How Long Do Antidepressants Take to Work?

how long antidepressants take to work

If you have been recently prescribed an antidepressant for Depression, persistent sadness, Anxiety, or another mental health issue, one question may sound louder than the rest in your head: “Doctor, how long will this medicine take to work?”

It is a valid question. When months of feeling down and without any hope have shaken your whole world, you crave to feel better now. You cannot stand waking up at odd times at night, being unable to fall asleep when your head hits the pillow, having no interest in food or fun activities your friends used to drag you into, and feeling like your brain is covered in concrete during the daytime.

However, there is one problem with your plan. Antidepressants are not painkillers; they do not work in hours or even days but rather in weeks and even months.

During the first few days, you may see some changes in sleep patterns and appetite, increased anxiety, or reduced energy, but improvements in mood and Depression symptoms may take a few weeks. It may raise many questions: “Is it normal that the medicine did nothing after two weeks?” “Why am I experiencing unpleasant side effects?” “How long will I need to take the medication for it to start working?” “What should I do if it does not work at all?”

You should not worry; let’s discuss everything concerning antidepressants, how long they may take to work, and your expectations out of them in very simple words.

What are antidepressants?

Antidepressants are medications primarily indicated for the treatment of Depression. Based on the preparation and the disease picture, they may also be prescribed for Anxiety disorders, Panic Disorder, OCD, and some other diseases.

When a person is diagnosed with Depression, this does not just mean he/she always feels only sadness and disappointment. This sadness and disappointment may also be accompanied by sleep disorders, changes in eating habits, irritability, lack of motivation or interest in events, difficulty concentrating, and a sense of constant hopelessness about life.

Antidepressants act on the principle of influencing certain signal molecules in the brain. However, this does not mean that taking these preparations will make a person happy.

In addition, brain activity and the entire body’s response to antidepressants may require some time for adaptation, during which the positive effects of the drugs become noticeable.

That is why antidepressants are generally given several weeks to show their effect, rather than being judged after only a few days.

The experience can be different for different people. The medicine being used, its dose, your symptoms, the duration of them, and the way your body reacts all contribute to this.

It may help to see it in phases.

During the first 1–2 weeks

During the first few days of first week, you may not experience significant improvement in your Depression or Anxiety symptoms. During this period some people may find changes in sleep, appetite, energy, or restlessness before they perceive any improvement in their mood.

You may also feel that nothing much has changed yet. This is not necessarily an indication that the medicine is failing.

Around 2–4 weeks

Some people start feeling gradual improvement during this time, for example, sleeping better, being slightly less anxious, or finding everyday tasks a bit easier.

However, improvement in mood is not guaranteed to happen during this period for everyone.

Around 4–8 weeks

For many antidepressants you use, several weeks are required to properly assess the response to the given treatment. At this point, some people may notice an improvement in their Depression or Anxiety symptoms.

This duration is not necessarily fixed for everyone, and the time can vary depending on the medicine, condition being treated, and your personal response to treatment.

So if you do not feel significantly better after days or a couple of weeks, it does not necessarily mean the medicine has failed.

What are the side effects you may experience after starting to take an antidepressant?

When you start to take an antidepressant, you may experience some side effects before experiencing the main beneficial effects of the treatment.

For example, you may feel

  • Nausea or vomiting
  • Headache
  • Increased sleepiness or changes in sleep
  • Restlessness or slight increase in anxiety
  • Changes in appetite
  • Stomach discomfort

Not everyone will experience these effects, and if they do, they may be mild and subside over time.

If a side effect is bothering you or affecting your daily life, it is better to discuss this with your psychiatrist, as there may be ways to handle it depending on the medicine you are taking.

Altering the dose or stopping the medicine yourself is generally not a good idea.

What if I do not feel better after 1–2 weeks?

This is one of the most common questions after you start taking an antidepressant.

If you took the medicine for two weeks and did not significantly improve, it does not mean that medicine will not work for you; antidepressants often work gradually.

You may even feel that one symptom is improving while the other is still present. For example, your sleep may be getting better, but you may still feel depressed.

Other minor changes can also be relevant when it comes to assessing treatment response.

If after an appropriate period you still feel barely improved or not improved at all, your psychiatrist may reevaluate your symptoms, dose, duration of treatment, side effects, and the overall response to treatment.

