Taken wrong dose of antibiotics for 2 days can I now take the normal dose?

Hi I was prescribed 250mg antibiotics 2 x 4 times daily on Monday ~ but I misread the label and I’ve been taking 1 x 4 times daily for the last 2 days ~ can I just increase it to the actual required amount now?

Thanks

Taking higher dosages do not cause too much problems, if done for a short period. 2 days is not a long time, so start following the doctors advice.
