Seizures, which are characterized by involuntary physical movement, can have a variety of causes. One of the most common causes of seizures is epilepsy, or a pattern of recurring seizures. However, certain medications may also induce seizures.

Causes

According to Epilepsy.com, while there are many medications that may cause seizures, few consistently cause seizures in all patients. Elements such as dosage, interaction with other drugs and tolerance levels affect whether or not a medication may cause a seizure. If you have a history of seizures, it is recommended that you discuss all medications and supplements with your physician prior to use.

Antibiotics

Some antibiotics that have been found to cause seizures include amphotericin B, ciprofloxacin, levofloxacin and metronidazole.

Attention Deficit Disorder

Medications sometimes prescribed for attention deficit disorder (ADD) that may be linked to seizures include dextroamphetamine and methylphenidate.

Drug Toxicity

Some people have a seizure as a reaction to local anesthetics, according to the journal Anesthesia & Analgesia. Another example of a drug that may cause seizures is aminophylline, which is prescribed for asthma and other lung diseases.

Tricyclic Antidepressants

Examples of some tricyclic antidepressants are clomipramine and amitriptyline. According to the U.S. Department of Veterans Affairs, some tricyclic antidepressants, clomipramine in particular, carry with them a higher risk of seizure activity.

Others

According to Merck, other prescription drugs that may cause seizures include the following: buspirone (used to treat anxiety disorders), ceftazidime (an antibiotic), chlorpromazine (used to treat schizophrenia), ciprofloxacin (an antibiotic), chloroquine (used to treat malaria), indomethacin (used to relieve pain and reduce inflammation), and meperidine (used to relieve pain).
