How to use Nor-TZ Tablet

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Nor-TZ Tablet should be taken with or after food.

How Nor-TZ Tablet works

Nor-TZ Tablet is a combination of two antibiotics: Norfloxacin and Tinidazole. Norfloxacin works by preventing the bacterial cells from dividing and repairing, thereby killing the bacteria. Tinidazole kills parasites and anaerobic bacteria that cause infections by damaging their DNA. Together, they treat your infection effectively.

Quick tips

  • Diarrhea can cause dehydration. Drink plenty of fluids to keep yourself hydrated. Consult your doctor if your diarrhea lasts for more than 48 hours.
  • It may cause dizziness and sleepiness. Do not drive or perform any activity that requires mental focus until you know how it affects you.
  • Do not take this medicine with milk or any other dairy product, as they contain calcium, which can bind to one of its ingredients and prevent it from working properly.
  • To ensure proper absorption, avoid taking antacids, iron supplements, calcium supplements, or multivitamins 2 hours before or after your dose.
  • Notify your doctor if you experience pain in your tendons, numbness, or tingling sensations.
  • Inform your doctor if you are pregnant, planning to conceive, or breastfeeding.
  • In diabetic patients, it may cause unexpected hypoglycemia (low blood sugar). Checking your blood glucose levels more frequently while taking Nor-TZ Tablet is recommended.

Frequently asked questions

Nor-TZ Tablet is a combination of two medicines: norfloxacin and tinidazole. This medication is used to treat diarrhea and dysentery. It works by killing harmful microorganisms responsible for the infection. Together, they help treat the infection more effectively.
No. Do not stop taking Nor-TZ Tablet. Complete the full course of treatment even if you feel better. Your symptoms may improve before the infection is completely cured.
Yes, Nor-TZ Tablet is known to increase the risk of tendon rupture, most commonly affecting the Achilles tendon. Tendon problems can occur in people of all ages who take Nor-TZ Tablet, but the risk is higher in older adults, people taking steroids, or those with kidney disease. Inform your healthcare provider immediately if you hear or feel a snap or pop, experience severe pain, notice rapid or immediate bruising after an injury, or are unable to use the affected arm or leg. These symptoms may indicate a tendon rupture.
Yes, it can cause a temporary metallic taste. Chewing sugar-free gum or mints, brushing your teeth after meals, and staying well hydrated may help.
Nor-TZ Tablet should not be used in patients with a known allergy to norfloxacin, tinidazole, or any other excipient in the formulation. It should preferably be avoided in patients with a history of tendinitis or tendon rupture related to ciprofloxacin or other quinolone antibiotics. It is also generally avoided in patients with certain neurological disorders (such as a history of seizures).
No. Avoid drinking alcohol while taking Nor-TZ Tablet and for at least 3 days after completing the course. Consuming alcohol may cause a disulfiram-like reaction, with symptoms such as stomach pain, nausea, vomiting, headache, flushing, or redness of the face.
Yes, you can take ORS (oral rehydration salts) with Nor-TZ Tablet. ORS is a special combination of salts mixed with clean drinking water that helps restore fluids lost due to diarrhea.
No. Taking more than the recommended dose of Nor-TZ Tablet can increase the risk of side effects. The medicine takes time to fully take effect and treat the infection. If your diarrhea worsens or does not improve with the recommended dose, consult your doctor for re-evaluation.
Avoid taking antacids containing magnesium or aluminum at the same time as Nor-TZ Tablet. These minerals can bind to the antibiotic, reducing its absorption and potentially decreasing its effectiveness. Your doctor will usually advise taking antacids at least 2 hours before or after your antibiotic dose.
Nor-TZ Tablet is primarily eliminated through the kidneys. It is generally safe in people with normal kidney function. However, in elderly patients or those with known kidney impairment, the doctor may need to carefully adjust the dose. Staying well hydrated by drinking plenty of water while taking this medication is important.
Most patients begin to notice improvement in stomach symptoms within 24 to 48 hours of starting Nor-TZ Tablet. However, even if you feel better quickly, the infection may not be completely cleared. You must complete the entire prescribed course to prevent recurrence or antibiotic resistance.
