Frequently asked questions
- How is Redisol rated?
- pharmaranks gives Redisol a composite score of 3.6 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 Redisol 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 $1.49 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 Redisol?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Redisol. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.

What people report to the FDA about CYANOCOBALAMIN
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 41,533 reports naming CYANOCOBALAMIN — the active ingredient in Redisol, and the FDA flagged 75% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- fatigue4,046 reports
- nausea3,323 reports
- headache2,814 reports
- diarrhoea2,789 reports
- dyspnoea2,546 reports
- vomiting2,229 reports
- asthenia2,135 reports
- arthralgia2,102 reports
Read these as a signal, not a rate. A report does not mean CYANOCOBALAMIN caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.
