DXM plateaus
    #9165187 - 10/31/08 05:55 PM (12 years, 4 months ago)

Got a question.

I want to trip on DXM today and I'd like to get to either the 3rd or fourth plateaus... I need 750-1250 or some shit. How much DXM is in a bottle of robitussin?

I usually down a bottle of 'tussin and just have an OK time, but I'm not that messed up.

How many bottles would 750-1250 be? This isn't a dosage question, just want to know how many mgs is in 750-1250 or whatever it is for 3rd plateau.

1250 mgs of DXM would be a borderline insane dose

Robo is usually 15mg/tsp.. a 4oz has 354 mgs, 8oz 708mg.

have fun

^You cannot determine the strength of a dose based on milligrams alone. DXM is dosed in mg/kg.

It depends.  This is pretty easy math.  Look on the side of the bottle, where it says "active ingredients."  Most max. strength cough syrups will be Dextromethorphan HBr 3 mg/mL which means that there are 3 mg of DXM HBr per mL of syrup.

Total dose in bottle:
concentration * total volume

so, a 4 oz bottle is approx. 120 mL
3 mg/mL * 120 mL = 460 mg.

Honestly, if you can't figure out how to multiply, then you shouldn't be trying to figure out doses.

As for the plateaus, the FAQ gives a pretty good guideline, but remember that these are not hard and fast rules.  I usually like 10 mg/kg, which means 10 mg of DXM HBr per kg of bodyweight.  So, take your bodyweight in kg, and multiply by ten.

Suppose you weigh 70 kg.  70 kg * 10 mg/kg = 700 mg.
How much syrup do you need?
700 mg / (3 mg/mL) = approx. 233 mL.

Please, learn how to multiply and divide first.

Robitussin Long-Acting (or "max strength") has 354mg of DXM in it.

Robitussin Cough Gels have 300mg of DXM per bottle, or 15mg per gel.



Hope that helps. Be safe, and enjoy.
