Hi. Thanks for posting your query here. Conjunctivitis may be bacterial or viral in majority of the affected patients. Logically, antibacterials would work on the bacterial form of conjunctivitis. You have been using a number of medications but I do not believe you have completed the course of any of them to appreciate a significant improvement. It has been close to a month since you first experienced symptoms so I recommend a mild antibiotic and steroid combination eyedrop for a period of 5 days with a frequency of 3 times a day. Use lubricating eye drops and rest assured they do not have any significant side effects to be concerned about especially if you use preservative free medication like Refresh tears 4 times a day. Use a lubricating eye ointment at bedtime as well. Approximately 5 to 7 days later, your symptoms should subside and you may resume use of contact lenses. If you did indeed have conjunctivitis and were using the pair of lenses you have currently, you will have to consider replacing the pair with a fresh pair of lenses.
