Important Safety Information
This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS Common adverse events that occurred in any acamprosate calcium treatment group at a rate of 3% or greater and greater than the placebo group in controlled clinical trials with spontaneously reported adverse events are: accidental injury, asthenia, pain, anorexia, diarrhea, flatulence, nausea, anxiety, depression, dizziness, dry mouth, insomnia, paresthesia, pruritus and sweating ( 6.1 ).

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Clinically significant serious adverse reactions associated with acamprosate calcium described elsewhere in labeling include suicidality and depression and acute kidney failure [ see Warnings and Precautions (5.2), and Adverse Reactions (6.2) ].
The adverse event data described below reflect the safety experience in over 7000 patients exposed to acamprosate calcium for up to one year, including over 2000 acamprosate calcium-exposed patients who participated in placebo-controlled trials.
Adverse Events Leading to Discontinuation In placebo-controlled trials of 6 months or less, 8% of acamprosate calcium-treated patients discontinued treatment due to an adverse event, as compared to 6% of patients treated with placebo.
In studies longer than 6 months, the discontinuation rate due to adverse events was 7% in both the placebo-treated and the acamprosate calcium-treated patients.
Only diarrhea was associated with the discontinuation of more than 1% of patients (2% of acamprosate calcium-treated vs.
0.7% of placebo-treated patients).
5 WARNINGS AND PRECAUTIONS Dose reduction is required for patients with moderate renal impairment ( 5.1 ).
Monitor patients for depression or suicidal ideation and prompt patients, families, and caregivers to report such symptoms to the health care provider ( 5.2 ).
5.1 Renal Impairment Treatment with acamprosate calcium in patients with moderate renal impairment (creatinine clearance of 30 to 50 mL/min) requires a dose reduction [ see Dosage and Administration (2.1) ].
Acamprosate calcium is contraindicated in patients with severe renal impairment (creatinine clearance of ≤30 mL/min) [ see Dosage and Administration (2.1) , Contraindications (4.2) , Use in Specific Populations (8.6) , and Clinical Pharmacology (12.3) ].
5.2 Suicidality and Depression In controlled clinical trials of acamprosate calcium, adverse events of a suicidal nature (suicidal ideation, suicide attempts, completed suicides) were infrequent overall, but were more common in acamprosate calcium-treated patients than in patients treated with placebo (1.4% vs.
Like all medications, Acamprosate Calcium can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
