Effects to watch for

Selank

What is common, what is less so, and what to do if something is out of the ordinary.

What most people notice

A small injection-site reaction that clears on its own.

Mild fatigue or a feeling of detachment can appear in the first few days.

What can also happen

  • A mild headache.
  • Mild nausea.
  • Brief dizziness.
  • More rarely, a somewhat flat mood.

To reduce these effects

  • Give the injection at a regular time.
  • Avoid alcohol on the day of the injection.
  • Change the injection site every time.
  • Do not raise the dose on your own.

When to talk to a professional

With this product, especially if you notice:

  • Significant drowsiness or unusual confusion.
  • Low mood that sets in.
  • A reaction that lasts after stopping the product.

If a symptom is severe, lingers or worries you, stop the product and talk to a healthcare professional. An immediate reaction after the injection, such as trouble breathing or swelling of the face, needs medical care right away.

Specific to this product

  • It is not recommended during pregnancy and breastfeeding.
  • If you take medication for anxiety or depression, or if you live with a significant psychiatric condition, talk to your doctor first.
  • Selank is related to a molecule that acts on the immune system: be careful with an autoimmune condition or a medication that acts on immunity.

Where the research stands

Level of evidence: Laboratory research

What is known comes mostly from laboratory research, and from clinical trials. Independent data remain limited.

Educational information, not medical advice. For your personal situation, talk to a healthcare professional.
