What are the side effects of aminophylline tablets

Aminophylline tablets are actually mainly used to treat bronchial asthma, but many patients are prone to side effects after using these drugs, with common symptoms being nausea and vomiting, loss of appetite, or stomach discomfort.

1. Adverse reactions such as nausea, vomiting, loss of appetite, stomach discomfort, anxiety, insomnia, and facial flushing may occur . Once these adverse reactions occur, the dosage should be reduced as appropriate. If symptoms such as tachycardia, arrhythmia, fever, dehydration, mental disorder, psychiatric disorder, convulsion or coma occur, the drug should be discontinued immediately and active measures should be taken for treatment.

2. Intramuscular injection may cause local pain , and adding 2% procaine injection can relieve the pain. It is now less used. Rapid intravenous injection of large doses of aminophylline may cause arrhythmias or even cardiac arrest. It is speculated that this may be related to the fact that aminophylline solution is an alkaline liquid. Therefore, the dosage must be correctly controlled and the speed of intravenous injection should not be too fast. Patients with heart disease should pay more attention.

3. Anaphylactic shock is occasionally seen, which is related to type I hypersensitivity reaction. Therefore, medical history should be routinely asked before taking the medicine. It is contraindicated for those who are allergic to this product.

4. I may be related to the product caused by urinary retention, which can increase the concentration of cAMP in smooth muscle cells and inhibit the induction of the contractile response of the detrusor muscle. Therefore, it should be used with caution in patients with prostatic hypertrophy.
