You may need to eliminate grapefruit products from your diet because simply taking your medication and grapefruit product at different times doesn’t stop the interaction.
Alternatively, you can ask your health care provider if there’s a comparable medication you can take that doesn’t interact with grapefruit.
Never take or stop taking a med without a go ahead from your healthcare provider or pharmacist. Be safe!
