1. What Dolotren Injectable is and what it is used for

Dolotren contains diclofenac sodium, which belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs), used to treat pain and inflammation.

This medicine is used for the symptomatic treatment of severe acute pain associated with:

• rheumatoid arthritis
• ankylosing spondylitis
• osteoarthritis
• soft tissue rheumatism
• renal colic
• acute gout attack
• lower back pain
• musculoskeletal pain
• postoperative and post-traumatic pain.

2. What you need to know before you use Dolotren Injectable

It is important that you use the smallest dose of Dolotren that relieves or controls your pain and do not use this medicine for longer than necessary to control your symptoms.

Do not use Dolotren Injectable

• if you are allergic to diclofenac or any of the other ingredients of this medicine (listed in section 6).
• if you are allergic or have had allergic reactions to acetylsalicylic acid or other similar painkillers. Reactions can include asthma (difficulty breathing), hives (allergic reaction on the skin with itching), acute rhinitis (inflammation of the nasal mucosa), or facial swelling. If you think you may be allergic, consult your doctor.
• if you have had a stomach or duodenal hemorrhage or have suffered, on two or more occasions, a perforation of the digestive tract while taking a non-steroidal anti-inflammatory drug.
• if you currently have or have had, on more than one occasion, a stomach or duodenal ulcer or hemorrhage.
• if you suffer from active Crohn's disease or ulcerative colitis (diseases that produce diarrhea with or without blood and abdominal pain).
• if you have severe kidney disease.
• if you have severe liver disease.
• if you have established heart disease and/or cerebrovascular disease, for example, if you have had a heart attack, stroke, mini-stroke (TIA), or blockages in the blood vessels of the heart or brain, or have had surgery to remove a blockage or perform a coronary bypass.
• if you have blood coagulation disorders or are being treated for them.
• if you have had problems with blood circulation (peripheral arterial disease).
• if you are in the third trimester of pregnancy.

Make sure your doctor knows before taking diclofenac:

• If you smoke
• If you have diabetes
• If you have angina, blood clots, high blood pressure, high cholesterol, or high triglycerides.

Side effects can be minimized by using the lowest effective dose for the shortest possible time.

Warnings and Precautions

Consult your doctor or pharmacist before starting to use Dolotren Injectable:

• If you have had or developed an ulcer, hemorrhage, or perforation in the stomach or duodenum, which can be manifested by intense or persistent abdominal pain and/or black stools, even without previous warning symptoms.

This risk is greater when high doses and prolonged treatments are used, in patients with a history of peptic ulcer, and in the elderly. In these cases, your doctor will consider the possibility of associating a stomach protective medication.

• If you are taking other anti-inflammatory medications, including acetylsalicylic acid/aspirin, even at low doses, corticosteroids, anticoagulants, or antidepressants, because it increases the risk of ulcer and/or gastrointestinal bleeding (see section "Other medicines and Dolotren Injectable").
• If you suffer from any of the following conditions: asthma, mild heart disease, liver or kidney disease, high blood pressure (hypertension), bleeding disorders, or other blood disorders, including hepatic porphyria.
• If you are taking medications for blood pressure or cyclosporin, because it increases the risk of kidney damage (see section "Other medicines and Dolotren Injectable").
• Some people SHOULD NOT use Dolotren. Consult your doctor if you think you may be allergic to diclofenac sodium, acetylsalicylic acid, ibuprofen, or any other NSAID, or any of the other ingredients of Dolotren (listed at the end of the leaflet). The signs of a hypersensitivity reaction are swelling of the face and mouth (angioedema), breathing problems, chest pain, runny nose, skin rash, or any other allergic reaction.
• If you have ever had a severe skin rash or peeling, blisters, or sores in the mouth after taking Dolotren or other painkillers.

Tell your doctor:

• If you are taking medications that alter blood coagulation or increase the risk of ulcers, such as oral anticoagulants or antiplatelet agents like acetylsalicylic acid. You should also discuss the use of other medications that may increase the risk of such bleeding, such as corticosteroids and selective serotonin reuptake inhibitors.
• If you have Crohn's disease or ulcerative colitis, as medications like Dolotren can worsen these conditions.
• If you have liver or kidney failure, or blood disorders, you will need to have frequent blood tests during your treatment. This will allow your doctor to monitor the functioning of your liver (transaminase levels), kidneys (creatinine levels), or blood (lymphocyte, erythrocyte, and platelet levels). With this, your doctor can decide to interrupt or change the dose of Dolotren.
• Tell your doctor if you have recently undergone or are going to undergo stomach or intestinal surgery before taking Dolotren, as Dolotren can sometimes worsen the healing of intestinal wounds after surgery.

Patients with Cardiovascular Problems

Medicines like Dolotren can be associated with a moderate increase in the risk of heart attacks (myocardial infarction) or strokes, especially when used in high doses and for prolonged treatments. Do not exceed the recommended dose or treatment duration.

If you have heart problems, a history of strokes, or think you may be at risk of having them (for example, you have high blood pressure, diabetes, high cholesterol, or are a smoker), you should discuss this treatment with your doctor or pharmacist.

Similarly, this type of medication can cause fluid retention, especially in patients with heart disease and/or high blood pressure (hypertension).

Children and Adolescents

The use of Dolotren Injectable is not recommended in children and adolescents.

