What side effects can you get with SSRI’s and what do you need to know about prescribing them?

A

SSRIs side effects: hyponatraemia (SIADH) in elderly, nausea, headache, GI upset, sexual dysfunction, insomnia, agitation, restlessness, anxiety.
During the first few weeks of treatment, there is a potential increase for agitation, anxiety and suicide risk - especially younger patients.
In general, an antidepressant effect is usually seen within 2-4 weeks of starting treatment.
Treatment should be continued for at least 4 weeks (6 weeks if elderly) before considering switching.
Antidepressants should be taken for at least 6 months after they have recovered, to reduce the risk of relapse. People who are at high risk of relapse may need to take them for longer than this.

Measure plasma lithium levels 1 week after starting lithium and 1 week after every dose change, and weekly until the levels are stable.

Aim to maintain plasma lithium level between 0.6 and 0.8 mmol per litre in people being prescribed lithium for the first time.
Measure the person’s plasma lithium level every 3 months for the first year.
After the first year, measure plasma lithium levels every 6 months
