Morphine is a narcotic commonly used to relieve pain. The use of morphine in treatment requires a doctor's opinion to avoid risks and unwanted side effects.1. Why is Morphine Prescribed?
The use of opiates for pain relief has been used for a long time. Humans started using opium around 3500 BC. Through the ages, it has come to be known as a universal remedy.
In 1803, morphine was isolated from opium poppy, and it became one of the first drugs made from this plant. Morphine is popular and widely used for all types of pain relief. But one soon found its side effect of dependence on it.
Morphine and other narcotics have serious side effects. Therefore, it must be understood very well before giving it to the patient to minimize the risks that the patient may face.
According to the Centers for Disease Control and Prevention (CDC), about 11% of adults in the United States experience attacks of pain every day. Studies show that 10 to 60 percent of Americans undergo common surgeries and experience chronic pain after the procedures.
These pains affect their daily life and health. Morphine is used to relieve acute (immediate) and chronic (lasting) pain. However, morphine has serious side effects. Therefore, doctors will have to look very carefully every time they prescribe it, because the side effects that Morphine causes other health problems are very large.
There are four types of opioid receptors in several areas of the body. These include receptors in the brain, gastrointestinal (GI) tract, and spinal cord. In the brain, morphine helps release the neurotransmitter dopamine. This blocks pain signals and creates a pleasant sensation. Therefore, morphine acts as a pain reliever.
2. Types of morphine
Morphine is available in oral and injectable forms. Depending on the level of pain and safety for the patient, the doctor will decide which type to use. Today, the CDC has issued guidelines for the use of Morphine to safely and effectively manage chronic pain. This guide was developed specifically to help reduce the risk of opioid overdose and abuse.
2.1 Oral Morphine Oral Morphine is available in both immediate acting and long acting forms. For chronic pain, doctors often prescribe long-acting products. The doctor will decide which formulation and dosage is best by taking into consideration many factors, such as:
Patient's history with opioid medications Degree and type of pain Patient's age Health conditions other (kidney function, heart or lung problems, sleep apnea, low blood pressure, seizures, stomach problems, etc.) Other medications the patient is taking Other factors, such as sensitivity to morphine

The injectable morphine has more risks than the oral version.

If you have been using morphine for a long time, using naloxone can cause immediate withdrawal symptoms. If a person overdoses on long-acting morphine, they may need multiple doses of naloxone. Although management of morphine poisoning has been done, serious complications can still occur, even with naloxone.
