How Long Does Morphine Stay in the Body?. Watson

How long morphine is detectable in the body depends on many variables, including which kind drug test is being used. Morphine - also known as Roxanol, Dover's Powder, Paregoric, Laudanum, Morphine, Roxanol, Roxanol SR, Robitussin A-C, Avinza, MSContin, Oramorph Morf - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting morphine in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time morphine will show up on a drug test.

Other factors that may affect how long morphine remains in the system is the frequency the medication was taken, the length of time it was used, and the strength of the dosages.

The following is an estimated range of times, or detection windows, during which morphine can be detected by various testing methods:

How Long Does Morphine Stay in Urine?

Morphine can be detected in a urine test for up to 3-4 days

How Long Does Morphine Remain in the Blood?

Blood tests for Morphine can detect the drugs for up to 12 hours

How Long Can Morphine Be Detected in Saliva?

A saliva test can detect Morphine for 1-4 days

How Long Does Morphine Remain in Hair?

Morphine, like like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

Preventing a Morphine Overdose

Morphine is in a class of medications known as opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.

It is prescribed to relieve moderate to severe pain.

Morphine is usually prescribed for 24-hour relief of pain that cannot be controlled by other pain medications.

Knowing how long morphine remains in the system can help prevent an accidental overdose by taking more of the medication too soon.

Some symptoms of morphine overdose include:

In case of an morphine overdose, call 9-1-1 or the poison control center at 1-800-222-1222. First-responders should be able to revive the victim with Narcan, but only if they are notified soon enough.
