most prescriptions come with little pamphlets that list all the side effects of them, not sure if that applies to antibiotics or not though.
They should do.
When you go to the pharmacist to collect the prescription they should give you the bottle in a bag, and in the bag should also be a list of instructions, symptoms, advice and warning signs regarding taking the antibiotic.
If it's in a box (which I've not generally heard of with pill/tablet based antibiotics) then the pamphlet may be inside the box, as they are when you purchase over-the-counter painkillers.
Generally speaking you're okay to just follow your doctors orders, which is to just take the pills/tablets.
But reading the pamphlet is also good to do. And it's recommended you keep ahold of the pamphlet until you've finished the course of antibiotics, since side-effectsmight not appear until towards the end of your course, so you'll want the pamphlet available to know if your symptoms are normal and what to do about them.
But in general, if there are any side-effects that you're unsure about, then just speak to your doctor.
