Hello, I have been suffering from objective vertigo and as such have been told to take Betahistine 16MG 3 times daily. I had almost forgotten to take it this afternoon and took it later than usual because of that. It is now time for me to take my 3rd dosage today and my second was taken only 3 hours ago. Would it be okay for me to take my 3rd dosage now? Or should I skip the dosage?
