Do I have to abstain from drinking for a period before I start?

No, you begin treatment right away.

What's it like to drink on the medication?

Reports vary but most won't notice much of a difference when drinking with naltrexone in their system.

Once I get my stuff under control do I have to keep taking the medication?

Only when you drink. By always following the dosing protocol relapse is avoided.

Do I have to request refills of the medication?

Yes, reach out to your Alcure provider when you're down to about 10 days' worth of naltrexone to allow lead time. Sometimes your provider may refill a greater number of tablets over prior prescriptions depending upon your progress and overall situation. Always reach out well in advance before you're completely out, though.

What happens when I only need a maintenance supply of the medication?

When to switch to maintenance use of naltrexone is a decision for you and your Alcure medical provider. Maintenance use involves periodic reassessment by your Alcure provider before receiving a new e-prescription and will vary with each client. Once you reach maintenance, you'll cancel recurring payments and schedule occasional one-time visits with your Alcure provider as-needed. The cost of a one-time visit is equal to one monthly payment. Reach us at support@alcure.me when you and your Alcure provider are ready to make the switch to maintenance use of naltrexone.

Am I locked into a subscription?

No, you may cancel recurring payments at any time and are only responsible for the month in which you cancel. Contact support@alcure.me.

Can I get reimbursed from my medical insurance?

Yes. We provide you a "superbill" each month if you elect to use insurance. A superbill is a detailed receipt identifying the billing codes used by insurance companies to process payments for the type of treatment we provide. We cannot guarantee reimbursement and you may wish to consult your insurance company first for eligibility. Ask us for an example superbill to run by your insurance company in advance.

Can I get reimbursed from my employer?

Many employers have an Employee Assistance Program that will provide employees facing alcohol use disorder with treatment at no cost. And, in many states, depending on the size of your company, employers are legally bound to offer treatment for alcohol use disorder if an employee requests it. If you are employed and experiencing an excess drinking issue, tell your employer that you're interested in the Alcure program and ask your employer about how its Employee Assistance Program can be used to cover the cost of our program.

Will anyone find out about my program enrollment or use of naltrexone, such as an insurance company?

Alcure doesn't report any patient's enrollment to anyone unless requested to by the patient or if legally required. On occasion the pharmacy filling a prescription from one of our providers for naltrexone may report the prescription to one or more central computer databases, though, and unfortunately that's not something over which we have control. It doesn't usually happen, but if you have any concerns we recommend you contact the pharmacy you plan to use in advance and ask the pharmacist in charge whether it would report a prescription for naltrexone.

What if I have a surgery or procedure coming up and I'm taking the medication?

Often a doctor performing a surgery or procedure will anticipate using an opioid-based pain medication to alleviate any pain associated with the surgery or procedure. Opioid-based medications will not work if you have naltrexone in your system.

Your doctor may recommend avoiding naltrexone for three days before the surgery or procedure, with the expectation the naltrexone will be eliminated from your system by the third day and the doctor will then feel comfortable using an opioid-based medication if he or she elects to do so.

Patients facing surgeries or procedures should advise their doctor of the last time naltrexone was taken, as that can influence the choice of opioid-based pain medication the doctor may use.

Be sure to advise your doctor well in advance of your naltrexone use so he or she can be equipped with all relevant information to best manage any pain safely as it pertains to your specific health history and the surgery or procedure you're facing.

Are there side effects to the medication?

The vast majority of patients will not experience any side effects from the medication, some will experience mild to moderate side effects that usually go away after a short period, and a few will experience more adverse side effects. Our providers assist each patient as-needed with a number of strategies to lessen or eliminate side effects should they occur, including the use of simple OTC remedies and in some cases prescribing other medications.

I see Alcure M Tab and FM in my Google search, what's that?

We have zero affiliation with that company.
