Why is water for injection needed?

Where is the expiration date indicated?

Not all places in the house are suitable for storing Paracetamol. It is not recommended to store the medicine:

  • In the bathroom, because... increased humidity.
  • In the immediate vicinity of heating devices, because the temperature regime is disrupted.
  • In the kitchen cabinet in close proximity to the sink, stove and hood, because... In these places there is high humidity, there is a possibility of heating or contamination of the packaging.
  • On the windowsill, because the drug is exposed to direct sunlight, this may cause the medicine to heat up.

The use of expired medications can lead to severe poisoning, dysfunction of the liver, kidneys and other serious pathological conditions.

The drug can be freely stored at home. A shelf in a closet, a refrigerator, or a special container with a lid is suitable for this. The home first aid kit should be located out of the reach of children. Even if a suspension has not been prepared from the powder, but the packaging has already been opened, such powder can be stored for no more than a month.

How to properly store medications

A medicine is a complex multicomponent system consisting of an active substance and excipients, including preservatives, dyes, sweeteners, and binding components. The safety of the pharmacological properties regulated by the manufacturer directly depends on compliance with certain conditions for each of the ingredients, and the drug itself as a whole. As a result, the effectiveness of the drug depends on several factors:


Information on recommended temperature values ​​is contained in the instructions included with each drug. Even a slight temperature fluctuation can be detrimental to the components of the medication. For example, alcohol extracts and tinctures quickly become unusable at high temperatures, as the preservative that prevents the decomposition of substances is destroyed.

Sometimes a change in the state of the product can be noticed visually in the form of crystallization, cloudiness, or the appearance of flakes, in which case you can stop using it. But when chemical metamorphoses occur at the molecular level, that is, unnoticed by humans, this can lead to disastrous consequences.

Most solid and gaseous products packaged in aerosols are recommended to be stored at a temperature of 15-25 ˚C.

The inscription “in a cool place” means that the product must be placed in the refrigerator, since only there the temperature is maintained at up to 15 ° C. The recommendation “store at a temperature not exceeding 5 °C” should be interpreted as a requirement to put the medicine in the refrigerator.

These groups of drugs must be placed on different shelves:

  • medicines in the form of candles are placed near the freezer;
  • on the middle shelves of the refrigerator you can place tubes of ointments, gels and patches;
  • For medications whose label indicates that they need to be stored in a cool place, you need to allocate space on shelves not adjacent to the freezer or on the refrigerator door, where a consistently cool temperature is maintained (10-15 ˚C).

To protect medications sent for storage in the refrigerator from moisture, it is recommended to additionally pack them in plastic bags or a hermetically sealed plastic storage container.

Medicines must not be frozen! After defrosting, irreversible chemical reactions occur in the active substance, the course of which even an experienced pharmacist cannot predict.


All medicines are afraid of sunlight. Ultraviolet light is a catalyst for chemical and physical processes in medicines of various forms of release. It is impossible to recognize the “spoilage” of a medicine in time, so the medicines should be stored exclusively in a dark place (in a cabinet with a closing door) and away from heating appliances:

  • syrups, tinctures, etc. are stored in the original cardboard packaging - this will provide “double protection” from light;
  • It is recommended that tablets packaged in blisters should not be removed from the cardboard container, but stored in the same form as purchased at the pharmacy. As you use the medicine, you do not need to cut off the empty cells, since then the expiration date will be unknown.


Most medications in the form of tablets, capsules, and powders are hygroscopic, that is, they easily absorb moisture, which changes their pharmacological properties. Therefore, you need to know where you can safely store your medications. It is not recommended to keep medications in the bathroom, even when placing medications in a special storage box, due to high humidity.

Air access

If the seal of the original packaging is broken, the active component of the drug may evaporate, oxidize, or interact with other chemicals. As a result, the effectiveness of the drug is reduced, and the effect of taking the medicine may be exactly the opposite of the expected result. Medicines should be stored in sealed containers and, after opening, used in accordance with the above standards.

Elderly people should not be allowed to squeeze out medicine purchased in a blister from its original cells, and then pour them into a common pile in an empty bottle. This storage method can lead to oxidation of the drug or a change in its properties due to contamination (tablets are taken with hands that contain bacteria).

Injection solutions that cannot be stored after destruction of the ampoule are used by many in this way: the medicine is kept in a syringe and used gradually, and the portion prescribed by the doctor is administered every day, and a cap is put on the syringe with the remaining drug. Although you can save a little on purchasing injections, you cannot store the product in a syringe for a long time.

It is not recommended to store medicine in a syringe

Possible consequences of using expired medicine

The lifespan of an opened bottle is significantly reduced. Opened syrup can be stored for 28 days. An opened bottle of powder for preparing a suspension, even with an unprepared suspension, can be stored for 1 month.

