Abstract


Background: The choice and sources of antimalarial drugs used for self-medication has important implication to the current malaria treatment policies in Kenya. However, data on the choice of antimalarial drugs used for self-medication and their sources remains scanty.

Objectives: The objectives of this study were to determine the prevalence of self-medication, the choice and sources of antimalarial drugs used for malaria self-medication in Kisumu city, Western Kenya.

Methodology: This was a cross-sectional community based study, in which semi-structured questionnaires were randomly administered to 338 participants, in five administrative wards of Kisumu city.

Results: Overall, 250 (74%) of the participants reported self-medication for perceived malaria illness. Of the 250 participants, 219 (87.6%) had used an antimalarial drug(s), while 31 (12.4%) took other drugs (antipyretics and herbs), which they perceived to have antimalarial effect. Artemisinin-based combination therapies (ACT), was the drug of choice for majority 154 (70.3%) of those who had self-medicated. The other antimalarials used were sulphadoxine/sulphalene-pyrimethamine 25 (11.4%), amodiaquine 11 (5%), chloroquine 5 (2.3%), quinine 2 (0.9%), dihydroartemisinin 1 (0.5%), halofantrene 1 (0.5%) and 20 (9%) of participants had used two different antimalarials. The antimalarial drugs were sourced from private pharmacies/chemists (78.4%), general retail shops (29.2%), left over drugs at home (1.6%), or friends, relatives and neighbors (2.8%).

Conclusion: Self-medication for perceived malaria is prevalent in Kisumu city. ACT is the drug of choice for self-medication. However, a substantial proportion of individuals use currently ineffective antimalarials or other drugs, for example antipyretics, with no known antimalarial efficacy. Pharmacies/chemists and general retail shops are the major sources for self-prescribed drugs.

Key words: Self-medication, antimalarial drugs, choices, sources
