Can You Identify Fake Dilaudid?
Common signs that a drug is counterfeit include:
- variations in color, size, shape, or texture
- errors in the font or lettering
- unusual packaging
- strange taste
Only use pain medication prescribed by a licensed healthcare professional and dispensed at a legitimate pharmacy.
Any Dilaudid purchased on the street, from sketchy online pharmacies or dark web sites, or handed off from an acquaintance could be dangerous fakes made with fentanyl or other unknown ingredients.
The only way to identify fake Dilaudid is by using a fentanyl test kit or another drug test kit to identify the substances in the illicit product.

Dilaudid Overdose
If Dilaudid is taken without a prescription, or if you take more of the medication than directed, it may lead to a hydromorphone overdose. And, mixing hydromorphone with alcohol, benzodiazepines, or other opiates like codeine, hydrocodone, or oxycodone also increases your risk of overdose.
As a strong central nervous system (CNS) depressant, Dilaudid can generate opioid overdose signs and symptoms such as:
- severe drowsiness/sedation
- impaired motor control
- mental confusion
- pinpoint pupils
- cold, clammy skin
- blue-colored lips and fingernails nails
- gurgling or gasping
- breathing problems, including stopped, slow, or shallow breathing
- slow heart rate
- low blood pressure
- becoming unresponsive or losing consciousness
Dilaudid overdoses and the respiratory depression they cause are dangerous, life-threatening medical emergencies. If you suspect an overdose has occurred, contact 911 and provide first-aid until help arrives, including the use of the opioid antidote naloxone (Narcan) if it is available.
