Product introduction

Tobcon 0.3% Eye Drop stops the growth of bacteria and thereby helps to cure the underlying infection. Follow your doctor's instructions precisely for administering this medicine. Wait for at least 5 minutes before applying any other eye medication. It should be used regularly at evenly spaced time intervals as prescribed by your doctor. Do not skip any doses and finish the full course of treatment even if you feel better. Stopping the medicine too early may lead to the infection returning or worsening.

Common side effects seen with this medicine include temporary eye irritation, burning sensation, itching, and redness after administration. Consult your doctor if these side effects persist or if your condition worsens. It may cause some short-term blurring of vision when first used. Therefore, do not drive immediately after administering this medicine. Contact lenses should not be worn while you are using this medicine or while you have an active eye infection.

Tobcon 0.3% Eye Drop will not work for eye infections that are not caused by bacteria (e.g., viral) and therefore, should only be used if prescribed by your doctor. Unnecessary use of any antibiotic can lead to a decrease in its effectiveness in the future.
