Effervescent tablets: know the most common

Effervescent tablets are made from the combination of a pharmaceutical active ingredient plus an organic acid and an inorganic salt.

When we deposit this pill in water, it undergoes a reaction that releases carbon dioxide, so the effect of bubbles occurs.

In general, they are recommended by doctors (as) for those who need to absorb the medicine quickly or have difficulty swallowing pills.

What are the most common effervescent remedies?

Today, the most common effervescent tablets are fruit salts, which work to combat acidity in the stomach.

But, in addition to them, it is possible to find options with analgesic and anti-inflammatory action, as well as vitamin supplements such as Vitamin C (ascorbic acid).

Learn more about some of the most common options:


Effervescent Aspirin can be indicated by a doctor for the relief of symptoms such as pain, fever and inflammation that can occur during a cold , flu , sinusitis , among other respiratory infections.

It can also be indicated by a specialist for muscle, joint, back pain, toothache and headache.

Its effect is associated with the component Acetylsalicylic acid of the class of non-steroidal anti-inflammatory drugs (simple analgesics).

The aspirin can effervescent be used by adults, 1 to 2 tablets, which can be repeated 4 to 8 hours as medical guidelines. Children over 12 years old should take only 1 effervescent tablet a day.

Another version available is Aspirin C , which contains Vitamin C in the formulation, in order to combine this important component for strengthening the body.


The effervescent Novalgine effect is quite fast, taking an average of 30 to 60 minutes to relieve pain or reduce fever. Its active ingredient is Dipyrone monohydrate.

The medication can be indicated by a specialist for adults and adolescents over 15 years.

Depending on the dosage, it can be taken up to 4 times a day, with only one effervescent tablet at a time.

Novalgina is contraindicated for pregnant and breastfeeding women, and also for those who have any health problem such as Porphyria (acute or cutaneous).

That is why we reinforce that its use should be made following medical recommendations.


Effervescent Redoxon can be indicated by health professionals for those who need vitamin C supplementation in the body.

Vitamin C is absorbed in small amounts by our body, so it is necessary to look for sources of this vitamin through food or, when prescribed, supplements.

In this way, Redoxon will act as a vitamin supplement , promoting the strengthening of immunity and defending cells from free radicals.

Also available on the market is the Redoxon Triple Action version , which in addition to Vitamin C, has Vitamin D and the mineral Zinc, providing strengthening of the organism.

Adults and children over 12 years of age should take 1 tablet daily, diluted in a glass with approximately 200mL of water.


Made with arginine aspartate, Targifor can help reduce fatigue and tiredness (asthenia).

These symptoms are caused due to the release of some toxic components, such as ammonia, during the process of generating energy by the cells.

To help improve the condition, Targifor will transform it into urea so that it is easily eliminated in the urine.

Depending on the package insert, the drug can be taken 1 tablet 2 times a day for a period of 15 or 30 days.

Another possibility for Targifor is with Vitamin C , which will help arginine aspartate to have a greater effect in combating symptoms.


The popular fruit salt Eno is an antacid indicated to relieve poor digestion and heartburn , its action occurs in less than 1 minute after use.

You can find it in the flavors of pineapple , guarana , orange , lemon , chamomile and tutti-frutti , and also in 5g sachet packs or 100g bottle .

It acts to neutralize the acids produced in the stomach, which are used for the digestion of food.

To ingest it is necessary to dissolve a maximum of 5g in 200mL of water, and should not be consumed by children under 12 years old.

Guest role

Just like the previous one, Gastrol also has the action of decreasing the discomfort in the stomach, caused by the excess of digestive acids.

This remedy can also be advised by a doctor to treat peptic ulcers, which are wounds caused on the stomach wall.

Gastrol is sold in 5g envelopes or in a carton containing 10 tablets . According to the package insert, 1 to 2 effervescent tablets should be used daily, and should not be consumed for more than 2 weeks.


Cewin is indicated for those who need to increase the amount of Vitamin C in the body, which is very important due to its antioxidant action that helps in immunity.

Vitamin C is also able to promote collagen production, making the skin firmer and healthier.

This medicine is sold in doses of 500mg , 1g or 2g for use by adults and children over 10 years. Following the dosage, 1 tablet should be taken daily.

Avoid C

Also contraindicated for children under 10 years old, Viter C can be indicated as a vitamin supplement of ascorbic acid (Vitamin C).

Vitamin C supplementation is indicated by a professional for those who cannot obtain it only with food.

The use of 1 effervescent tablet a day, in general, is already considered sufficient.


Indicated for adult use, Cenevit assists in the deficiency of Vitamin C in the body. According to the dosage, 1 tablet should be taken daily dissolved in water.

Effervescent tablets should not be taken until the entire reaction is complete, as there is a risk that you are not taking the medication completely.

That way, it is best to wait until all the bubbles, which indicate the reaction, are gone.

If you want the reaction to end faster, diluting the tablet in warm water instead of cold water can help, because, due to the temperature, the speed of this process increases.

How should effervescent tablets be taken?

Contrary to what many people think, effervescent pills should be taken only after all the bubbles are gone – that is, after the effervescence has occurred. Taking before, while it is still in reaction, may cause the compounds to not be completely effective. But it shouldn’t take too long, as the medicine can oxidize and lose its effect.

Thus, soon after the bubbles stop forming, it is already possible to ingest.

Regardless of whether it is an antacid or vitamin, it is necessary to consult the information on the packaging and a specialist to make sure that there is no contraindication, according to your clinical condition.

In general, effervescent tablets should be used:

C vitamin

Adults and children over 12 years of age should take 1 effervescent tablet, diluted in water, per day.

Care must be taken not to exceed the limit of 2000mg per day, as it can be harmful to the body, causing side effects such as:

  • Diarrhea;
  • Sickness;
  • Vomiting;
  • Headache;
  • Insomnia.

To avoid these problems, always follow the medical guidelines on the use of Vitamin C.


The dose, in general, is 20mg per day diluted in half a glass of water. Regarding the schedule, it is advised 1 hour after meals.

Depending on the purpose of the treatment, a doctor may recommend using higher doses.

We emphasize that prolonged use of antacids without a prescription can trigger malabsorption of nutrients, vitamins and minerals and even cause infections.

When is the best time to take effervescent vitamin C?

There is no specific time to take effervescent vitamin C, it depends on the dosage of each medication or supplement.

However, for better absorption, vitamin C can be taken on an empty stomach in the morning.

Effervescent tablets are quite common options for some medications, such as Vitamin C and antacids. Therefore, it is essential to know about your indications and never do self-medication .
