Amphetamine and Captagon withdrawal symptoms

Reviewed by: Dr. Mahmoud El-Sawy Last updated: September 28, 2026 10 min read
The short answer

Amphetamine and Captagon withdrawal symptoms usually begin within hours to a day of the last use with a “crash” phase of long sleep, exhaustion, hunger and depression. Acute symptoms peak during roughly the first week and then fade gradually, while low mood, cravings and disturbed sleep may continue for weeks. Withdrawal is mostly psychological, but severe depression can be dangerous.

  • It does not usually cause seizures or direct physical danger the way alcohol and sedative withdrawal can.
  • The most dangerous parts are severe depression, thoughts of self-harm, and relapse.
  • Most Captagon in circulation is based on amphetamine, so the withdrawal from each is very similar.

Why does withdrawal happen after stimulants?

During use, amphetamine forces the brain to release large amounts of dopamine and norepinephrine, so the brain adapts by becoming less sensitive to these neurotransmitters, while the body also drains its stores of energy and sleep. When use stops, this deficit is exposed: exhaustion appears instead of energy, depression instead of euphoria, and long sleep and hunger instead of sleeplessness and loss of appetite.

Because most illicit Captagon tablets contain amphetamine, people who stop them go through almost the same course. The caffeine found in many of these tablets may add headaches and irritability in the first few days.

Timeline of Amphetamine and Captagon Withdrawal

The course differs from person to person depending on how long and how heavily they used and on their psychological state, but medical references usually describe it in three overlapping phases:

  1. First hours to 3 days
    The crash

    Severe exhaustion and very long sleep, excess hunger, low mood, anxiety and irritability, with cravings that can be strong.

  2. About the first week
    Acute withdrawal

    Depression and mood swings, exhaustion with insomnia or excessive sleep, disturbing dreams, muscle aches, poor concentration and cravings.

  3. About week 2 to week 4
    Subacute phase

    Symptoms improve gradually, with low mood, disturbed sleep and waves of cravings continuing.

  4. After the first month
    Protracted withdrawal

    In some people, loss of enjoyment, low energy and occasional cravings continue for weeks or months, especially after long-term use.

Is amphetamine and Captagon withdrawal dangerous?

Unlike alcohol and sedative withdrawal, stimulant withdrawal does not usually cause seizures or life-threatening physical complications. But that does not mean it is safe or easy:

  • Severe depression: It can be deep in the first days, and in some people it comes with thoughts of self-harm.
  • Persistent psychosis: If the person had suspiciousness or hallucinations during use, they may continue for days after stopping and need treatment.
  • Relapse: Cravings and the crash push many people to return to use quickly.
  • Mixing other substances: If the person also uses sedatives, alcohol or pregabalin, withdrawal from those substances can carry real physical danger.

What determines the severity and length of withdrawal?

  • Duration and frequency of use: Long-term daily use means more severe and longer withdrawal than occasional use.
  • Pattern of heavy binges: Consecutive days without sleep make the crash afterward more severe.
  • Tablet composition: In Captagon, ingredients may differ from one tablet to another, so withdrawal differs in ways that are hard to predict.
  • Psychological state: Existing depression, anxiety or ADHD makes withdrawal harder.
  • Accompanying substances: Mixing stimulants with sedatives or alcohol complicates withdrawal and increases its danger.

Why does withdrawal need medical supervision?

Although stimulant withdrawal does not usually require medication to prevent physical complications, medical follow-up makes a big difference:

  • Assessing depression and the risk of self-harm, and monitoring them daily.
  • Treating psychosis or agitation, if present, with medications chosen by the doctor.
  • Regulating sleep, nutrition and fluids after a long period of neglect.
  • Detecting withdrawal from other accompanying substances, which can be dangerous.
  • A safe environment away from the substance during the days when cravings are at their strongest.
  • A direct transition to a psychological treatment program that prevents relapse.

The page on amphetamine and Captagon addiction treatment explains what comes after this stage: psychological and behavioral therapy and follow-up.

How can the family support someone going through stimulant withdrawal?

  • Accept the long sleep and hunger in the first days, as they are part of the body's recovery.
  • Provide healthy food, enough fluids and a quiet environment.
  • Treat irritability and sadness as symptoms, not personal insults.
  • Watch their mood closely, and never ignore any talk of hopelessness or self-harm.
  • Reduce access to the substance and to money in the first weeks.
  • Encourage them to continue treatment after the acute symptoms are over.

Protracted withdrawal: why doesn't mood return right away?

After the acute symptoms end, many people complain of feeling “switched off” emotionally, low energy and enthusiasm, and cravings that come in waves when they are exposed to triggers such as exams, staying up late, or friends who use. This is because the brain's reward circuits need time to regain their normal sensitivity. This phase is managed with psychological therapy, regular exercise, regulating sleep, and treating depression if it persists, and knowing that it is temporary helps a great deal in getting through it.

Signs of poisoning from amphetamine and stimulants: call the ambulance on 123 immediately

  • A very high body temperature with hot skin or heavy sweating
  • Chest pain or pressure, or a very fast or irregular pulse
  • Seizures, muscle stiffness or an uncontrollable tremor
  • Severe agitation, hallucinations, or confusion and loss of awareness of place and time
  • A sudden severe headache, weakness on one side of the body, difficulty speaking, or loss of consciousness

Call the ambulance on 123 immediately, move the person to a quiet, cool place away from crowds, and talk to them calmly without violent restraint. If they lose consciousness, place them on their side and stay with them until help arrives, and do not give them any other substance or stimulating drinks.

Ask on WhatsApp
When do amphetamine withdrawal symptoms start?

They usually begin within hours to a day of the last use, with a crash phase of exhaustion, long sleep, hunger and low mood.

How long does Captagon withdrawal last?

Acute symptoms are most severe in roughly the first week, then improve gradually over weeks, and in some people low mood and cravings may continue longer.

Is Captagon withdrawal the same as amphetamine withdrawal?

In most cases, yes, because most Captagon tablets contain amphetamine, but their unknown composition may make withdrawal less predictable.

Can you die from stimulant withdrawal?

Withdrawal itself does not usually cause fatal physical complications, but severe depression, thoughts of self-harm and withdrawal from other accompanying substances can be dangerous and need monitoring.

Why do I sleep so much after stopping Captagon?

Because the body is making up for days of sleeplessness and exhaustion, and because the brain has a temporary shortage of stimulating neurotransmitters. Long sleep in the first days is expected and gradually improves.

Is there a medication that stops amphetamine withdrawal?

No medication is approved specifically for this, but the doctor may treat particular symptoms such as severe insomnia, agitation, psychosis or depression, along with psychological support and follow-up.

Does sleep return to normal after amphetamine withdrawal?

Usually yes, but it takes time. At first sleep is very long, then intermittent insomnia may follow, and sleep settles gradually over weeks with a fixed routine and physical activity.

Can you stop Captagon at home?

It may be possible in some mild cases with medical follow-up and strong family support, but a residential stay is preferred when there is severe depression, psychosis, use of other substances or failed previous attempts.
