Dr. Charogat :

Hi, and thank you for coming here with your question.

Dr. Charogat :

Depending on the dose of naltrexone it can last from 24 to 72 hours. Generally, one 50mg dose is expected to work to a time equal to 24 hours of injected drugs.

Dr. Charogat :

The dizziness and relaxed feeling are side effects, and you need to speak to your doctor to see if your dose should be decreased.

Dr. Charogat :

Does this help?

Dr. Charogat :

Do you have any further questions/?

Customer:

hi

Customer:

thank you for your reply

Customer:

I am currently taking 50 mg once per day

Dr. Charogat :

Did you need more information?

Customer:

so it will block opiates for 72 hours?

Dr. Charogat :

That is typically the dose that will take you through 24 hours. BUT, as you are having side effects it is likely that it will last somewhat longer or that you should be taking a bit of a smaller dose.

Customer:

as I am an alcoholic, what would happen If i slip

Customer:

and have a drink?

Customer:

Am I at huge danger then?

Customer:

I am going to take the medication as prescribed because I really want to get off alcohol

Customer:

I am just wondering as i am an addict I need to know

Dr. Charogat :

That can cause the levels of both drugs (alcohol and naltrexone) to be multiplicative (ie it is not that you add the effect of the each to make a total of both, but rather they multiply each other - so each one becomes much more potent)

Dr. Charogat :

So, yes, it would be much more dangerous if you were to drink while taking it.

Customer:

would the effect of alcohol be stinger?

Customer:

stonger?

Dr. Charogat :

yes

Customer:

I dont understand, is not it blocking the opiate?

Dr. Charogat :

It is not blocking the alcohol. Is that what you are asking?

Customer:

yes

Customer:

revia, naltrexone

Customer:

I thought it was an opiate blocker

Customer:

which means that I would not get an effect when drinking?

Dr. Charogat :

It is an opiate blocker, but it can be overwhellmed

Customer:

like no pleaseure

Customer:

how do you mean?

Dr. Charogat :

I am beyond embarrassed. I was reading one word and thinking another.

Dr. Charogat :

If you would like I would opt out. Otherwise I would hope you'll be willing to give me a chance to start this conversation over.

Dr. Charogat :

It is an opiate blocker.

Customer:

now I don't understand

Customer:

did you think I asked another question?

Dr. Charogat :

(I've been answering most of your questions regarding the drug methadone - that is used to help people come off drugs as well -- this is VERY different than the question you were actually asking)

Customer:

ook lets start it over again

Customer:

oh i don't know what that is

Dr. Charogat :

Thank you so much for giving me the chance.

Customer:

ok could you please reply to my question

Customer:

sure

Customer:

just want an answer

Customer:

:)

Dr. Charogat :

Okay.... now for NALTREXONE....

Customer:

hi Im on naltrexone and just wondered how long it prevents/ blocks opiates for?I am also feeling a bit relaxed, dizzy is this a side effect?

Dr. Charogat :

It should work for 24 hours.

Customer:

ok

Customer:

and does it block opiates?

Dr. Charogat :

When the dose is increased then often it will work for longer. (up to 72 hours)

Dr. Charogat :

It does block opiates

Customer:

so If I drink I will not get an effect?

Dr. Charogat :

Naltrexone can cause you to feel sluggish, and overly tired.

Customer:

i take 50 mg

Dr. Charogat :

If you drink you will likely get a much lower effect than you would if you weren't taking the medication.

Dr. Charogat :

50 mg is the dose that is used for 24 hours.

Customer:

ok

Dr. Charogat :

For how long have you been taking naltrexone?

Customer:

so how long does it make me dizzy?

Dr. Charogat :

I ask because over time the side effects you are feeling should be reduced

Customer:

for 24 hours?

Dr. Charogat :

lol -- I was answering as you were typing.

Customer:

ok

Customer:

two days

Dr. Charogat :

Okay, you can talk to your doctor about it - just to let him/her know that you are experiencing these side effects, but if they are not too bothersome you should try for a few more days and see if they become less.

