It is a good idea to wait to see your psychiatrist if you have concerns about taking your medications. As you noted, side effects can cause additional problems, so being sure you are taking medication you and your doctor feel will help is important. You need to balance the relief from your symptoms with any possible side effects from your medication. If you find the side effects too distressing, the medication will not be effective for you. Also, be sure to ask your doctor how long you should allow for the side effects before you consider staying on the medication or switching to a new one. Also, ask how long will it take for the medication to be at full strength and begin to help your symptoms.
Be aware that many people need to try several different medications before they find ones that work for them. Although medication is a great treatment, it is not an given that medications work in the same way for everyone. The combination of the medicine with your body chemistry may work or it may not. So finding what works for you is important.
You may also want to take this time to explain any further symptoms you have so the doctor has a clear picture of your experiences and will then know the right medication to use to help you.
