These reactions usually occur early in the treatment, and tend to gradually lessen over time.
Tabulated summary of adverse reactions: The adverse reactions are classified by System Organ Class and frequency, using the following convention: very common (≥ 1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), not known (cannot be estimated from the available data) and were reported with Epiduo Forte 0.3% / 2.5% gel in vehicle-controlled Phase 3 clinical study (see Table 3).

Skin-related adverse events were more frequent with Epiduo Forte 0.3% / 2.5% gel than Epiduo gel (Adapalene 0.1% / Benzoyl peroxide 2.5%) as compared to vehicle. In the pivotal study (see Pharmacology: Pharmacodynamics under Actions), 9.2% of subjects in the combined population treated with Epiduo Forte 0.3% / 2.5% gel had skin-related adverse events and 3.7% in the population treated with Epiduo gel compared to Vehicle Gel group (2.9%).
In addition to some of the previously mentioned, other adverse drug reactions were reported with Epiduo gel (Adapalene 0.1% / Benzoyl peroxide 2.5%), the previously approved fixed combination of adapalene and benzoyl peroxide: Clinical trials: Other adverse drug reactions reported in clinical trials with Epiduo gel are irritative contact dermatitis (common) and sunburn (uncommon).