Customer:

but I feel tired/ relaxed

Dr. Charogat :

That feeling should decrease over a few days.

Customer:

ok

Dr. Charogat :

If this side effect continues then your doctor might want to change your medication all together.

Customer:

but does the side effect last 24 h?

Dr. Charogat :

Before starting this medication your doctor most likely made sure that your body was not dependent on the medication.

Dr. Charogat :

(The side effect can last the entire 24 hours, but more likely will start wearing off noticeably by around 18 hours)

Dr. Charogat :

Was this prescribed for your drinking? or were you using other drugs as well?

Customer:

drinking

Customer:

is it dangerous to drink? what if I slip and have a drink?

Dr. Charogat :

Did your doctor talk to you about taking antabuse (disulfiram)?

Customer:

DO i need to call emergency?

Customer:

Or what will happen?

Customer:

this is not antabuse

Dr. Charogat :

If you slip and have a drink you most likely will not have the effect you are used to.

Customer:

this is naltrexone

Customer:

ok, what will happen then? sick?

Customer:

or just no please

Dr. Charogat :

I know this isn't antabuse -- I was asking about antabuse because that is often found to be more effective. The reason it is found to be more effective is because drinking while on antabuse will make you sick.

Customer:

ok

Customer:

yeah Im just binge drinking on weekends

Dr. Charogat :

This will not make you sick - just decrease the effects that you normally have.

Customer:

so I have not gotten to the point where I drink everyday

Customer:

ok

Dr. Charogat :

It seems that antabuse would be a better medication for you in this case.

Customer:

he recommended naltrexone

Customer:

why do you think so?

Dr. Charogat :

Antabuse can be dangerous if you drink. Possibly that is why he prescribed naltrexone - so that you wouldn't get the good feeling from the alcohol - but at the same time you wouldn't be putting yourself into real danger.

Dr. Charogat :

Drinking while on antabuse can be bad enough to need emergency hospitalization.

Dr. Charogat :

But, that is the reason I think it is a better medication - ESPECIALLY if you have normally been staying sober all week anyway.

Customer:

ok thank you for your reply

Customer:

I appreciate it

Dr. Charogat :

I have to admire you

Dr. Charogat :

Kicking an addiction (even just a weekend one) is a big job. It is great that you've gone to get help.

Customer:

thank you

Customer:

yes want to feel well and also not hurt my loved ones

Customer:

and myself

Customer:

its damage

Dr. Charogat :

Please don't cheat yourself by 'testing' how you will feel if you drink while on the naltrexone -- it will only set you up for failure. It isn't worth it after your hard work that started with seeing the doctor about this.

Customer:

alcohol is damage

Dr. Charogat :

It is.

Customer:

thank you and I won't

Dr. Charogat :

Alcoholism is very personal to me. My husband (an alcoholic) no longer lives with us, and has lost everything - including our home - and left me to care for our disabled child.... all because of alcohol.

Customer:

Thats very sad to hear

Dr. Charogat :

When I hear someone is an alcoholic and trying to get treatment BEFORE ruining their lives and the lives of their loved ones, I have the utmost respect.

Customer:

I have alcoholism in my family

Customer:

I don't want to end up as them

Dr. Charogat :

I just don't want it to happen to anyone else. The ONLY reason I shared this is to give you more power to keep yourself sober and not ruin your and your loved one's lives.

Customer:

therefore i seek help at an early stage

Dr. Charogat :

Yep.

Customer:

I hope you will find peace

Dr. Charogat :

Like I said.... I have the utmost respect.

Customer:

good luck with everything

Dr. Charogat :

Thank you :) I really was only sharing to help you keep your conviction strong.

Dr. Charogat :

Good luck. Your family is lucky that you recognize and are dealing with this.

Customer:

Yes I will continue

Customer:

its hard but life in recovery is better

Dr. Charogat :

Is there anything further I can help with?

Customer:

thats what I hear

Customer:

heard

Customer:

all good thanks and thank you for sharing
