Anxious about ranitidine side effects

My doctor prescribed me to go on ZANTAC, but it was out of stock so i got another brand which is RANITIDINE SANDOZ. Chemist said its the same thing. Well i heard that a side effect it can cause is vomiting! I'm afraid of vomiting and now im too scared to take the medicine. Especially because i probably dont actually need it. The doctor just said to take 1 tablet once a day for 2 weeks to see if it helps, but really the worst symptom i have is burping and occassional nausea, I mean yesterday my stomach had a burning sensation. But anyway i feel like i probably dont need the medication which makes me worry more about side effects.

I have never had side effects to medication in the past that i know of, but still i am just concerned. I worry too much. But how common exactly are side effects? Even if side effects are common do you think vomiting would be the most likely side effect to occur? 

Hi.

I was recently diagnosed with anxiety but have had it the past 6 years unknowingly. To calm my symptoms down I often listen to relaxing music and meditate in a dark room. I'm from Ireland and was prescribed an anti depressant called bedranol which is not really needed once I relax via meditation.

Have you tried the medication? Are you having any side effects from it?  Are you reading the side effects about the medication and possibly overthinking about the possible side effects?

I still havent tried the medication. I'm too scared of the side effect of vomiting, i mean im fine with any other side effect, but vomiting is the one that worries me and i really dont think im going to take the medicine if vomiting is possible
