Warnings and precautions

Consult your doctor or pharmacist before starting Dolotren 50 mg:

• If you have had or develop a stomach or duodenal ulcer, hemorrhage, or perforation, which may manifest as severe or persistent abdominal pain and/or black stools, or even without previous warning symptoms.

This risk is higher when using high doses and prolonged treatment in patients with a history of peptic ulcer disease and in the elderly. In these cases, your doctor will consider the possibility of associating a stomach protector.

• If you are taking other anti-inflammatory medications, including acetylsalicylic acid/aspirin, corticosteroids, anticoagulants, or antidepressants (see the section "Other medications and Dolotren 50 mg").
• If you have any of the following conditions: asthma, mild heart disease, liver disease, kidney disease, hypertension, bleeding disorders, or other blood disorders, including porphyria hepatica.
• If you are taking diuretics (which increase urine volume).
• 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 to any of the other components of Dolotren. (They are listed at the end of the leaflet). The signs of a hypersensitivity reaction are facial and oral swelling (angioedema), breathing difficulties, chest pain, runny nose, skin rash, or any other allergic reaction.

Inform 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 mention the use of other medications that may increase the risk of these hemorrhages, such as corticosteroids and selective serotonin reuptake inhibitors.
• If you have Crohn's disease or ulcerative colitis, as Dolotren-type medications may worsen these conditions.
• If you have liver, kidney, or blood disorders, you will need to have frequent blood tests during your treatment. This will allow your doctor to control the functioning of your liver (transaminase levels), kidneys (creatinine levels), or blood (lymphocyte, erythrocyte, and platelet levels). Your doctor will then decide whether to interrupt or change your Dolotren dose.
• If you have recently undergone or are about to undergo stomach or intestinal surgery before taking Dolotren, as Dolotren may sometimes worsen the healing of intestinal wounds after surgery.
