Levorphanol Tablet: Uses, Dosage, Side Effects, Precautions and Alternates
| Generic name | Levorphanol tartrate |
|---|---|
| Drug class | Opioid analgesic |
| Forms | Oral tablet (2 mg), Oral tablet (3 mg) |
Quick overview
Levorphanol Tablet (levorphanol tartrate) is an opioid analgesic used to manage pain severe enough to require an opioid, especially when other treatments are not effective enough or cannot be tolerated. It works on opioid receptors in the brain and spinal cord to change how the body senses and responds to pain. It is a strong prescription medicine that must be used exactly as directed due to serious risks, including addiction, overdose, and life-threatening breathing problems.
What is Levorphanol Tablet
Levorphanol is an opioid medicine that is used to treat moderate to severe pain. It is a strong prescription pain medicine that contains an opioid (narcotic).
Levorphanol Tablet uses
- Management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate
- Used when other pain treatments such as non-opioid pain medicines do not treat pain well enough or cannot be tolerated
Benefits of Levorphanol Tablet
- Provides relief from severe pain that requires an opioid analgesic.
- Helps reduce pain intensity when non-opioid treatments are inadequate or not tolerated.
- Can be used for acute or persistent severe pain when a clinician determines opioid treatment is appropriate.
- Has a longer duration of action than some other opioid pain medicines, which may be useful in selected chronic-pain patients.
- May improve comfort and daily functioning when severe pain is adequately controlled.
How Levorphanol Tablet works
Levorphanol acts on opioid receptors in the brain and spinal cord to change how the body feels and responds to pain.
Levorphanol Tablet dosage
Follow the directions on your prescription label and read all medication guides. Never use levorphanol in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of levorphanol. Do not stop using levorphanol suddenly after long-term use without talking to your doctor, since this could cause serious withdrawal symptoms. Never crush or break a levorphanol pill to inhale the powder or mix it into a liquid to inject the drug.
Take your prescribed dose on a regular schedule as needed for pain, and do not take more than prescribed. If you miss a dose, skip it if it is almost time for your next dose; do not take two doses at one time. For short-term (acute) pain, you may only need to take it for a few days. Older adults may need a reduced starting amount and should be monitored closely by their doctor.
