Yes, we know how tedious that was to read.

Symptoms of Cyproheptadine Overdose

The first thing anybody would do after taking an excessive amount of anything is googling if they’re going to die or not. But fret not, you have us! Here are 7 signs that things might be awfully bad:

  1. Abdominal tenderness: your stomach becomes very sensitive to touch.
  2. Dry mouth and tongue
  3. Fast heartbeat
  4. Blurred vision/ dilated pupils
  5. Shaking and tremors (involuntary movements)
  6. Depression & anxiety
  7. Delirium: talking or behaving irrationally.

We know what some people may say “Oh boohoo what harm could it do?” Ignoring these symptoms can lead up to more severe consequences such as convulsions (seizures) which cause muscles in your body contract uncontrollably, loss of consciousness , respiratory failure etc, If left untreated it might even get worse!

How Much Is Too Much?

“It feels so great I’m gonna pop another!” Thought every irresponsible person at least once and probably got punished for their stupidity later on, again don’t worry we won’t judge you! So how much does it take for someone to unintentionally pack their bags off this earth ? Well according to the National Institutes Of Health Consuming cyproheptadine beyond prescribed medicinal level could range anywhere from mild effects at around1400–1600 mg in adults to fatal effects at approximately 10,000mg for People weighing around 68-80 Kgs.

Dosage Severity of reaction
