From the Guidelines
If you experience blurred vision while taking Macrobid (nitrofurantoin), you should immediately stop taking the medication and contact your healthcare provider as this could be a sign of a serious side effect, such as ethambutol ocular toxicity, which can present with blurred vision, decreased acuity, and impaired color vision, although Macrobid does not contain ethambutol, the concern for vision changes warrants prompt medical attention 1.
Important Considerations
- Blurred vision is not a commonly reported side effect of Macrobid, but it can indicate potential neurological complications or an allergic reaction.
- While waiting to speak with your healthcare provider, avoid driving or operating machinery that requires clear vision.
- Be prepared to tell your doctor when the blurred vision started, if it's constant or intermittent, and any other symptoms you may be experiencing.
- Your doctor may need to switch you to a different antibiotic to treat your infection, as nitrofurantoin can occasionally affect the optic nerve or cause other neurological effects, particularly in patients with kidney problems or those who have been on the medication for a prolonged period 1.
- Never stop an antibiotic without medical guidance, but vision changes warrant prompt medical attention.
Key Points to Discuss with Your Healthcare Provider
- The onset and duration of blurred vision
- Any other symptoms you are experiencing
- Your medical history, including any pre-existing kidney problems
- The potential need to switch to a different antibiotic
- The importance of regular follow-up to monitor for any further complications or side effects 1
