Practices

The chemistry story runs backwards from how it is usually told. Nobody found a low chemical and then built a drug. They noticed what certain drugs did to mood and reasoned back to what must have been missing.

Reserpine emptied out the monoamines and people became depressed. Iproniazid and imipramine raised them and mood lifted. Out of that came the account…

Depression is not one thing with one address. Fatigue, blank concentration, lost libido and the loss of pleasure do not all come from the same place, so it helps to name which one you most want moved.

This is why two people with the same diagnosis get offered different tablets. A flat, pleasureless presentation points one way, a fatigued and achey…

Nearly all of them do the one thing: keep a monoamine hanging about in the synapse for longer. So when you hear that some other tablet is stronger, be a little sceptical.

Head to head, the differences in how much they lift mood are modest. Where they really differ is in everything else they do to you, and in how well…

SSRIs became the default for four reasons, and being more effective is not among them. They are easier to tolerate, taken once a day, far safer in overdose, and cheap as generics.

Tricyclics match them for lifting mood and are dangerous in overdose because of what they do to the heart. MAOIs carry food and drug interactions…

The standing side-effect list is sexual difficulty, less appetite, an unsettled stomach, disturbed sleep and headache. Sexual side effects are common, and almost nobody raises them unprompted.

So ask directly, and ask about sleep while you are there. People do not usually announce these things. They quietly stop taking the tablet and say…

Stopping suddenly can bring lethargy, nausea, irritability and headache within a few days. That is discontinuation, not the illness coming back.

Timing is the giveaway. Withdrawal starts within days of the last dose and often has a particular feel to it: dizziness, odd electrical zaps, a…

Discontinuation gets mistaken for relapse constantly, by clients and by clinicians. The mistake runs in both directions and both directions cost something.

Read withdrawal as relapse and a person concludes they will need the tablet for life, when what they needed was a slower taper. Read a real relapse…

Never come off an antidepressant on your own. The taper belongs to the prescriber, and for some drugs it needs to be slower and longer than people expect.

The moment to raise this is before anybody acts, not afterwards. If a client is feeling better and starting to think about stopping, that thought is…

Four things carry most of the difference within the class: how much it sedates, how much it activates, what it does to weight, and what it does to sex.

Before anything is chosen, write down which of the four you cannot live with. Almost nobody is neutral about all four, and the one you will not…

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…

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…
