Is gabapentin a narcotic/controlled substance?

The anti-seizure medication gabapentin is not currently considered a narcotic or controlled substance by the federal government, but certain states have enacted legislation so that the medication is treated as one or monitored by the state’s prescription drug monitoring program.

The use of a controlled substance is regulated by the federal government to prevent abuse or misuse. Prescription drug monitoring programs track prescriptions of certain medications to flag individuals who may be misusing them and at risk of an overdose.

In addition to preventing seizures in individuals with epilepsy, gabapentin may be prescribed to treat nerve or neuropathic pain caused by herpes virus or shingles in adults.

Gabapentin may be considered as an alternative to opioids, which can be highly addictive and result in overdoses and death. Often prescribed to treat pain, opioids are a controlled substance. Gabapentin is known as an opioid potentiate because it can increase the high felt with opioids such as fentanyl, oxycodone, hydrocodone, codeine, morphine and even the street drug heroin.

As a result, gabapentin has potential for misuse or abuse. The combination of opioids and gabapentin may increase the risk of dying from an overdose likely due to depressed breathing. Individuals with chronic obstructive pulmonary disease (COPD) and the elderly are at greatest risk of dying from this combination.

Gabapentin Dosage Chart, Gabapentin Dosage for Adults and Gabapentin Dosage for Children

Gabapentin is a generic prescription drug that is FDA-approved as an add-on treatment with other medications for partial seizures in those with epilepsy.

It can also be used to treat nerve pain from postherpetic neuralgia (a complication of shingles). Gabapentin is frequently prescribed off-label for many other conditions, such as diabetic peripheral neuropathy, fibromyalgia, and alcohol dependence.

Gabapentin is typically prescribed as a generic, but the drug is also available under the brand names Neurontin and Gralise. Some patients may be prescribed drugs very similar to gabapentin—such as Horizant (gabapentin enacarbil) or Lyrica (pregabalin)—instead of gabapentin.

Gabapentin is taken as a tablet, capsule, or oral liquid. Dosing will depend on the condition being treated, age of the person being treated, and kidney function. The usual dose for epilepsy starts at 300 mg on the first day. The dose can then be increased until an effective dose is reached, which is usually 300 to 600mg taken three times per day.

The recommended dose is 5-10 mg per kilogram of body weight (2.3-4.5 mg/lb) every 12 hours, but dosing will vary between veterinarians.

As with people, the dose may start small and steadily increase until an effective dose is reached.

What should you know before you buy gabapentin Online

Gabapentin (Generic Neurontin ) was developed to treat epilepsy, but it is now used to treat various forms of chronic pain. It works by reducing the number of signals sent through the nerves. If the signals are reduced then the pain will be reduced. Research has shown that Gabapentin can help in treating various types of nerve pain.

Some Research Team performed searches to look for clinical trials where gabapentin was used to treat neuropathic pain or fibromyalgia. They found that 5633 participants had been involved in 37 studies of reasonable quality.  They tested gabapentin against placebo for four weeks or more.  Studies lasting only one or two weeks are unhelpful when pain can last for years.

Neuropathic pain is pain coming from damaged nerves. It differs from pain messages carried along healthy nerves from damaged tissue (a fall, cut, or arthritic knee). Neuropathic pain is treated by different medicines than pain from damaged tissue.

Medicines like paracetamol or ibuprofen are not effective in neuropathic pain, while medicines that are sometimes used to treat depression or epilepsy can be very effective in some people with neuropathic pain.  Our understanding of fibromyalgia (a condition of persistent, widespread pain and tenderness, sleep problems, and fatigue) is poor, but fibromyalgia can respond to the same medicines as neuropathic pain.

Gabapentin is helpful for some people with chronic neuropathic pain or fibromyalgia. Gabapentin comes as a capsule, tablet, or solution. You take it by mouth. Gabapentin is available as the brand-name drugs Neurontin, Gralise, and Horizant.  It’s also available as a generic drug.

Exposure to drugs, alcohol, toxins Neuropathic Pain Surgical procedures/ Amputation Traumatic Nerve injury/ compression Metabolic disturbance Viral infection Neuropathic pain is a disease, like myocardial infarction is a disease. Myocardial infarction may be caused by smoking, or hypertension, or diabetes. Multiple different things contribute to the cause of myocardial infarction, but myocardial infarction is the disease. Similarly, neuropathic pain is a disease, and this slide shows many of the different conditions that can result in neuropathic pain.

But the pain is nonprotective. It is something that persists and behaves separately as a disease itself. Cancer related (disease or treatment Vascular related neurodegenerative Nutritional deficiency

The best drug you can take is the fast acting Gabapentin and one of the main reasons why many people who do have Diabetic Neuropathy will take that drug is that it is not only fast acting as mentioned but it is also a very low cost drug to purchase too.
