I did a mistake and was told that somebody I slept with without protection had chlamydia.. So I went on superdrug and bought the antibiotics to clear the infection. However, I took one tablet at 8pm and the next at 8am (thinking it was two doses), on the box I found that it should've been one dose, taking both of them at the same time.. Do I need to order the tablets again and follow the correct dosage or doesn't it matter? Thanks.
