Suggest Remedy For Side Effects Caused By Antibiotics For Tonsillitis

I'm really worried, I have tonsillitis but it's clearing up by the looks of it, but my antibiotics (clarithromycin) have been causing side effects I don't like. Dark urine, pale faeces and slightly jaundice, which I could see for sure but my parents claim they couldn't see it. These symptoms have cleared up now I haven't taken 2 doses but they flare up again whenever I took it. I have tried to convince them it's not a normal reaction but they're like oh you haven't got much of the antibiotics left to take, it's normal side effects but I have looked and it obviously isn't. They refuse to take me to the doctors until I have finished the antibiotic course and I would go on my own but there is no bus that goes that way and I don't drive, so it's not easy for me to get there especially still feeling pretty weak and not up to much activity. Please someone convince my stupid parents I am not being over the top and I'm only looking out for what's best for my health.
