Most anxiety medications do come with side effects, but for the majority of people, they are manageable. The type and intensity of side effects depend heavily on which class of medication you are taking. SSRIs, SNRIs, benzodiazepines, and beta-blockers all work differently, and each carries its own risk profile.

Common Side Effects by Medication Type

Different classes of anxiety treatment medicines work through different mechanisms. So, they have different side effects on the human body.

SSRIs and SNRIs

Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are the most widely prescribed medications for anxiety and depression. 

Common side effects include:

• Nausea, particularly in the first one to two weeks
• Headaches
• Disrupted sleep
• Increased sweating
• Dry mouth
• Dizziness on standing

Benzodiazepines

Benzodiazepines such as diazepam, lorazepam, and alprazolam act quickly on the nervous system and are usually prescribed for short-term or situational anxiety. Their side effects are distinct from those of SSRIs.

• Sedation
• Memory difficulties
• Coordination problems
• Chance of dependence
• Rebound Anxiety

Beta-Blockers

Propranolol and similar beta-blockers are sometimes prescribed for physical symptoms of anxiety, particularly for performance or situational anxiety, racing heart, trembling hands, or visible flushing.

Side effects to be aware of:

• Fatigue and low energy
• Cold hands and feet due to reduced circulation
• Slower heart rate
• Lightheadedness

Side Effects That Need Immediate Attention

Contact your prescriber or seek urgent advice if you experience:

• Significant worsening of anxiety or low mood
• Thoughts of self-harm or any sudden shift in mood
• Signs of serotonin syndrome, which can include agitation, rapid heart rate, muscle twitching, and high temperature
• Severe allergic reactions, including rash, swelling, or breathing difficulty
• Seizures after stopping benzodiazepines 

How Long Do Side Effects Last?

The majority of side effects from SSRIs and SNRIs peak in the first one to two weeks and then gradually improve as the body adjusts.

Benzodiazepine side effects, such as drowsiness, are present throughout the period of use and do not always diminish over time.

If side effects feel severe or are not improving after a few weeks, that is always a reason to go back to your prescriber. 

Stopping Anxiety Medication

Stopping anti-anxiety drugs abruptly, particularly SSRIs and benzodiazepines, can cause discontinuation effects that are sometimes mistaken for relapse. These include dizziness and electric shock sensations. Always reduce under medical supervision with a planned, gradual taper.
