Vidarabine eye ointment is used to treat viral infections of the cornea, especially those caused by the herpes simplex virus. It works by stopping the virus from multiplying inside the eye cells, which contributes to relieving symptoms such as redness, pain, and itching, and promotes the rapid healing of infected tissues. The ointment must be applied carefully according to the doctor's instructions. Wash your hands well before use and avoid touching the tip of the tube to any surface or directly to the eye to maintain the cleanliness of the ointment. It is not recommended to wear contact lenses during the treatment period. You should also consult your doctor if you experience unusual symptoms such as persistent irritation or severe allergic reactions. Vidarabine eye ointment is an important treatment for controlling viral corneal infections.
