From the Guidelines
If you experience headaches while taking Macrobid (nitrofurantoin), contact your healthcare provider to discuss your symptoms, but don't stop taking the medication without medical advice. Headaches are a known side effect of Macrobid that typically resolve on their own. While waiting to speak with your doctor, you can try taking the medication with food to reduce side effects, stay well-hydrated, and use over-the-counter pain relievers like acetaminophen if approved by your provider, as suggested by the American College of Physicians in their clinical guideline for pharmacologic treatments of acute episodic migraine headache in outpatient settings 1. Some key considerations for managing headaches include:
- Treating mild episodic migraine headache with an NSAID, acetaminophen, or the combination of an NSAID and acetaminophen 1
- Considering the use of CGRP antagonists-gepants or ergot alkaloid for moderate to severe acute episodic migraine headache in nonpregnant outpatient adults who do not tolerate or have inadequate response to combination therapy of a triptan and an NSAID or acetaminophen 1
- Avoiding the use of opioids or butalbital for the treatment of acute episodic migraine 1 If your headaches are severe, persistent, or accompanied by other concerning symptoms such as visual disturbances, confusion, or neck stiffness, seek immediate medical attention as this could indicate a more serious reaction. Headaches may occur because nitrofurantoin affects certain metabolic processes in the body, but most side effects are temporary and diminish as your body adjusts to the medication. Remember that Macrobid is prescribed to treat urinary tract infections, and completing the full course is important to properly clear the infection. It's also important to note that lifestyle modifications, such as staying well hydrated, maintaining regular meals, securing sufficient and consistent sleep, engaging in regular physical activity, managing stress, and pursuing weight loss if applicable, can help manage migraine headaches, as highlighted in the clinical guideline 1.
