How long does Phenylephrine Hydrochloride and Promethazine Hydrochloride stay in your body?

The elimination half-life of phenylephrine hydrochloride and promethazine hydrochloride is about 9 to 16 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. Kinetics are linear (no saturable/dose-dependent behavior). The FDA label reports a plasma half-life of 9-16 hours after IV dosing and a mean of 9.8 ± 3.4 hours after IM dosing; the oral tablet label omits a numeric half-life but describes the same disposition. Duration of clinical effect (about 4-6 hours, occasionally up to 12) is shorter than the elimination half-life, so sedation can wear off well before the drug clears. Promethazine is metabolized in the liver to sulfoxides of promethazine and N-desmethylpromethazine (the main urinary metabolites); the label does not characterize these as clinically active or as outlasting the parent. Not a prodrug. Because clearance is hepatic, impaired liver function may prolong the half-life; the label gives no specific age- or kidney-based half-life values.

Frequently asked questions

How is Phenergan Vc rated?

pharmaranks gives Phenergan Vc a composite score of 3.5 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.

How much does Phenergan Vc 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 $8.59 per ml, 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.

Is there a coupon or discount for Phenergan Vc?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Phenergan Vc.
