methocarbamol and aspirin

How long does Aspirin and Methocarbamol stay in your body?

The elimination half-life of aspirin and methocarbamol is about 1 to 2 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. The FDA label reports a mean plasma elimination half-life of 1 to 2 hours in healthy volunteers (about 1.1 hours in a younger group). It names no active metabolite: methocarbamol is cleared by dealkylation, hydroxylation and likely conjugation, and essentially all metabolites leave in the urine, with the label describing no lingering active one. Older adults clear it only slightly more slowly (mean 1.5 hours at a mean age of 69, vs 1.1 hours in a younger group). Kidney impairment barely changes the half-life — in 8 hemodialysis patients it was 1.2 hours vs 1.1 hours in normal subjects — even though total clearance fell about 40%. Liver disease matters most: in 8 patients with alcohol-related cirrhosis, total clearance dropped roughly 70% and the mean half-life rose to about 3.4 hours. Protein binding is 46-50% normally and drops to roughly 40-45% in cirrhosis and 41-43% in older adults. These figures come from immediate-release oral tablets and the IM/IV injection; the label covers no extended-release methocarbamol form.

It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.

Frequently asked questions

How much does Methocarbamol and Aspirin cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.78 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
