Night Says:

Hello, I took 50mg to help me stop drinking alcohol and/or drink less. The first time I took it I became very dizzy, irritable and had a throbbing headache. I definitely didnt want to drink but I also don't want to feel like that again. Is it possible that the dosage is too high. Should I try taking a lower a dosage? Its been five days since I took it and Ive tried drinking and can only have one or two drinks and then I don't feel like drinking and thats just from that one 50mg pill. Im happy that Im not drinking much but I dont want to go through that again. I am not on any opiods.

Hello, Night! How are you?

All medications carry the risk of causing side effects and that sounds like what you experienced. However, they are usually transient and will wear off in a few weeks, once your body gets used to the medication, so you shouldn't lower your dosage, without your doctor's approval.

Other side effects, as listed by the FDA, may possibly include constipation, nausea, drowsiness and muscle pain.

Is there anything else I can help with?

I started 25 mg naltrexone 3 weeks ago for alcohol dependence. I was supposed to go up to 50 after 3 days. Well I felt a little dizzy and no appetite so I have only stayed on the 25mg. It immediately eliminated the wine cravings but I have to make myself eat enough. Wine doesn't even smell good. It is a miracle IMO. I haven't taken the pill the last 2 days and the thought of a drink is not appealing : 0 I plan on asking the Dr tomorrow if I can take it every other day. I don't like putting all the chemicals in my body.

I found the same thing happened the first few days on the medication. I would say if 25mg does the trick then stick with it. But for me 50mg controlled my urge to drink better and over a week the nausea went away.
