Can I Exceed The Dosage Of Gravol As I Can T Bear The Vomiting?

I m throwing up, diarrhea sick. I haven t eaten in 24 hours because I won t be able to keep it down. I can t drink either, only when I m taking pills. The only thing stopping me from throwing up again is gravol (dimenhydrinate). I have just the last 2 pills of my daily dosage which is 400mg. The 24 hours isn t up until 10am tomorrow and I know I won t be able to sleep if I m throwing up, I haven t slept well in a couple days so I really need it! And I have a fear of throwing up so I really don t want to throw up again. Am I aloud to exceed my daily dosage under these circumstance? Please get back to me with in the next 4 hours so I will know if it is alright to take more or not. Thank you in advance!

HI, thanks for using healthcare magic

It would be best not to exceed the maximum dose of any medication because of increased risk of associated side effects but you can try a medication from another family to work with eg peptobismol, this is also over the counter.

Persistent vomiting is often related to the acid content in the blood. This can be reduced by using very small amounts of fluids.
If you use a large amount, you would vomit.

Obtain an oral rehydration drink or sports drink. Use approximately 1 tsp or 1 tbs every 5 minutes for an hour.
If this is tolerated you can increase the amount and the frequency slightly for the next hour. This in itself would help reduce the acid and the vomiting.

You may also want to use probiotics as well, this would help to shorten the course of diarrhea. They can be used either on their own or with yogurts.
The pepto bismol would also help with the diarrhea.

I hope this helps
