This requires them to increase their drug dosage to maintain the benefit, and that in turn also increases the unwanted side effects. [78] Long-term opioid use can cause opioid-induced hyperalgesia, which is a condition in which the patient has increased sensitivity to pain. [101] All of the opioids can cause side effects. [70]
A 2016 Cochrane review (updated in 2021) found little difference in benefit between hydromorphone and other opioids for cancer pain. [10] Common side effects include dizziness, sleepiness, nausea, itchiness, and constipation. [7] Serious side effects may include abuse, low blood pressure, seizures, respiratory depression, and serotonin syndrome ...
Oxymorphone (sold under the brand names Numorphan and Opana among others) is a highly potent opioid analgesic indicated for treatment of severe pain. Pain relief after injection begins after about 5–10 minutes, after oral administration it begins after about 30 minutes, and lasts about 3–4 hours for immediate-release tablets and 12 hours for extended-release tablets.

Overdose can result in severe respiratory depression or collapse and death. The ethanol component can also induce adverse effects at higher doses; the side effects are the same as with alcohol. Long-term use of laudanum in nonterminal diseases is discouraged due to the possibility of drug tolerance and addiction.
Its effects last for about four to six hours. Codeine exhibits abuse potential similar to other opioid medications, including a risk of addiction and overdose. [4] Common side effects include vomiting, constipation, itchiness, lightheadedness, and drowsiness. [4] Serious side effects may include breathing difficulties and addiction. [4]
This is a list of opioids, opioid antagonists and inverse agonists. Opium and poppy straw derivatives ... Dibenzoylmorphine (first designer drug)
Mixed agonist-antagonist opioids, such as nalbuphine, serve as a classic example of the ceiling effect; increasing the dose of a narcotic frequently leads to smaller and smaller gains in relief of pain. In many cases, the severity of side effects from a medication increases as the dose increases, long after its therapeutic ceiling has been reached.
The drug can be made from codeine and iodine derived from over-the-counter medications and red phosphorus from match strikers, [17] in a process similar to the manufacturing of methamphetamine from pseudoephedrine. Like methamphetamine, desomorphine made this way is often contaminated with various agents.
