Diet & Lifestyle Advise

  • Avoid consuming excessive amounts of caffeine-containing foods and beverages such as coffee, tea, cola, energy drinks, and chocolate.
  • Probiotics should be taken after finishing the entire course of OMNATAX 500MG INJECTION to replenish good bacteria. The risk of antibiotic-associated diarrhoea can be decreased by taking probiotics after receiving antibiotic treatment. Some fermented foods, including yoghurt, cheese, sauerkraut, and kimchi, can help rebuild the beneficial bacteria in the intestine. 
  • Increase your intake of fibre-rich foods since they are simpler for gut bacteria to digest, encouraging their growth.
  • While taking OMNATAX 500MG INJECTION, make sure to drink lots of water or other fluids.
  • Avoid drinking alcohol since it may cause dehydration and interfere with your sleep, which makes it difficult for your body to help OMNATAX 500MG INJECTION fight infections.

Inform the doctor if you do not feel better after completing the whole course of treatment. You must also notify your doctor if your symptoms worsen while using this medication.

OMNATAX 500MG INJECTION is an antibiotic used to treat bacterial infections only. OMNATAX 500MG INJECTION does not treat a viral infection like the flu or a common cold.

You are recommended to take OMNATAX 500MG INJECTION for as long as it is advised by your doctor for effective results. If your symptoms continue or worsen, seek further advice from your doctor.

Inappropriate use of antibiotics means using them when they are not necessary, such as for viral infections (like colds or the flu), stopping the treatment early, or using the wrong antibiotic for a specific infection. This can lead to antibiotic resistance.

Antibiotic resistance occurs when bacteria change in a way that reduces the effectiveness of antibiotics. As a result, the drugs no longer kill the bacteria, making infections more difficult to treat. This resistance can develop from overusing or misusing antibiotics, like taking them unnecessarily or not finishing the prescribed course.

No, OMNATAX 500MG INJECTION is not the same as penicillin. OMNATAX 500MG INJECTION contains ceftriaxone, a cephalosporin antibiotic, while penicillin belongs to a different class of antibiotics. Both treat bacterial infections, but they work in different ways.

These do not require any medical treatment as they will gradually reduce over time. However, please contact a doctor if these side effects persist or worsen.
