dextromethorphan is a drug used to treat cough by acting as a cough suppressant. diphenhydramine is an antihistamine and is used to treat allergies.
we'll see if I make it through the night
If you buy anything with "DM" in the name, it probably already had Dextromethorphan in it. So yes, Guafenesin can be taken with Dextromethorphan but taking too much Dextromethorphan can cause a few undesirable side effects. It's unlikely that you'll be able to buy Dextromethorphan by itself anyway, it will likely come with Acetametaphin and Phenylephrine or Guafenesin.
you cannot mix diphenhydramine or acetaminophen with topiramate or topamax. I am unclear why, just that my doctor told me not to do so.
Yes, This is because none of the active ingredients overlap
I'm no doctor, but I have been prescribed these together and had didn't have any adverse reactions.
Diphenhydramine
There is not much of a difference between the two of these. They are diphenhydramine in different salt forms but will have the same effect. Diphenhydramine citrate will be slightly more readily absorbed in the body than HCl.
It is generally not recommended to mix Unisom (which contains diphenhydramine) and clonazepam due to the increased sedative effects and risk of respiratory depression. Always talk to your healthcare provider before combining medications.
The chemical formula for diphenhydramine is C17H21NO
No, you shouldn't mix Benadryl (diphenhydramine) with Neurontin (gabapentin) unless your vet has said it's okay, and has told you the correct dose of medications. Taken together, they can effect the central nervous system of your dog and possibly also depress the respiratory system.
The chemical formula for Dextromethorphan Hydrobromide (HBr) is C18H25NOยทHBr.
