Two rough shapes of low mood are worth telling apart: the irritable, restless, crabby kind, and the flattened, heavy, nothing matters kind.

They ask for different things. The agitated version often tolerates and even welcomes something sedating, while the flattened version needs whatever…

Match the tablet to the person rather than to the diagnosis. For someone flattened and slowed who has said clearly that they will not accept sexual side effects, paroxetine is close to the worst choice available.

It is the most sedating in the class, the least activating, and carries a high risk of exactly the effect they ruled out, with weight gain and the…

If you are the therapist, hand the prescriber the profile and leave them the pick. What you hold that they do not is what this person is like across a week, and what they will absolutely not tolerate.

So write those two things down and send them: the presentation, in plain description rather than jargon, and the non-negotiables. Not a drug name.…

A genetic test can tell you how quickly your body clears a medicine. It cannot tell you whether that medicine will lift your mood, and it helps to keep those two questions apart.

Where these panels earn their place is in dosing and tolerability. Someone who breaks a drug down slowly may need less of it, and someone who clears…

Some antidepressants take weeks to build up and weeks to clear, so both the improvement and the aftermath run on a slower clock than you would expect.

Fluoxetine is the usual example. It and the substance it turns into stay around a long time, which means a fair trial is counted in weeks and…

Some newer antidepressants do two jobs in a single tablet: the familiar one of keeping serotonin available, plus a direct nudge at the receiving end.

This is worth knowing because it explains what a person actually feels. A drug with a second action brings a second set of effects, wanted and…

No option comes without a cost. The useful question is not which medicine has side effects, it is which side effects you could live with.

One drug may unsettle your stomach for a fortnight and leave your sex life alone. Another may be kind to the stomach and flatten desire for as long…

If the worst part of low mood is that your thinking has gone foggy, say so specifically. Concentration can be treated as a target of its own rather than as something that will tidy itself up later.

Depression and attention problems overlap enough that the fog often gets filed under whichever label arrived first. Naming it separately gives you…

Heaviness in the body, aching, and a tiredness that sleep does not touch are part of low mood. They are not a separate complaint to raise another time.

There is a group of antidepressants that add a second action aimed partly at these bodily symptoms, which is one reason a prescriber may lean that…

Before deciding a medicine did not work, check that it was taken at a dose and for a length of time that could have worked.

Venlafaxine is the standard example. At low doses it behaves much like a plain SSRI, and the second mechanism people choose it for only comes in…

Raising a dose does not simply raise the benefit. It raises everything the drug does, including the parts nobody was asking for.

As the amount climbs, a medicine begins touching things it barely touched before, which is why new side effects can appear at a higher dose of…

A newer version of a familiar medicine is usually a tidier version rather than a leap, and tidier is still worth something.

Desvenlafaxine is venlafaxine after the liver has done its work, given directly. The point of that is fewer differences between people who process…

If pain is part of what you are carrying, bring it into the same conversation as the low mood. They are not two separate appointments.

The pathways that dampen pain and the ones involved in mood overlap, and one of the antidepressants is licensed for nerve pain and long term…

Sometimes what is most missing is not mood but drive: the flat, cannot get started feeling. That can be named as the target in its own right.

Antidepressants lean in different directions, and one or two are weighted more towards the system carrying energy and alertness than towards…

Most antidepressants share a family resemblance. Bupropion does not, so much of what you have read about the others simply does not apply to it.

It works on the systems carrying drive and alertness rather than on serotonin, which is why its effects, wanted and unwanted, sit at an angle to the…

A medicine that lifts drive is not the same as one that settles anxiety, and for some people the energising kind makes the worry louder.

Bupropion is the clearest example: often good for flatness and lack of motivation, often unhelpful on its own when anxiety and a racing, sleepless…
