When used with multivitamin or mineral supplements, you may take bictegravir and supplements together at the same time, but with food. Avoid taking bictegravir on an empty stomach simultaneously with, or 2 hours after, dosing of supplements. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed, or if you have trouble separating the dosing times. Your doctor may be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs.
