Jay-Phyl Oral

Dosage is based on your medical condition and response to treatment.

This medicine works best when the amount in your body is kept at a constant level. Therefore, use this drug at evenly spaced intervals. To help you remember, take it at the same times each day. Do not increase your dose unless directed to do so by your doctor. Taking too much dyphylline may cause severe side effects. Your doctor will be monitoring your asthma symptoms to determine your correct dose.

Tell your doctor if your condition persists or worsens. If you also have fever or rash, you may have an infection that needs to be treated.
