4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

More serious side effects

• Rarely (may affect up to 1 in 100 people), allergic reactions such as skin rash, raised and itchy patches on the skin, and severe allergic reactions with weakness, low blood pressure, difficulty breathing, and swelling of the face have been reported. If you think you are experiencing this type of reaction, you must stop the injection of Lonquex and seek medical help immediately.
• Rarely, cases of enlarged spleen and spleen rupture have been reported with other medicines similar to Lonquex. Some cases of spleen rupture were fatal. It is important that you contact your doctor immediately if you notice pain in the upper left side of the abdomen or in the left shoulder, as these symptoms may be related to a problem with the spleen.
• Cough, fever, and difficulty or pain when breathing may be signs of serious lung side effects, such as pneumonia and acute respiratory distress syndrome, which can be fatal. If you experience fever or any of these symptoms, it is important that you contact your doctor immediately.
• Contact your doctor immediately if you experience any of the following symptoms: swelling that may be associated with urinating less often, difficulty breathing, swelling, and feeling of fullness in the abdomen, and a general feeling of tiredness. These symptoms usually develop very quickly.

These may be symptoms of a condition called “capillary leak syndrome”, which causes blood to leak from small blood vessels in your body and requires urgent medical attention.
