nalidixic acid-oral (cont.)
PRECAUTIONS: Tell your doctor if you have: kidney problems, liver disease, seizure disorder, nervous system disorder, blood vessel disease, any allergies. Use caution driving or performing tasks requiring alertness if this medication makes you drowsy, dizzy, or lightheaded. Limit alcohol intake. Because this medication may make you more sensitive to the sun, avoid prolonged sun exposure. Wear protective clothing and use a sunscreen when outdoors. Tell your doctor if you are pregnant before using this drug. This drug is excreted into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Tell your doctor of all the medications you may use, both prescription and nonprescription, especially of: warfarin, certain live vaccines, nitrofurantoin, quinapril, didanosine, vitamins/minerals (e.g., magnesium, aluminum, calcium, iron, zinc), antacids, sucralfate, bismuth subsalicylate. Do not start or stop any medicine without doctor or pharmacist approval.
OVERDOSE: If overdose is suspected, contact your local poison control center or emergency room immediately. US residents can call the US national poison hotline at 1-800-222-1222. Canadian residents should call their local poison control center directly. Symptoms of overdose may include seizures, vomiting, nausea, and unusual sluggishness.
NOTES: This medication has been prescribed for your current condition only. Do not use it later for another infection or give it to someone else. A different medication may be needed in those cases. Nalidixic acid can cause false results in some diabetic urine testing products (cupric sulfate-type). Consult your doctor or pharmacist for recommendations.
MISSED DOSE: If you miss a dose, take as soon as remembered; do not take if it is almost time for the next dose, instead, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up.
STORAGE: Store at room temperature away from sunlight and moisture. If your doctor tells you to stop taking nalidixic acid, throw away any unused medication. Nalidixic acid loses effectiveness over time and should not be saved to treat another infection.
