What is M367?

M367 is basically a painkiller useful in relieving mild to acute pains.  It is a prescription drug classified under the Narcotic Analgesic Combinations drugs. This medicine comes in the form of tablets with its name M367 printed on it.  Hydrocodone (10 mg) and Acetaminophen (325 mg) are its key ingredients. It has been categorized by the Food and Drug Administration (FDA) under Pregnancy Category C drug and graded as a Schedule 2 controlled substance by the Controlled Substance Act (CSA).

Acetaminophen, commonly known as Paracetamol, a fever and pain reliever used for menstruation pains, osteoarthritis, backaches, flu and cold pains and aches, toothaches and headaches also have the M367 mark. It is available in the form of an oral solution and oral tablet. When all other painkillers fail to relieve the patient of their intense pain, Acetaminophen-hydrocodone oral tablet is prescribed.  It is very instrumental in treating mild to critical pain.

Why is M367 Used?

M367 is a prescription drug advised by physicians for relieving certain medical problems such as:

  • Rheumatoid arthritis
  • Severe back pain
  • Cough
  • Any other general pain

M367 is a combination medication used to relieve mild to acute pain. It is made up of a narcotic (Opioid) pain reliever HYDROCODONE and a non-opioid pain reliever ACETAMINOPHEN.  Hydrocodone impacts the brain to help the body respond to the medicine while Acetaminophen can help in bringing down a fever.

Within 1.5 hours, it begins to show its effect and this generally lasts for about 4 – 6 hours, though the duration may vary from one patient to another depending on many factors.  This drug may also be used to treat chronic pain, chronic cough, a variety of cancer-related pains and arthritic pains.

It can be taken either all by itself or in combination versions of each drug to make a specific narcotic analgesic. The upside of such combination medication is they help to soothe a person’s frame of mind, which allows the painkiller enough time to work and show the results. Hydrocodone is also sometimes mixed with antihistamines to form a syrup that helps keep an aggravating cough in check and provide relief from the ensuing pain linked with coughing.

Recommended Dosage of M367

The dosage, the frequency of the drug, and the drug form are entirely dependent on certain aspects like the age of the patient, the condition being treated, other medical conditions you have, the severity of your condition, body mass and your reaction to the first dose.

It is suggested to seek advice from the doctor regarding proper dosage and assessment as this medicine could lead to an addiction if taken in higher doses for a long period of time. Changes in dosage should not be made on a whim. It is always wise to follow the doctor’s recommendation diligently. M367 is used for both short and long-term treatment and could be detrimental to your health if not taken precisely as advised by the physician.

Discontinuation of the drug or not taking it at all may make your pain even worse. For this medicine to perform as it should, a specific amount needs to be in your system continually. If not, your medication may not do the job as well as it needs to or may even cease working totally. In case you are taking the medication properly at the prescribed timings you can take a missed dose immediately. However, if it is almost time for your next scheduled dose, then you should forego the missed dose. You need not take extra doses to make up for the missed one as it could lead to damaging side effects.

On the other hand if you take in excess of the prescribed dose you are in danger of overdosing and may experience symptoms like slow heartbeat, slowed breathing, sweating, liver damage, lethargy, weak pulse, extremely low blood pressure, muscle weakness, dark urine, vomiting, possible coma, extreme drowsiness, pinpoint pupils, cold and clammy skin, blue lips and fainting.

Hence, you should let your doctor know if you are already pregnant or planning to conceive in the near future.

M367, though a very effective pain reliever, can also cause much harm if taken for a period of time. It could be habit forming leading to narcotic abuse, misuse and in most cases addiction that could be quite fatal.  Therefore, it should only be used by the patient concerned and no one else.

This medication should be stored in a safe place beyond the reach of others. Maintain a record of the number of tablets that have been used from each new bottle. As a medicine, M367 can also be misused and abused and hence, keep yourself aware if any member in your family is taking this medicine without the knowledge of others or without an authentic prescription.

Since it is prone to causing side effects, it may weaken your thought process and normal responses.

In order to help prevent constipation while you are taking M367, consume 6 – 8 full glasses of water on a daily basis.  Try to increase the fiber in your food by taking the good advice of your doctor. Do not use a laxative (stool stimulant) without the permission of your doctor.

It is advised not to use any other over-the-counter allergy, cold, painkiller or cough medication without consulting your doctor. Since M367 is contained in many medicines available at the neighborhood pharmacy, it is likely you may take too much of other products along with it which could be really risky. You must, therefore, read the label carefully of any other medicine you intend to take to see if it contains M367.