Other Medicines and Dolotren Injectable

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines, including those bought without a prescription.

Certain medicines can interact with Dolotren Injectable; in these cases, it may be necessary to change the dose or interrupt treatment with one of them.

It is important that you inform your doctor if you are taking or have recently taken any of the following medicines:

• medicines containing lithium or serotonin reuptake inhibitors (for treating certain types of depression),
• medicines containing methotrexate (for treating rheumatoid arthritis and cancer),
• medicines containing cyclosporin or tacrolimus (after transplants),
• medicines containing trimethoprim (to prevent and treat urinary tract diseases),
• medicines for heart problems (digoxin, calcium antagonists such as verapamil or isradipine),
• medicines used to treat diabetes, except insulin,
• medicines for high blood pressure (diuretics, beta-blockers, and ACE inhibitors),
• medicines to prevent blood clots,
• medicines containing quinolone or ceftriaxone (for treating infections),
• corticosteroids (medicines that reduce inflammation and the action of the immune system),
• other medicines of the same group as Dolotren (NSAIDs), such as acetylsalicylic acid or ibuprofen,
• medicines containing voriconazole (a medicine used in the treatment of fungal infections),
• medicines containing phenytoin (a medicine used to treat epileptic seizures),
• medicines containing misoprostol (for treating stomach ulcers),
• medicines containing cholestyramine and colestipol (to reduce blood cholesterol levels),
• medicines containing pentazocine (for relieving pain).

As a general rule, Dolotren 75 mg Solution for Injection ampoules should not be mixed with other injectable solutions.

Using Dolotren Injectable and Alcohol

Using this medicine with alcohol consumption may increase the toxicity of Dolotren.

Pregnancy, Breastfeeding, and Fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Pregnancy

Because the administration of medicines like Dolotren has been associated with an increased risk of congenital anomalies/abortions, it is not recommended during the first and second trimester of pregnancy unless strictly necessary and as indicated by your doctor. If you need treatment during this period or while trying to become pregnant, you should take the minimum dose for the shortest possible time.

From the 20th week of pregnancy, Dolotren can cause kidney problems in your fetus if taken for more than a few days, which can lead to low levels of amniotic fluid surrounding the baby (oligohydramnios). If you need treatment for more than a few days, your doctor may recommend additional checks.

In the third trimester, the administration of Dolotren is contraindicated as it may harm your fetus or cause problems during delivery. It can cause kidney and heart problems in your fetus. It can affect your and your baby's tendency to bleed and delay or prolong labor more than expected.

Breastfeeding

Small amounts of diclofenac sodium may appear in breast milk; therefore, you should not use Dolotren Injectable during breastfeeding.

Fertility

For female patients of childbearing age, it should be noted that medicines like Dolotren have been associated with a decrease in fertility.

Driving and Using Machines

The influence of diclofenac on the ability to drive and use machines is negligible or minimal. However, patients who experience visual disturbances, vertigo, dizziness, somnolence, or other central nervous system disorders while being treated with Dolotren should avoid driving vehicles or operating machinery.

Dolotren Injectable contains propylene glycol (E-1520), sodium metabisulfite (E-223), sodium (from sodium metabisulfite (E-223), sodium hydroxide, and diclofenac sodium), and benzyl alcohol

This medicine contains 624 mg of propylene glycol in each ampoule. It can produce symptoms similar to those of alcohol and may decrease the ability to drive or operate machinery.

This medicine can cause severe allergic reactions and bronchospasm (sudden feeling of suffocation) because it contains sodium metabisulfite (E-223).

This medicine contains less than 23 mg (1 mmol) of sodium per ampoule, which is essentially "sodium-free".

This medicine contains 93.6 mg of benzyl alcohol in each ampoule. Benzyl alcohol can cause allergic reactions. It should not be administered to premature or newborn infants (up to 4 weeks of age) unless recommended by your doctor. This medicine should not be used for more than one week in children under 3 years, as it can cause toxic and allergic reactions in children under this age.

Consult your doctor if you are pregnant or breastfeeding, as large amounts of benzyl alcohol can accumulate in your body and cause adverse effects (metabolic acidosis).

3. How to use Dolotren Injectable

Follow exactly the administration instructions of this medicine indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Use in Adults

The recommended dose is 1 ampoule (75 mg of diclofenac sodium) once a day. Exceptionally, in severe cases, two daily injections can be administered, separated by several hours.

Dolotren Injectable should not be administered for more than two days. Once the acute crisis has stopped, treatment will continue with Dolotren in tablets or suppositories.

If an ampoule is combined with either of the other two pharmaceutical forms, the dosage should not exceed 150 mg/day.

The medicine will be injected intramuscularly in a deep intragluteal injection in the upper outer quadrant.

To open the ampoule, follow these instructions:

Breakable ampoule. Place your thumb below

the break line below the colored point

Use in Elderly Patients

Elderly patients may be more sensitive to the effects of Dolotren Injectable than other adults. Therefore, it is especially important that elderly patients immediately inform their doctor of any adverse reactions that occur.

If you use more Dolotren Injectable than you should

In case of overdose or accidental ingestion, consult your doctor or pharmacist, go to the emergency department of the nearest hospital, or call the Toxicology Information Service. Telephone (91) 562 04 20, indicating the medicine and the amount used. It is recommended to take the packaging and the leaflet of the medicine to the healthcare professional.
