While taking hydroxychloroquine (Plaquenil), avoid exceeding your prescribed dose and do not combine it with other medications or supplements without checking with your healthcare provider first. Hydroxychloroquine can cause drug interactions with certain medications, including some heart medications, antacids, diabetes treatments, and seizure medications.
Alcohol can worsen certain side effects, such as stomach upset, dizziness, or headaches. For people taking hydroxychloroquine to manage autoimmune conditions, alcohol may contribute to fatigue or inflammation, which can interfere with symptom control.
