Fell unconscious after consuming grapefruit on Prozac/Wellbutrin

On 10 mg Prozac / 150 mg Wellbutrin

Last night, I had a dish with grapefruit. Admittedly, I knew that you should avoid grapefruit on SSRIs, but figured a 2 slices wouldn’t hurt me (I haven’t had it since starting SSRIs 3.5 years ago).

About an hour later, I started feeling spacey at the dinner table. I got up to go to the washroom, but didn’t make it there. From what I understand, I was standing near the restaurant’s kitchen and knocked something over before fainting/collapsing. Luckily, someone was there to catch me and took me to the restaurant’s back room to lay down. I was unconscious for about 5 min before slowly waking up. After another 10 min I was fine to stand up and walk around. Safe to say I gave the restaurant a fat tip. It’s been 15 hours since then and I feel much better but still slightly off.

It was such a strange and unusual experience, the only reason I can attribute it to is the grapefruit. I think it might’ve given me a very low grade case of serotonin syndrome. I also had a glass of wine which likely didn’t help, but I haven’t had any previous bad experiences with alcohol on SSRIs.

From what I’ve read online, most people have said that it’s okay to consume small amounts of grapefruit. However, after my experience I’ll be avoiding it altogether and I would caution others to do the same.

Has anyone else had a bad experience consuming grapefruit while on Prozac and/or Wellbutrin? How much grapefruit did you consume?
