Gabapentin vs. Tramadol

• Gabapentin and tramadol are used to treat different types of pain.
• Gabapentin is an anti-seizure (anticonvulsant) medication used to prevent seizures and to treat post-herpetic neuralgia, the pain that follows an episode of shingles.
• Tramadol is an opioid pain reliever (analgesic) used to manage moderate to moderately severe pain.
• Brand names for gabapentin include Neurontin, Horizant, and Gralise.
• Brand names for tramadol include Ultram and ConZip.
• Side effects of gabapentin and tramadol that are similar include nausea, vomiting, dizziness, or drowsiness.
• Side effects of gabapentin that are different from tramadol include sleepiness, loss of control of bodily movements, fatigue, fluid retention (edema), hostility, difficulty speaking, jerky movements, unusual eye movements, double vision, tremors, memory loss, unsteadiness, weight gain, joint pain, motion sickness, blurred vision, or viral infection.
• Side effects of tramadol that are different from gabapentin include constipation, headache, euphoria, indigestion, spasticity, and weakness.
• As with other narcotics, withdrawal symptoms may occur if you suddenly stop taking tramadol.

• Gabapentin is an anti-seizure (anticonvulsant) drug that is used for preventing seizures and for treating post-herpetic neuralgia, the pain that follows an episode of shingles. Other off-label uses for gabapentin include anxiety, alcohol withdrawal, cocaine withdrawal, hiccups, restless leg syndrome, hyperhidrosis, headaches, diabetic neuropathy, hot flashes, and fibromyalgia.
• Tramadol is an opioid pain reliever (analgesic) used to manage moderate to moderately severe pain. The exact mechanism of action of tramadol is unknown, but it is similar to morphine. Like other narcotics used to treat pain, patients taking tramadol may abuse the drug and become addicted to it. Tramadol is not a nonsteroidal anti-inflammatory drug (NSAID) and it does not have the increased risk of stomach ulcers and internal bleeding that can occur with NSAIDs.

Some patients who received tramadol have reported seizures. It may cause serotonin syndrome when combined with other drugs that also increase serotonin (see drug interactions section).

Tramadol is a narcotic and is addictive. Tramadol is a Schedule IV controlled substance that has been associated with addiction, abuse, and misuse. Tramadol may be addictive, even at the dosage your doctor has prescribed. Abuse or misuse of tramadol can lead to overdose and death.

Like other opioids, people who take tramadol for a long time will develop withdrawal symptoms if your doctor reduces the dosage, or if you suddenly stop taking tramadol.

Gabapentin dosage

Gabapentin is available as:

• Capsules: 100, 300, and 400 mg.
• Tablets: 100, 300, 400, 600, and 800 mg.
• Solution: 250 mg/5 ml

Tramadol dosage

• The recommended dose of tramadol is 50-100 mg (immediate release tablets) every 4-6 hours as needed for pain.
• The maximum dose is 400 mg/day.
• To improve tolerance patients should be started at 25 mg/day, and doses may be increased by 25-50 mg every 3 days to reach 50-100 mg/day every 4 to 6 hours.
• The recommended dose for extended release tablets is 100 mg daily, which may be increased by 100 mg every 5 days, but not to exceed 300 mg /day. To convert from immediate release to extended release, the total daily dose should be rounded down to the nearest 100 mg. Extended release tablets should be swallowed whole and not crushed or chewed.
• Tramadol may be taken with or without food.

Gabapentin drug interactions

Antacids reduce the concentration of gabapentin in blood. Therefore, gabapentin should be administered 2 hours or more after taking antacids. Morphine significantly increases blood concentrations of gabapentin and may increase central nervous system-related adverse events associated with gabapentin.

Tramadol drug interactions

• Carbamazepine (Tegretol, Tegretol XR, Equetro, Carbatrol) reduces the effect of tramadol by increasing its inactivation in the body.
• Quinidine (Quinaglute, Quinidex) reduces the inactivation of tramadol, thereby increasing the concentration of tramadol by 50% to 60%.
• Combining tramadol with monoamine oxidase inhibitors or MAOIs (for example, tranylcypromine [Parnate]) or selective serotonin inhibitors (SSRIs), for example, fluoxetine (Prozac), may result in severe side effects such as seizures or a condition called serotonin syndrome.
• Tramadol may increase central nervous system and respiratory depression when combined with alcohol, anesthetics, narcotics, tranquilizers, or sedative hypnotics. This can reduce the level of consciousness or lead to respiratory insufficiency.

Gabapentin

• Doctors do not know the safety of gabapentin during pregnancy. Gabapentin is secreted in human breast milk; therefore, if you are pregnant you should only use this medication if the benefits outweigh the unknown risk to the fetus.

Tramadol

• Researchers have not established the safety of tramadol during pregnancy, The safety of tramadol during pregnancy has not been established. Mothers who are breastfeeding should not take tramadol because the infant may develop side effects, and will develop symptoms of withdrawal and difficulty breathing.
