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 practice.
The safety data for paroxetine are from: 6-week clinical trials in MDD patients who received paroxetine 20 mg to 50 mg once daily 12-week clinical trials in OCD patients who received paroxetine 20 mg to 60 mg once daily 10- to 12-week clinical trials in PD patients who received paroxetine 10 mg to 60 mg once daily 12-week clinical trials in SAD patients who received paroxetine 20 mg to 50 mg once daily 8-week clinical trials in GAD patients who received paroxetine 10 mg to 50 mg once daily 12-week clinical trials in PTSD patients who received paroxetine 20 mg to 50 mg once daily Adverse Reactions Leading to Discontinuation Twenty percent (1,199/6,145) of patients treated with paroxetine in clinical trials in MDD and 16.1% (84/522), 11.8% (64/542), 9.4% (44/469), 10.7% (79/735), and 11.7% (79/676) of patients treated with paroxetine in clinical trials in SAD, OCD, PD, GAD, and PTSD, respectively, discontinued treatment due to an adverse reaction.
The most common adverse reactions (≥ 1%) associated with discontinuation (i.e., those adverse reactions associated with dropout at a rate approximately twice or greater for paroxetine compared to placebo) are presented in Table
Table 3 Adverse Reactions Reported as Leading to Discontinuation (≥ 1% of Paroxetine-Treated Patients and Greater than Placebo) in MDD, OCD, PD, SAD, GAD, and PTSD Trials Where numbers are not provided the incidence of the adverse reactions in patients treated with paroxetine was not > 1% or was not greater than or equal to 2 times the incidence of placebo.
Incidence corrected for gender.

OCD: Nausea, dry mouth, decreased appetite, constipation, dizziness, somnolence, tremor, sweating, impotence, and abnormal ejaculation.
5 WARNINGS AND PRECAUTIONS Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents, but also when taken alone.
If occurs, discontinue paroxetine and serotonergic agents and initiate supportive measures.
( 5.2 ) Embryofetal Toxicity: May cause fetal harm.
Meta-analyses of epidemiological studies have shown increased risk (less than 2-fold) of cardiovascular malformations with exposure during the first trimester.
( 5.4 , 8.1 ) Increased Risk of Bleeding: Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs, other antiplatelet drugs, warfarin, and other anticoagulant drugs may increase risk.
Like all medications, Paroxetine 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.