Do antidepressants make your mood better immediately?

Usually antidepressants do not make your mood better immediately.

Unlike drugs that relieve specific ailments, such as pain or fever, antidepressants do not act right away. A noticeable improvement in mood and other symptoms usually appear after several weeks.

Additionally, sometimes changes in sleep or anxiety may precede a noticeable improvement; therefore, assessing the effectiveness only on the basis of the first few days is not enough to make a conclusion about the inefficacy of the medicine. Instead, you should take into account a general tendency in how your mood and other aspects of your well-being develop over time. You may want to ask yourself several questions about your condition and whether something has improved:

  • Ability to cope with daily responsibilities
  • Sleep
  • Appetite or weight
  • Energy level
  • Thoughts or worries
  • Anxiety
  • Ability to concentrate
  • Sexual function
  • Mood in general

A change in any of these factors may be significant.

Can anxiety or restlessness develop after starting antidepressants?

Some patients, when starting antidepressants, experience an increase in anxiety, agitation, restlessness, irritability, or a sense of unease. If such side effects occur, do not try to adjust the dose or therapy on your own; instead, consult your psychiatrist. He or she will determine whether these side effects are connected with antidepressants and whether the adjustment of the therapy is required.

In case you experience a rapid worsening of mood or develop thoughts of suicide or self-harm or feel that you cannot control your actions and act safely, you should immediately contact a psychiatrist.

Can antidepressants be ineffective?

Sometimes the first antidepressant may be ineffective. It is essential to understand that in this case, antidepressants do not necessarily ineffective: the ineffectiveness of the first drug may be connected with the individual characteristics of your body and the peculiarities of your condition.

On the basis of an analysis of your case, including the dose of the drug, its dosage form, duration of therapy, possible side effects, and the presence or absence of other diseases, your psychiatrist will determine whether there is a need to adjust your therapy.

It is unacceptable to change the dose or cancel the medication on your own: consult your psychiatrist and explain the situation in detail. He or she will determine what actions to take.

Can you stop an antidepressant once you feel better?

This is another frequently asked question.

When your condition starts to improve, it is tempting to assume that you will not need the antidepressant any longer.

However, improvement in your symptoms does not always mean that it is the right time to stop an antidepressant.

Many antidepressants carry a risk of discontinuation symptoms if they are stopped suddenly. Moreover, the length of antidepressant treatment varies depending on your individual case.

Therefore, when you are starting to feel better, it is advisable to consult your psychiatrist before considering any changes to your treatment, instead of stopping the medication abruptly.

Can you take antidepressants along with psychotherapy?

Yes, some people benefit from a combination of psychotherapy and pharmacological treatment.

Psychotherapy, including counselling and different types of talk-therapy, can help you explore your thoughts, feelings, stresses, relationships, and other relevant issues, whereas antidepressant medication may help with managing your symptoms.

However, everyone’s situation is unique, so determining which course of action is best for you requires a thorough assessment by your psychiatrist.

What can I do while waiting for the medicine to work?

While you wait for the medication to start working, there are a few things you can do to support your treatment.

You should aim to maintain a regular sleep schedule and engage in light physical activity.

Moreover, staying in touch with your loved ones can be beneficial in your treatment, as social connection and emotional support from people you care about and who care for you can positively affect your well-being.

On the other hand, Depression can make you feel exhausted, regardless of whether you have been active or not.

If you find it hard to keep up with your routine, do not blame yourself for being inactive.

Recovery is a complex, multi-step process, which requires time and antidepressant treatment.

When should I speak to my psychiatrist again?

If you have any concerns about your treatment, you should not wait for your next appointment.

Contact your psychiatrist whenever:

  • The side effects of your medication become intolerable
  • Your anxiety or agitation becomes extreme
  • You do not see any improvement following an adequate treatment
  • Your condition begins to deteriorate
  • You experience any unusual or unanticipated difficulties after starting antidepressant medication
  • You have any suicidal thoughts

Secondly, antidepressants normally start working within a month – meaning you will feel a difference in your mood and symptomatology.

However, the most crucial step is to communicate openly with your psychiatrist and tell him or her about your concerns. Never change the dosing schedule or abruptly stop taking the medication on your own.
