Blurred eyes after taking anti-tuberculosis drugs may be caused by the side effects of anti-tuberculosis drugs. Oral medications that nourish the optic nerve, such as methylcobalamin, etc., should be taken under the guidance of a professional doctor, and dexamethasone eye drops can also be used as prescribed by the doctor to improve the symptoms of blurred eyes. During the period of anti-tuberculosis treatment, blurred eyes may be a side effect of taking anti-tuberculosis drugs, such as ethambutol hydrochloride tablets, propylthioisonicotinamide tablets and so on. If the eyes are blurred after taking anti-tuberculosis drugs, oral methylcobalamin tablets can be taken under professional doctor’s guidance, which can protect the optic nerve, and dexamethasone eye drops can also be used as prescribed by the doctor to improve the symptoms of blurred eyes. If the symptoms of blurred eyes are not relieved after taking the medication, the use of the above mentioned anti-tuberculosis medication should be suspended and changed to other medications with less side effects, such as combining the application of amikacin and levofloxacin for anti-tuberculosis treatment in conjunction with a professional doctor’s treatment advice. If you have blurred eyes after taking anti-tuberculosis drugs, it is recommended that you give feedback to your treating doctor as soon as possible, so that you can adjust your treatment plan in time to relieve the symptoms of blurred eyes.
