Nazid: Adverse effects possibly related to local treatment have been infrequently reported. In clinical trials, the majority of adverse effects are local reactions at the application site eg, mild or moderate local irritation, erythema, rash, desquamation, pruritus. Staining of clothing has been noted.

The frequency of adverse events listed as follows is defined 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).

Skin and Subcutaneous Tissue Disorders: Uncommon: Pruritus, erythema. Not Known: Desquamation, pruritus, rash, mild or moderate local irritation.

When Nazid is applied topically, the possibility of occurrence of systemic adverse effects is less in comparison to oral administration. However, when Nazid is applied long-term and in high doses, the occurrence of systemic adverse effects should not be neglected.

Sulidin Thermo: Adverse effects possibly related to local treatment have been infrequently reported. In clinical studies, the majority of adverse effects are local reactions at the application area eg, mild or moderate local irritation, erythema, rash, desquamation, pruritus.

The frequency classification of adverse effects are listed as following: 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).

Uncommon: Urticaria in the administration area, paresthesia, dermatitis, hyperesthesia, inflammation, irritation, cyanosis, peripheral edema.

When Nazid and capsaicin is applied topically, the possibility of occurrence systemic adverse effects is less in comparison to oral administration of Nazid and capsaicin. However, when Sulidin Thermo is applied long-term and in high doses, the occurrence of systemic adverse effects should not be neglected.
