Purpose: Methotrexate (MTX) is still the main treatment option for rheumatoid arthritis (RA). There is no consensus on drug administration routes and dosage when administered alone or in combination with other drugs. This study aims to identify the effects of early administration of a combination therapy containing high dose subcutaneous (SC) MTX on RA management. Materials and Methods: Forty-five patients with RA who newly diagnosed were divided into two groups randomly. The patients who took 12.5 mg SC MTX per week in the first 4 weeks defined as a "low dose group". The patients who took 25 mg SC MTX per week in the first 4 weeks defined as a "high dose group". Then, patients of both groups continued with 12.5 mg oral MTX per week. Clinical and laboratory findings, disease activity scores and response rates of the patients were recorded at the beginning, 3rd months and 6th months. Results: There was no significant difference between the two groups at 3rd month’s values. There were statistically significant improvements at 6th month’s values. Values were as follows in low and high dose groups: mean DAS28-CRP (3.5 vs 2.7), VAS pain score (3.3 vs 1.6), and TJC28 (3 vs 1.5), respectively. Conclusion: Early administration of high-dose SC MTX effectively controls disease activity and increases the quality of life in RA patients.
