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

This risk is greater when high doses and prolonged treatments are used, in patients with a history of peptic ulcers, 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, corticosteroids, anticoagulants, or antidepressants (see the section "Other medicines and Dolotren Retard").
• If you have any of the following conditions: asthma, mild heart disease, liver or kidney disease, high blood pressure, bleeding disorders, or other blood disorders, including hepatic porphyria.
• If you are taking diuretic medications (which increase urine volume).

(These are listed at the end of the leaflet). The signs of a hypersensitivity reaction are swelling of the face and mouth (angioedema), breathing difficulties, chest pain, runny nose, skin rash, or any other allergic reaction.
• If you have ever had a severe skin rash or skin peeling, blisters, or ulcers in the mouth after taking Dolotren or other painkillers.

Tell your doctor:

• If you are taking medications that alter blood clotting 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 could increase the risk of such bleeding, such as corticosteroids and selective serotonin reuptake inhibitor antidepressants.
• If you have Crohn's disease or ulcerative colitis, as medications like Dolotren can worsen these conditions.
• If you have recently undergone or are going to undergo stomach or intestinal surgery before taking Dolotren, as Dolotren can sometimes worsen wound healing in the intestine after surgery.
