There are several important things to consider when taking antidepressants. You should discuss these with a GP or mental health professional.
Antidepressants can react unpredictably with other medicines, including some over-the-counter medicines such as ibuprofen. Always read the patient information leaflet that comes with your medicine to see if there are any medicines you should avoid.
If in doubt, your pharmacist or GP should be able to advise you.
As a precaution, antidepressants are not usually recommended for most pregnant women, especially during the early stages of a pregnancy.
This is because they might be dangerous for your baby.
But exceptions can be made if the risks posed by depression (or other mental health conditions) outweigh any potential risks of treatment.
If you're pregnant and depressed, you should discuss the pros and cons of antidepressants with the doctor in charge of your care.
As a precaution, the use of antidepressants if you're breastfeeding is not usually recommended.
However, there are circumstances when both the benefits of treatment for depression (or other mental health conditions) and the benefits of breastfeeding your baby outweigh the potential risks.
Speak to your doctor for advice.
The use of antidepressants is not usually recommended in children and young people under the age of 18. This is because there's evidence that, in rare cases, they can trigger thoughts about suicide and acts of self-harm in this age group.
Concerns have also been raised that their use could affect the development of the brain in children and young people.
An exception can usually only be made if the following points are met:
You should be wary of drinking alcohol if you're taking antidepressants, as alcohol is itself a depressant and drinking alcohol can make your symptoms worse.
If you drink alcohol while taking types of antidepressants called tricyclic antidepressants (TCAs) or monoamine oxidase inhibitors (MAOIs), you may become drowsy and dizzy.
You're less likely to experience unpleasant or unpredictable effects if you drink alcohol while taking an SSRI or a serotonin-noradrenaline reuptake inhibitor (SNRI) antidepressant, but avoiding alcohol is often still recommended.
The use of illegal drugs is not recommended if you're taking antidepressants, particularly if you've been prescribed a TCA. This is because they can cause unpredictable and unpleasant effects.
In particular, you should avoid taking:
As with alcohol, illegal drugs can make symptoms of depression or other mental health conditions worse.
You should never take 2 different types of antidepressants, such as an SSRI and a TCA, unless advised by a doctor. This is because taking certain combinations of antidepressants can make you feel very ill and can be life-threatening.
If a decision is taken to switch you from 1 type to another, the dosage of the first antidepressant will usually be gradually reduced before the second is started.
St John's Wort is a popular herbal remedy promoted for the treatment of depression.
While there's evidence of its effectiveness, many experts advise against its use, because the amount of active ingredient varies among individual brands and batches, making the effects unpredictable.
You shouldn't take St John's Wort if you're pregnant or breastfeeding, as it's unclear whether it's safe.
Some antidepressants can cause dizziness, drowsiness and blurred vision, particularly when you first start taking them.
If you do experience these problems, you should avoid driving or using tools and machinery.
SSRIs may not be suitable if you have:
SNRIs may not be suitable if you have a history of heart disease or you have poorly controlled high blood pressure.
TCAs may not be suitable if you have:
