Special instructions

Before using Diclofenac, it is important to familiarize yourself with its instructions. It is necessary to pay attention to a number of special instructions, which include:

  1. With the simultaneous use of other nonsteroidal anti-inflammatory drugs, the dose of Diclofenac injection solution must be reduced.
  2. The active ingredient of the drug inhibits the aggregation (gluing) of platelets, so during the use of the solution for parenteral administration of Diclofenac, it is necessary to carry out laboratory monitoring of the state of the hemostatic system (blood coagulation system).
  3. During the course of treatment of the drug is not recommended to perform work requiring increased concentration or speed of psychomotor reactions.

Drug interactions

Simultaneous use with:

  • GCS or other NSAIDs - causes adverse reactions from the gastrointestinal tract;
  • cyclosporine - increases nephrotoxic effect of the latter;
  • antidiabetic drugs - may trigger hyper- or hypoglycemia;
  • methotrexate - can lead to increased concentrations and increased toxicity of the latter;
  • antihypertensive drugs and diuretics - reduces the effectiveness of these funds;
  • acetylsalicylic acid - helps to reduce the serum concentration of diclofenac;
  • potassium-sparing diuretics - leads to hyperkalemia;
  • anticoagulants - requires regular monitoring of hemocoagulation;
  • lithium preparations, phenytoin or digoxin - helps to increase the plasma concentration of these funds.

If there is evidence, eye drops can be combined with other ophthalmologic agents that include GCS (between instillations it is necessary to withstand at least a 5-minute break).

Consequences of alcohol with NSAIDs

Drinking alcohol during the period of NSAID treatment may cause:

  • development of unpredictable complications and adverse reactions;
  • deterioration of the liver;
  • reduce the effectiveness of the drug;
  • hypertension and, as a result, increased stagnation in the circulatory system and intoxication of the body.

Injections and alcohol compatibility do not have, since the injection form of the drug stimulates the activity of the central nervous system, and alcohol, by contrast, inhibits it. As a result, quite serious neurological disorders are possible.


We picked up some reviews of people about Diclofenac injections:

  1. Sergei. I have two intervertebral hernias constantly pricking diclofenac. I always hear from doctors that he is harmful, they are trying not to prescribe him. What is harmful is not explained. I tried various painkillers, and expensive ones as well. I do not know why, but only diclofenac acts on me. The price is generally ridiculous 55 rubles.
  2. Anna. Although my diclofenac was pricked in my injections, my stomach began to hurt a lot. So the most interesting thing is, then in a paid clinic they said that it wasn’t necessary to install it at all, but it was necessary to put an elbon, because it heals joints, and diclofenac just relieves inflammation.
  3. Alexander. My acquaintance with dikolfenak took place because of one unexpected incident. It was necessary to meet the niece early in the morning. He got up early, began to dress, but did not manage to pull on the second leg of his trousers, as the wildest pain pierced. Sweat rolled in hail, but somehow got dressed, his wife helped get behind the wheel, met. And in the morning in the clinic, diagnosis, osteochondrosis. They prescribed diclofinac injections, and although it is often about notorious fame, it was he who helped me on the new day at least to serve myself. Perhaps a lot of side effects, but nevertheless still with his task, he copes great.
  4. Oksana. I have long suffered from such an unpleasant disease as gonarthrosis. Exacerbations occur regularly, 2-3 times a year, especially in the wet, spring-autumn period. At this time I suffer from painful pain in the joints. During the next exacerbation, the rheumatologist prescribed Diclofenac. The drug is quite inexpensive, the pharmacy is released freely. So, I felt relief on the second day after the start of treatment. The course took only 5 days. But the doctor warned that a second course can be taken no earlier than six months, since Diclofenac can provoke a stomach ulcer with frequent use.

Most practitioners speak about Diclofenac as an effective and fast-acting medication. Meanwhile, the cardiovascular risk of diclofenac is higher than that of its other "relatives" from the NSAID group. The shorter the course of treatment, the less likely the development of negative side effects. It is extremely important to observe the recommended dosage, take into account contraindications and not resort to self-treatment without a doctor's prescription.


If for any reason the pharmacy did not have Diclofenac or the patient has contraindications, such a drug can be replaced with a similar remedy.

Analogues of diclofenac are:

  • Bioran;
  • Ibuprofen;
  • Voltaren;
  • Diklak;
  • Ortofen;
  • Diclogene;
  • Orthofer.

Before using analogues consult your doctor.

Which is better: Diclofenac or Ibuprofen?

Ibuprofen-based drugs indiscriminately inhibit COX. That is, having the same indications for use and contraindications, they provoke the same side effects.

However, unlike its counterpart, Ibuprofen is somewhat better tolerated by children and pregnant women, which makes it possible to use it (albeit with caution) in pediatrics and obstetric-gynecological practice.

Storage conditions and shelf life

The shelf life of the solution for parenteral administration of Diclofenac is 5 years. The drug must be stored out of the reach of children at an air temperature not higher than + 25 ° C.
