Theophylline Side Effects
I am wondering about the side affects of the Theophylline? I have asthma, and have been suffering since thanksgiving with severe attacks. My doctor prescribed this, not sure it is helping. ## Theophylline can cause nausea, vomiting, diarrhea, increased urination, increase in heart rate, abnormal heart rhythms, restlessness, headaches, insomnia, irritability, dizziness and lightheartedness.1 REPLY Updated