These rules apply subject to the rules for storing the drug and in the case when the original packaging in which paracetamol and products based on it are produced is not broken.

5 ml of suspension contains 120 mg of paracetamol. In one bottle the number of 5 ml doses is: 100 g - 16 doses, 150 g - 24 doses and 200 g - 32 doses.

Turn the bottle upside down and gently pull the plunger down, drawing the suspension into the measuring syringe to the desired level. In adults, glucuronidation predominates, in newborns (including premature babies) and small children - sulfation. Conjugated metabolites of paracetamol (glucuronides, sulfates and conjugates with glutathione) have low pharmacological (including toxic) activity.

When can the drug be stored for a long time?

Ceftriaxone in solution is prescribed not only for injection, it is also used to treat mucous membranes and skin in the following cases:

  • irrigation of the oropharynx for ENT infections and gum diseases caused by bacterial microflora;
  • treatment of skin or wounds when suppuration appears.

In these cases, it is impossible to use up the prepared solution immediately, so it is allowed to store Ceftriaxone in diluted form for 24 hours. A slight destruction of the active substances of the drug will not affect the effectiveness of the drug.

The shelf life of Ceftriaxone in diluted form for injection should not exceed 6 hours at room temperature and 12 in the refrigerator. The solution prepared for treating the skin or mucous membranes can be stored for a day and a change in color (becomes yellow-orange) does not indicate that the medicine has lost its effectiveness. But it should be remembered that Ceftriaxone has a maximum therapeutic effect within an hour, and then, during storage, the activity of the active substances decreases: it is recommended not to store the prepared solution for a long time, but to prepare it before use.

Nosological classification (ICD-10)

The opened bottle can be stored with the cap screwed on at room temperature under normal conditions, or in the refrigerator. This will not affect the shelf life. What conditions is Paracetamol “afraid of”? The shelf life of suppositories and suspensions is 2 years, and storage conditions are almost the same as for paracetamol tablets.

We always take Erespal for coughs, it can be stored open until it expires, and there is also our analogue Inspiron, so it can only be stored for 30 days after opening... BUT!

Further in the article we will talk about Paracetamol syrup for children. From the instructions it is known that it has a viscous consistency, a gray or yellow tint and a strawberry aroma.

Paracetamol is a medicine used primarily to reduce fever. And also to relieve symptoms, for example, relieve headaches.

Can it be stored diluted?

The peculiarities of Ceftriaxone and other antibacterial drugs of the cephalosporin and penicillin series are such that before administering the drugs, they must be mixed with physiological sodium chloride solution or an anesthetic.

After dilution of the drug, the following occurs:

  • When interacting with the solution, the active components in the powder transform into an active form;
  • Maximum activity lasts for about an hour, and then the active substances in the solution begin to disintegrate into inactive elements.

At room temperature, after only 6 hours of storing the diluted powder, the effectiveness of the solution is reduced by almost half.

Sometimes patients who are undergoing treatment at home are interested in whether the drug will retain its effectiveness if it is stored diluted in the refrigerator with a frequency of Ceftriaxone injections twice a day.

Indeed, lowering the temperature slows down the disintegration of the active substances, but injections are given at intervals of 12 hours and if stored for a long time, Ceftriaxone will still reduce its effectiveness. If the doctor prescribes Ceftriaxone injections twice a day, then this should be done, diluting the next portion of the drug immediately before administration.

Instructions for use Paracetamol suspension for children

The expiration date is indicated on the bottle itself; the suspension is stored for a maximum of 3 years; an open bottle of medicine is stored for the same amount of time. does not deteriorate if you follow storage rules. When used together with barbiturates, tricyclic antidepressants, alcohol, anticonvulsants (phenytoin), phenylbutazone, rifampicin, the risk of developing the hepatotoxic effect of paracetamol significantly increases.

Orally, adults - 200–500 mg 2–3 times a day; children 6-12 months - 25-50 mg 2-3 times a day, up to 5 years - 100-150 mg, up to 12 years - 150-250 mg 2-3 times a day.

The therapeutic properties of the drug lie in its effect on thermoregulation centers and pain centers, resulting in an increase in the threshold of sensitivity to pain. The drug has high absorption and reaches its maximum concentration in plasma after two hours.

I don't think I found this kind of information anywhere on the forum. The question is that the pig was given injections (ketonal, dexamethasone), but the dose, of course, is very small. Is it possible to take the remains from the ampoule, for example, into a syringe and put it in the refrigerator? If so, how many days can everything be stored like this (a day, two)? And is it possible to use one syringe at least twice? Or should everything be thrown away - including the ampoule with a bunch of medicine and the syringe? The instructions for the medications don't say anything. Thanks in advance for your advice.

