 10 mg. IP 111 is 500 mg with 5 mg.
Reading across that list, IP 109 and IP 110 hold the acetaminophen steady and double the opioid. IP 109 and IP 111 hold the opioid steady and raise the acetaminophen by 175 mg. Neither change shows up in the tablet.
This is the practical problem with the series. Someone who knows their prescription as "the white oblong one" has no way to catch a mix-up, because that description fits all three.
How to Confirm Which One You Have
Read the imprint under good light and compare it against the strength printed on the prescription label. The label states both amounts, so a bottle labeled 5 mg with IP 110 tablets inside, or the reverse, is a reason to call the pharmacy before taking any of them.
Shape and color will not help. All three tablets in the series share both.
A loose tablet with no bottle and no label cannot be confirmed by looking at it. A pharmacist can identify it without an appointment and without a charge.
Other Imprints Carrying the Same Drug
IP 109 is not the only tablet that is hydrocodone 5 mg with acetaminophen 325 mg. M365 is the same combination at the same strength from a different manufacturer, and it is also white and capsule-shaped.
That matters when a prescription is refilled and the pharmacy has switched suppliers. The tablet in the new bottle looks different, carries a different code, and is the same medication at the same dose. That is a normal substitution rather than an error, though it is worth confirming with the pharmacist rather than assuming.
The M series has the same internal problem the IP series does. M365 is 5 mg, M366 is 7.5 mg and M367 is 10 mg, all with 325 mg of acetaminophen, and M365 and M367 are both white and capsule-shaped.
IP 109 Dosage and Daily Limits
The usual adult dose at the 5 mg and 325 mg strength is 1 to 2 tablets by mouth every 4 to 6 hours as needed for pain, with a maximum of 8 tablets in 24 hours.
At the 10 mg strength the dose drops to 1 tablet every 4 to 6 hours with a maximum of 6 tablets, because the opioid per tablet has doubled.
Total daily acetaminophen from every source should stay under 4 grams. Eight IP 109 tablets contribute 2,600 mg, which leaves room but not much once cold and flu products, sleep aids and over-the-counter pain relievers are counted. Many of those contain acetaminophen without saying so on the front of the package.
Side Effects Worth Separating
The side effects people report most often with hydrocodone combination products are nausea, vomiting, stomach pain, increased sweating, and reduced sexual desire or difficulty with erections. Those are the ones to mention to a prescriber if they are severe or do not settle.
A different and shorter list calls for immediate medical attention rather than a phone call. Slowed breathing, long pauses between breaths, shortness of breath, extreme drowsiness, seizures, chest pain or changes in heartbeat, and swelling of the face, mouth, tongue or throat all belong in that group.
Drowsiness and slowed reaction time make driving and operating machinery unsafe while taking the medication.
Overdose Signs and What to Do
Hydrocodone overdose works by slowing breathing until it becomes dangerously weak or stops. The risk climbs sharply when an opioid is combined with alcohol, benzodiazepines, sleep medication or anything else that depresses breathing.
The warning signs are slow or shallow breathing, difficulty waking, extreme sleepiness, confusion, pinpoint pupils, blue or gray lips, and cold or clammy skin.
Call 911. Naloxone can reverse the opioid effect and restore breathing, but it can wear off before the opioid has cleared the body, so medical monitoring still matters after someone wakes up.
The acetaminophen side carries a separate danger that is easier to miss. Liver injury from acetaminophen can begin with nothing more than nausea and unusual tiredness, hours before anything looks like an emergency.
Counterfeit Tablets Stamped IP 109
Counterfeit pills pressed to look like prescription opioids are widespread, and hydrocodone imprints are copied along with the rest.
A counterfeit reproduces the imprint, the color and the shape. What is inside is unrelated to what the stamp says, and fentanyl is often what is inside. The amount varies from tablet to tablet within a single batch, so one pill from a bag being survivable says nothing about the next one.
No visual inspection separates a counterfeit from a real tablet. Provenance is the only reliable signal. A tablet dispensed by a pharmacy against your own prescription is what it says it is. Anything else is unidentified.
When Hydrocodone Use Has Moved Past the Prescription
Physical dependence on an opioid taken as directed is expected and is not the same thing as addiction. Tolerance builds, and stopping suddenly after regular use brings restlessness, muscle pain, insomnia, nausea, vomiting and diarrhea. That happens to people following the label exactly.
What signals a change is behavior. Running out early. Taking a dose for something other than pain. Crushing or altering tablets. Using someone else's prescription. Seeing more than one prescriber. Continuing after the injury or procedure that started it has healed.
Nobody who has been on an opioid regularly should stop on their own. A prescriber lowers the dose gradually, and that taper is what keeps withdrawal manageable.
