We found no known interaction between Guaiac Wood and methylphenidate transdermal system in our sources.

Guaiac Wood and methylphenidate transdermal system
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between methylphenidate transdermal system and Guaiac Wood in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the methylphenidate transdermal system page
“Daytrana, the methylphenidate skin patch for ADHD, is itself a stimulant, and that shapes nearly this whole list, which I read as one that calls for real care. Of the 68 supplement ingredients on file, 44 are stimulants too, so pairing them can push heart rate and blood pressure higher than either alone.”
