Description
Alconol 500 mg Tablet (Disulfiram) — Support for staying alcohol‑free
Alconol 500 mg is a prescription tablet used to help people with alcohol dependence stay off alcohol. The active ingredient is disulfiram 500 mg. It doesn’t cure addiction on its own, but it adds a powerful layer of accountability if you drink alcohol while taking it, you’ll feel very sick, very fast. That strong deterrent gives you space to work on recovery plans, counseling, and healthier routines without the constant pull to drink.
What it’s for (and why people use it)
- Helps maintain abstinence in alcohol use disorder
- Works as a deterrent therapy when paired with counseling/support
- Useful if you’ve tried to quit and keep relapsing into slips or binge cycles
How it works
Your body normally breaks down alcohol in steps. Disulfiram blocks a key
enzyme (aldehyde dehydrogenase). So if you drink, acetaldehyde builds up in your system and makes you feel awful flushing, pounding headache, nausea, vomiting, chest tightness, fast heartbeat, anxiety. The message your brain gets is clear: alcohol = bad time. That wall between you and a drink helps you stick with your no‑alcohol plan.
What you’re getting
- Strength: 500 mg disulfiram per tablet
- Form: Film‑coated oral tablet
- Pack: Varies by brand; check your box for exact count
How to use (follow your clinician’s plan)
- Start after you’ve stopped drinking: usually at least 12 hours after your last alcoholic drink. Many doctors prefer 24 hours.
- Take at the same time each day, with or without food. Morning dosing is common.
- Don’t stop or change your dose on your own. If you miss a dose, take it when you remember unless it’s close to the next one then skip and continue. No doubling.
- Some providers give the first dose in the clinic to review safety and answer questions.
Alcohol is hidden in more places than you think
