any people who know anything about medicines, and doses??

I suffer from severe OCD which comes along with a fear of vomitting. As a result, my psychiatrist perscribed me the anti-nasuea medicine Compazine to just take if I feel the onset of a stomach ache. This morning I woke with a stomach ache and diarhea, so for percaustion i took the 25 MG suppository. My problem is it says only take it twice a day. I was unaware of that because i have the pill form as well which is supposed to be taken 3 times a day, so I took the next dose 8 hours after the first instead of 12. Im worried i will get sick if i dont take another dose, so im wondering if i can take the pill which is 10 MG.

When i researched online it said to take 2 doses of the suppository (50 MG)
but the pill for says max (40mg)

im confused on whether or not i can take the pill, or if it could casue me harm.
In addition, the pill can also be taken for schizophrenia, and you can take up to 175 MG for that, does that mean it cannot harm me to take 60 mg?will it ust make me drowsy?
i am currently NOT on any other medications for my OCD...thanks so much for your contributions!
I also only take these pills the day i feel sick, which has been since last year. I also dont plan on taking it again tomorrow so i would be on it long term. Just 24 hours.