I’m currently injecting Ketonal and Dexamethasone. Both the pharmacy and the doctor assured me that it was impossible to store the opened ampoule. Every time I open a new one. And I use new syringes; the pharmacy did not recommend it for the second time (with a non-removable needle).

Syringes definitely cannot be used a second time. But in the clinic where I was practicing, the remaining medicine was drawn into a sterile syringe, i.e. out of the package and stored in the refrigerator for about 3-4 days. And the owners were allowed to do so. None of the patients complained and the effect of the treatment was the same as that of treatment with drugs from the new ampoules.

The ampoule definitely cannot be stored open. It is correct to do everything disposable. Of course, it is drawn into a sterile syringe, in theory it can be in the refrigerator, but I would not, since there are syringes of different quality. Hiruda, there is a difference in how they work in practice and what the basic rules are. In practice, they are sometimes abused. P.s. I am a former medical worker.

In my opinion, giving advice on storage is a big responsibility, especially the strange period of 3-4 days, so 3 or 4? and what is the temperature in the refrigerator? And I also wanted to ask, I was just interested, “none of the patients complained,” if the patient is a rodent, is it really possible to recognize what he is complaining about. Please tell us how, well, if he is, for example, a guinea pig (this is a simple case, it still makes a lot of different sounds), or if it is a rabbit (a complex case, there are few sounds).

As for the syringe, Alshinetsky said that you can use one syringe twice, but then the needle simply becomes dull. But syringes are not as expensive as medicines. Regarding the leftovers. We are not talking about an ampoule, but about storage in a syringe. The refrigerator has a special compartment for storing medicines (a closed drawer in the door). I called White Fang, they also advised me to put it into a syringe and into the refrigerator. I think that, of course, it won’t last a week, but two days is enough. Similar advice was given at the pharmacy, where the seller injected Ketonal into the dog and also kept the leftovers in the refrigerator. After all, for example, ketonal should be injected into pork twice a day. Is it really impossible to keep the medicine in the syringe at least until the evening? It’s just that maybe pig breeders themselves have their own experience on this issue?

  • Hypersensitivity to components;
  • Kidney or liver failure;
  • In complex treatment along with other medications that contain a similar active substance;
  • Lack of glucose in the blood;
  • Pathologies of the organs of the hematopoietic system;
  • Children under three months of age.

The top line displays the batch of the medicinal product, and below, in the “best before” column, the expiration date is displayed. On currency packaging (paper matrix), the series and expiration date are marked on the back side.

The separation of this ring from the lid confirms the fact that the package has been opened with all the ensuing consequences.

An overdose of paracetamol can cause liver failure, which may lead to the need for a liver transplant or death. In addition, acute pancreatitis is observed, accompanied by liver dysfunction and hepatotoxicity.

Does paracetamol have an expiration date and how should it be stored correctly?

If you need to extend the course of treatment longer than recommended, be sure to consult your doctor!

After opening the package, it is better to put the syrup and suspension on the refrigerator door. The temperature there is slightly higher than in the main chamber. The same conditions are suitable for suppositories whose storage temperature is +8°C - +15°C.

Paracetamol syrup for children and Paracetamol suspension are forms of the drug created specifically for the youngest patients. The liquid viscous consistency is very convenient for babies to take.

The medicine should be kept in a cool place, away from sunlight. This requires moderate air humidity.

Can I use expired?

Attention: sometimes people forget to check whether the medicine is still valid and take it; you should not immediately panic, especially if the medicine is only a few days or weeks out of date. Of course, it should be thrown away immediately, since if you regularly take a drug whose period of action has expired, then in addition to the appearance of side effects, the general condition of the patient worsens.

Paracetamol, just like any other drug, should be used only for a strictly permitted period of time, in this way negative effects on the human body can be avoided. It should also be remembered that if there are small children in the house, the product should be stored out of their reach.

Using expired or unsuitable medicine can cause serious harm to health. The risk of developing allergic reactions increases significantly. An allergy to Paracetamol manifests itself in the form of skin manifestations, rash, itching, Quincke's edema or anaphylactic shock.

Important! Bottles of syrup and suspension have a first-opening control ring. The separated ring from the screw cap is a fact confirming the opening of the drug.

Storage conditions and expiration dates

Details about the dosage and features of taking Paracetamol in the form of syrup and suspension can be read in the attached instructions for use (instructions for syrup and suspension). It describes dosages depending on age. But a more significant point is the patient’s weight.

The same period of time is the guaranteed shelf life of the drug, provided there is no damage to the manufacturer’s packaging. If symptoms of overdose occur, immediately stop taking the drug and consult a doctor.
