Yes, your vibrator or other toys are safe with estrogen creams, often prescribed for vaginal dryness.
What you’ll want to be careful of is silicone-based lubricants. Whether they’re safe to use with your vibrator depends on the materials used; silicone lubes will ruin the surface of a silicone toy. The instructions that came with your vibrator (or are available online) will usually tell you what’s safe and what’s not.
I’ve seen patients have good results with estrogen cream; hope you have the same!
