The Mild–and Serious–Side Effects of Gabapentin

For many individuals, gabapentin (also known as Neurontin) is a necessary medication. It can be used to treat seizures, neuropathic pain, restless leg syndrome, and a number of other issues. Unfortunately, though, like most medications, gabapentin has a number of side effects, some of which are mild but many of which can be serious, even dangerous.

Mild Gabapentin Side Effects

The National Library of Medicine states that the drug “may cause side effects” that can be uncomfortable or frustrating to the user. Many of the most common side effects are not dangerous and can be treated by having your doctor reduce your prescription or prescribe another type of medication to minimize them. However, you should always talk to your doctor first when you begin to experience these issues. Never stop taking gabapentin altogether, as the drug can cause a severe withdrawal syndrome.

The mild side effects associated with gabapentin include:

Serious Side Effects of Gabapentin

Gabapentin can cause serious issues as well, some of which are direct effects of the more common side effects associated with normal use of the drug. According to the US Food and Drug Administration, the “sleepiness and dizziness” often caused by normal gabapentin use can “increase the occurrence of accidental injury.” As a patient taking gabapentin, one must remember this possible side effect and be very careful during the times where the drug is active in one’s system.

In addition, gabapentin may cause other serious side effects, including rashes, hives, itching, swelling of the face, throat, tongue, lips, or mouth, hoarseness, or problems swallowing and breathing. If these side effects begin to occur, it is likely that you are allergic to gabapentin. You should seek medical attention right away by calling 911.

As gabapentin is a medication that treats seizures, it can, in very rare cases, cause seizures to occur. For this reason, it is very important that you stay with your correct dosage and you do not take more or less of the drug than you were prescribed or stop taking the medication altogether.

Unpleasant gabapentin side effects children may experience include changes in behavior, memory problems, trouble concentrating, acting aggressively, depression, restlessness, paranoia, and crying.

Some adult users may also experience mood changes, signs of dementia, symptoms of anxiety or depression, feelings of agitation or hostility, restlessness, hyperactivity, and self-harming or suicidal thoughts. If these occur, inform your doctor immediately.
