Do Kalms contain antihistamine?

In this guide, we will discuss ‘Do Kalms contain antihistamine’, who should not use antihistamines, Kalms night ingredients, what are Kalms tablets, types of Kalms, and additional considerations when using Kalms. 

Do Kalms contain antihistamine?

Kalms doesn’t seem to contain antihistamines and the reason being is that this herbal medicine is based on Valerian root, which possesses sedative and anxiolytic properties.

According to Ismail, (2012) “Valerian is thought to work by binding to gamma-aminobutyric acid (GABA) type I receptors to improve responses to the neurotransmitter GABA.”

However, the efficacy and properties of valerian as a sleeping aid hasn’t been established entirely.

It seems to improve sleep by reducing the time someone takes to fall asleep but just from a subjective point of view.

On the other hand, antihistamines (diphenhydramine) are widely known for the treatment of allergies and due to their sedating effect, it has been used as an over the counter medication of mild insomnia.

However, it is not recommended to take antihistamines as a long-term treatment for insomnia since in the short term, the body is able to develop tolerance to their effect.

Moreover, valerian has been found fairly safe with minimal side effects but antihistamine’s effect is said to carry over into the next morning and can include several side effects (Ismail, 2012).

One of the most famous sleeping aids that contain diphenhydramine is Nytol, but do not mistake it with Nytol Herbal tablets which actually are antihistamine-free.

What if I can’t sleep?

You may be familiar with the feeling of being fatigued or drowsy during the day, or maybe even both.

If so, you may have turned to your morning caffeine fix to be able to cope with the day ahead.

The lack of sleep can be responsible for being irritable, memory problems, or difficulties recalling information.

You may have been diagnosed with insomnia or you may suspect you have it. Let’s see some of the symptoms:


•    Difficulty falling asleep

•    Waking up often during the night and having trouble getting back to sleep

•    Waking up too early in the morning

•    Feeling tired upon waking

In addition, you may be looking for all the options available to you to treat insomnia.

You may have heard about how herbal remedies such as Kalms, passionflower, Nytol Herbal or hop strobiles are used as sleeping aids.

However, you may have also been considering antihistamines found in over the counter medication such as Nytol.

Our recommendation is to be careful and if you are really suffering from insomnia or you suspect, talk to your physician to study the options that may fit you. 

Who should not use Antihistamines?

Even though Kalms does not contain antihistamines, we can inform you that they have many restrictions in terms of who can actually use it if you are considering it.

According to the NHS consult with your doctor before taking antihistamines if you have any of the following:

  • Asthma or COPD, or illness that created a lot of phlegm.
  • Primary angle-closure glaucoma.
  • A stomach ulcer or a blockage in your stomach or kidney.
  • Kidney or liver problems. 
  • Problems peeing of emptying your bladder. 
  • Epilepsy or any other problem that may cause fits.
  • Intolerance to, or cannot absorb, some sugars such as lactose or sorbitol.

Why is this blog about Do Kalms contain antihistamine important?

As we have discussed already, Kalms does not contain antihistamines. It is regarded as a safe herbal remedy that helps relieve mild symptoms of anxiety, stress, periods of irritability, and even as a sleeping aid.

However, we have seen how antihistamines found in OTC such as Nytol can only be used for short periods of time and also shouldn’t be used by people with certain conditions since it can become dangerous for their health.

Always consult with your doctor before taking any medicine even if it is classed as an herbal remedy since not everyone reacts the same to it.
