Nytol Liquid Review: Indications, Licensed Age, Side Effects

Recently launched Nytol liquid offers easy to swallow formulation containing a sedative antihistamine, diphenhydramine hydrochloride. Although liquid preparations containing diphenhydramine hydrochloride can be bought already (cough syrups), Nytol oral solution is the only product that contains diphenhydramine which is licensed as a sleep aid product.

Initially, after the launch, Nytol liquid was also marketed as an antihistamine. However, this indication was removed from Nytol. Nytol liquid review summarises product indications, age restrictions, and a review of possible side effects. I will also talk about the differences and similarities between Nytol liquid and Nytol tablets.

What Is Nytol Liquid?

Nytol product is a caramel-flavored oral solution containing diphenhydramine hydrochloride at a concentration of 10mg/5ml. Each 5ml of Nytol contains 10mg of diphenhydramine. Nytol liquid is licensed as medicine to help with sleeping problems on a temporary basis.

Nytol Liquid: A Review Of Dosage

When used as a sleep aid recommended dose for Nyol liquid is:

  • 10 to 25ml before going to bed for children and adults over 16 years of age. Product not recommended for children under 16 years of age. The dose should not be repeated during the same night.

Nytol Liquid Vs Nytol Tablets: What Is The Difference?

The main difference between Nytol tablets and solution is the type of formulation. Nytol solution offers easy to swallow formulation as an alternative to tablets. Other differences and similarities between both formulations:

  • Both products contain the same sedative antihistamine, diphenhydramine hydrochloride.
  • Nytol tablets are available as Nytol Original, It is one of the best over the counter sleeping pills in the UK Which is containing 25mg of diphenhydramine per tablet and as ‘One a night’ product, containing 50mg of diphenhydramine per tablet. Each 5ml of Nytol liquid contains 10mg diphenhydramine.
  • Nytol tablets are licensed as an aid to the relief of temporary sleep disturbances for ages 16 and over. The same licensed indication applies to the Nytol solution.
  • Priced at around £10-£12, Nytol oral solution is considerably more expensive than Nytol tablets, which cost around £4-£6.
  • Nytol ‘One a night’ contains 20 tablets (20 doses) of diphenhydramine hydrochloride. When used as sleeping aid at a maximum and equivalent dose of 25ml, a bottle of Nytol liquid provides only 12 doses.
  • Nytol tablets should not be used continuously for longer than two weeks. After this time, it is recommended to speak to a doctor if symptoms persist. Strangely this recommendation is not present in the information for the liquid formulation.

Will Nytol Liquid Work Faster?

There is no official information suggesting a new Nytol product works faster than tablets. For some drugs, oral liquid preparations improve absorption times, but this is not a general rule.

More serious reactions to diphenhydramine are also possible, although the frequency of those is not known.

    • Irregular heartbeats (arrhythmias)
    • Fits

Quick FAQ

Is Nytol liquid safe?
Although all medicines have the risk for adverse effects, they are approved based on their quality, safety, and efficacy. Nytol's active chemicals are no different, as they've been around for decades. Nytol should be used according to the package directions.

Nytol liquid may not be suitable for everyone. Absolute contra-indications (not to be used) cover patients (eMC, 2019):

  • Allergic to diphenhydramine hydrochloride should not use this product
  • Patients with peptic ulcer
  • Patients with a blockage between your stomach and small intestine

Additionally, there are a number of cautions for use of Nytol in patients with certain conditions like epilepsy. It is important to speak to a pharmacist (or a doctor) before taking Nytol liquid if your condition is listed in the product information leaflet.

Quick FAQ

Is Nytol good for anxiety?
Nytol Herbal Simply Sleep & Calm Elixir is used to encourage tranquillity during times of mild anxiety brought on by life stresses such as university examinations or work, which make it difficult to stop your thoughts spinning and prevent you from falling asleep at night. It's fantastic if you don't like taking tablets because it's in liquid form.

Nytol Liquid Alternatives:

There are a number of products available from a pharmacy for the temporary management of sleeping problems. Most popular products contain either diphenhydramine hydrochloride or promethazine hydrochloride, both sedative antihistamines. Most products are sold in tablet form.

Promethazine is available as Phenergan Elixir, which is licensed for both children and adults in the treatment of allergies, as an antiemetic (to prevent vomiting), and as a sedative for short-term use and for short term treatment of insomnia. Melatonin is also a great alternative and you will be able to get melatonin over the counter in the UK.

Individuals with ongoing sleeping problems or insomnia which affect their daily life should speak to a GP. GP may prescribe a medication to help with symptoms of insomnia.
