Dear Jeanne:
I am sorry to hear of your relative. As you probably know already, the quinolones are also a GABA
inhibitorAlpha-glucosidase inhibitors (a neurotransmitter that balances the excitatory stimuli with a negative influence), in addition to it's antibiotic property. The company recommends that this medication not be given to anyone with a pre-existing neurological problem such as seizures. The more
commonCommon cold CNS side effects are headache and restlessness that occurs in approximately 1-2% of those who take the medication. There are some other CNS effects and these are many, but they are rare. These include dizziness, lightheadedness,
insomniaDepression and insomnia
Insomnia concerns
Primary insomnia
Sleeping difficulty, nightmares, hallucinations, lethergy,
drowsinessDrowsiness,
vertigoBenign positional vertigo
Dizziness
Vertigo
Vertigo-associated disorders, nervousness, confusion, manic reactions, toxic psychosis, irritability, weakness, tremor, ataxia, seizures, paresthesia, increased ICP, and depression. Since quinolones are GABA inhibitors they probably should not be taken with other CNS stimulants like large doses of caffeine or theophylline. There have been reported cases of patients resolving into status epilepticus and coma. You can find this information about the above in the packet insert, the PDR, and likely your local pharmacist can give you a copy of the side effect list. I hope this helps.
