Frequently asked questions

What if I cannot tolerate Alerta Injection?

It is common to have minor side effects such as nausea, vomiting, diarrhea and headache but generally these settle down. If these symptoms trouble you, contact your doctor. Your doctor may prescribe an alternative medicine to help you get rid of these symptoms. Serious side effects occur in very rare cases. But, if you experience any serious complication, seek immediate medical advice.

What is drug resistance? Is it possible to develop resistance to Alerta Injection?

Drug resistance is a condition in which the bacteria gets modified in your body and stops reacting to the medicine. Because of this, the medicine stops working. Resistance to Alerta Injection is not very common at least for the bacteria against which it works.

Does Alerta Injection have any effect on blood sugar levels if taken to treat infections of diabetic foot?

Rare reports suggest that Alerta Injection may decrease the blood sugar levels, but this medicine does not affect the blood sugar levels in everyone. However, it is important to keep monitoring your blood sugar levels regularly. Consult your doctor if you experience any sudden dip in blood sugar levels.

Is Alerta Injection safe to be used in children?

Safety of Alerta Injection in children less than 3 months of age has not yet been assessed. However, the side effects and effectivity of Alerta Injection in children beyond the age of 3 months is almost similar when compared with adults.

I feel better now. Can I stop taking Alerta Injection?

No. Make sure to receive all doses your doctor has prescribed, even if you feel better. This is because your symptoms may have improved but chances are that the infection is still present in your body. Skipping doses can increase the risk of developing an infection that is resistant to medication. So, continue taking Alerta Injection as prescribed. After you have finished all the doses, your doctor may advise you on some tests to make sure your infection has completely cleared up.
