Take Gabapentin as an Anticonvulsant

Anticonvulsants (also commonly known as antiepileptic drugs or as antiseizure drugs) are a diverse group of pharmacological agents used in the treatment of epileptic seizures. Anticonvulsants are also increasingly being used in the treatment of bipolar disorder and borderline personality disorder, since many seem to act as mood stabilizers, and for the treatment of neuropathic pain.

Anticonvulsants suppress the rapid and excessive firing of neurons during seizures. Anticonvulsants also prevent the spread of the seizure within the brain. Some investigators have observed that anticonvulsants themselves may cause reduced IQ in children.   However these adverse effects must be balanced against the significant risk epileptic seizures pose to children and the distinct possibility of death and devastating neurological sequelaesecondary to seizures.

Anticonvulsants are more accurately called antiepileptic drugs (abbreviated “AEDs”), and are often referred to as antiseizure drugs because they provide symptomatic treatment only and have not been demonstrated to alter the course of epilepsy.

Gabapentin (Neurontin) has been approved as adjunctive therapy in adults with partial seizures with or without secondary generalization . Begin with 300 mg daily; increase to 900 to 1,800 mg daily given every 6 to 8 hours.  Side Effects maybe: Somnolence, fatigue, ataxia, dizziness, gastrointestinal upset, dyspnea.

A gamma-aminobutyric acid (GABA) analog, gabapentin does not interact with GABA receptors. Its mechanism of action is unknown.

Gabapentin is well absorbed orally, circulates mostly unbound in the plasma and is excreted unchanged in the kidneys without appreciable metabolism in the body. Oral bioavailability is approximately 60 percent and is not affected by food. The half-life is five to seven hours and is related to the creatinine clearance. Therefore, excretion is decreased in patients with renal impairment and decreased cardiac function, and in elderly patients. Gabapentin can be removed from the system through hemodialysis.

In clinical studies,  gabapentin was found to be effective in adults with refractory partial seizures and was also effective in preventing the progression of partial seizures to generalized tonic-clonic seizures.

Because gabapentin has no known pharmacokinetic interactions with any other antiepileptic drugs, it is useful in patients taking other antiepileptic medication.

If you are taking the tablets and your doctor directs you to split the tablet in half, take the other half-tablet at your next scheduled dose. Discard half tablets if not used within several days of splitting them. If you are taking the capsules, swallow them whole with plenty of water.

It is very important to follow your doctor’s dosing instructions exactly. During the first few days of treatment, your doctor may gradually increase your dose so your body can adjust to the medication. To minimize side effects, take the very first dose atbedtime.

Take this medication regularly to get the most benefit from it. This drug works best when the amount of medicine in your body is kept at a constant level. Therefore, take gabapentin at evenly spaced intervals at the same time(s) each day. If you are taking this medication 3 times a day to control seizures, do not let more than 12 hours pass between doses because your seizures may increase.

Do not take this medication more often or increase your dose without consulting your doctor. Your condition will not improve any faster and the risk of serious side effects may increase.

Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.

Antacids containing aluminum or magnesium may interfere with the absorption of this medication. Therefore, if you are also taking an antacid, it is best to take gabapentin at least 2 hours after taking the antacid.

Different forms of gabapentin (such as immediate-release, sustained-release, enacarbil sustained-release) are absorbed in the body differently. Do not switch from one form to the other without consulting your doctor.

Tell your doctor if your condition does not improve or if it worsens.

The Horizant brand of gabapentin should not be taken during the day. For best results, take Horizant with food at about 5:00 in the evening.

Both Gralise and Horizant should be taken with food.

Neurontin can be taken with or without food.

If you break a Neurontin tablet and take only half of it, take the other half at your next dose. Any tablet that has been broken should be used as soon as possible or within a few days.

Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

If your doctor changes your brand, strength, or type of gabapentin, your dosage needs may change.Ask your pharmacist if you have any questions about the new kind of gabapentin you receive at the pharmacy.

Do not stop using gabapentin suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor’s instructions about tapering your dose.

Wear a medical alert tag or carry an ID card stating that you take gabapentin. Any medical care provider who treats you should know that you take seizure medication.

Gabapentin can cause you to have a false positive urine protein screening test. If you provide a urine sample for testing, tell the laboratory staff that you are taking gabapentin.

What you should know before you buy Gabapentin online

Keep these considerations in mind if your doctor prescribes gabapentin oral capsule for you.

Before taking gabapentin,

  • tell your doctor and pharmacist if you are allergic to gabapentin, any other medications, or any of the inactive ingredients in the type of gabapentin you plan to take. Ask your pharmacist for a list of the inactive ingredients.
  • you should know that gabapentin is available in different forms that may be prescribed for different uses. Ask your doctor to be sure that you are not taking more than one product that contains gabapentin.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: antidepressants; antihistamines; medications for anxiety; medications that make you feel dizzy or drowsy; medications for mental illness; naproxen (Aleve, Anaprox, Naprosyn, others); opioid (narcotic) medications for pain such as hydrocodone (in Hydrocet, in Vicodin, others), morphine (Avinza, Kadian, MSIR, others), or oxycodone OxyContin, in Percocet, in Roxicet, others); sedatives; medications for seizures; sleeping pills, and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • if you are taking antacids such as Maalox or Mylanta, take them at least 2 hours before you take gabapentin tablets, capsules, or solution.
  • tell your doctor if you have or have ever had lung or kidney disease. If you will be taking the extended-release tablets, also tell your doctor if you need to sleep during the day and stay awake at night.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking gabapentin, call your doctor.
  • if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking gabapentin.
  • you should know that this medication may make you drowsy or dizzy, may slow your thinking, and may cause loss of coordination. Do not drive a car or operate machinery until you know how this medication affects you, and your doctor agrees that it is safe for you to begin these activities.
  • if you are giving gabapentin to your child, you should know that your child’s behavior and mental abilities may change while he or she is taking gabapentin. Your child may have sudden changes in mood, become hostile or hyperactive, have difficulty concentrating or paying attention, or be drowsy or clumsy. Have your child avoid activities that could be dangerous, such as riding a bicycle, until you know how gabapentin affects him or her.
  • remember that alcohol can add to the drowsiness caused by this medication.
  • you should know that your mental health may change in unexpected ways and you may become suicidal (thinking about harming or killing yourself or planning or trying to do so) while you are taking gabapentin for the treatment of epilepsy, mental illness, or other conditions. A small number of adults and children 5 years of age and older (about 1 in 500 people) who took anticonvulsants such as gabapentin to treat various conditions during clinical studies became suicidal during their treatment. Some of these people developed suicidal thoughts and behavior as early as one week after they started taking the medication. There is a risk that you may experience changes in your mental health if you take an anticonvulsant medication such as gabapentin, but there may also be a risk that you will experience changes in your mental health if your condition is not treated. You and your doctor will decide whether the risks of taking an anticonvulsant medication are greater than the risks of not taking the medication. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: panic attacks; agitation or restlessness; new or worsening irritability, anxiety, or depression; acting on dangerous impulses; difficulty falling or staying asleep; aggressive, angry, or violent behavior; mania (frenzied, abnormally excited mood); talking or thinking about wanting to hurt yourself or end your life; withdrawing from friends and family; preoccupation with death and dying; giving away prized possessions; or any other unusual changes in behavior or mood. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.
