2.1. Amebiasis
Ornidazole tablets are used to cure amebiasis. This is an intestinal infection caused by Entamoeba histolytica.

- Pre-existing conditions;
- Allergies;
- Age and weight, etc.

6. Usage Safety Advices
By following these recommendations, you will prevent the majority of side effects and other problems connected with antibiotic treatment.
6.1. Pregnancy
The use of Ornidazole for pregnant women isn’t recommended. Your doctor may prescribe it only if the benefits of the drug are more valuable than the potential risk for the mother-to-be and the fetus.
There’s little information about the harmful effects of the medication on humans. However, animal studies have shown danger for the baby. Always consult a doctor before taking any antibiotics.
6.2. Breast-feeding
Consult your doctor if you want to take Ornidazole to treat a bacterial infection. There’s no information on whether the drug passes through the milk to the baby. But precautions need to be taken to make sure both the mother and the child are safe.
6.3. Renal/Hepatic Impairment
It’s safe to take Ornidazole if you have a renal or hepatic impairment, but only if your doctor knows about the condition and still prescribes the drug. A dose adjustment may be necessary for such patients, but this isn’t guaranteed. Your doctor should be able to prescribe sufficient dosage for your quick recovery without severe side effects.
If you have a hepatic impairment, the dose adjustment may be different if needed because the drugs are processed by the liver as well. To avoid buildup and other issues during the treatment course, always talk to your doctor about pre-existing conditions you have.
6.4. Epilepsy
It’s possible to use Ornidazole as a treatment in patients with epilepsy, but only if the doctor prescribes it. Side effects of the drug include seizures, which is a red flag for people with epilepsy.
Another precaution is driving or using any kind of machinery. The medicine may cause dizziness and poor coordination, so you don’t want to drive or operate appliances during the course of treatment.
7. What Can I Take Instead of Ornidazole
Metronidazole is a similar antibiotic, which is also used in the treatment of protozoal diseases. Most medical specialists vote in favor of Ornidazole, though, due to its advantages. First of all, it has a longer half-life. The side effect list is also shorter, which opens more possibilities for treatment and dosage.
This study is a great example, proving that the two medications are interchangeable. However, it’s strictly not recommended to change your treatment without consulting a doctor first.
Don’t try to prescribe antibiotics yourself if you don’t have a medical license. A professional should study your symptoms and medical history before creating a treatment complex that will cure the condition safely and effectively.
