Available in 250 mg tablets, it works by inhibiting the enzyme aldehyde dehydrogenase, causing unpleasant reactions when alcohol is consumed. It must be taken exactly as prescribed, typically starting at 500 mg daily before reducing to a maintenance dose of 125–500 mg.

You should be aware of the following precautionary guidelines if you plan to order Disulfiram online:
If you forget to take a dose of Disulfiram, take it as soon as you remember—but only if it's within 12 hours of your scheduled time. If more than 12 hours have passed, you can skip the missed Disulfiram dose and continue with your daily schedule. Never double up to make up for a missed Disulfiram dose, as this can increase the risk of side effects.
An overdose of Disulfiram is rare but potentially serious. Symptoms may include confusion, vomiting, low blood pressure, seizures, difficulty breathing, or even coma. If you suspect a Disulfiram overdose, whether accidental or intentional, call the Poison Control Helpline at 1-800-222-1222 for expert guidance.
