These are unwanted effects that you consider are linked to taking a medicine. Side effects also include any effects from: misuse, abuse, an error in the way the medicine has been given or overdose (taking too much medicine). Reports can be made for any medicine (including specials and unlicensed products), any vaccine, herbal product, and complimentary remedies such as homeopathic remedies, blood factors (. factors I to XIII) and immunuloglobulins (. anti-D (RHO) immunoglobulin). You can even report suspected side effects from a drug you think might be happening as a result of interactions with food and drink.

When lidocaine enters a space for which it is not meant, it can cause unwanted side effects and complications. For example, epidural medication administration requires many times the dose of medicine injected directly into the spinal fluid. If lidocaine meant for the epidural space enters the spinal fluid instead, the result is an unwanted spinal block with much more medicine than would normally be used for that purpose. In this situation, the spinal can spread and cause a "total spinal" which temporarily paralyzes breathing and affect the heart rate, conduction and blood pressure in dangerous ways. The same thing can happen with certain peripheral nerve blocks, especially an interscalene block given in the neck before shoulder surgery, since the epidural and spinal spaces are close to the injection site. For this reason, these blocks are (or should) only given by highly-trained professionals who are also certified in advanced life-saving techniques.
