Cautions with other medicines
Hydroxychloroquine can affect the way some medicines work. Other medicines can also affect the way hydroxychloroquine works or increase the chance of you getting side effects.
If you take antacids, leave a gap of at least 4 hours between taking them and hydroxychloroquine.
Tell your doctor or pharmacist if you're taking any other medicines, including:
- azithromycin, erythromycin or clarithromycin, antibiotics
- amiodarone or digoxin, medicines for heart problems
- medicines for epilepsy
- medicines for diabetes, such as insulin or metformin
- cimetidine, a medicine for stomach ulcers
Mixing hydroxychloroquine with herbal remedies and supplements
There's not enough information to say that herbal remedies and supplements are safe to take with hydroxychloroquine. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
