Common side effects of guanfacine extended-release tablets are mainly drowsiness,headache,and decreased appetite,most of which are related to the dose adjustment period.Scientific management can improve medication compliance.

1.Drowsiness:Adjust Timing and Activity Arrangements

1.Adjustment of medication timing

If daytime drowsiness is obvious,discuss with the doctor the possibility of changing medication to bedtime to reduce daytime sleepiness.

Fix the medication time to avoid fluctuations in blood drug concentrations caused by frequent changes.

2.Daily activity arrangements

During the initial dose escalation period,avoid driving,operating machinery,or working at heights.

Schedule important tasks during periods when mental status is better,and arrange appropriate short rest periods.

3.Observation and medical visits

If drowsiness continues to worsen or is accompanied by dizziness or slowed heart rate,return for follow-up promptly to evaluate the dose.

Do not increase the dose on your own or stop the medication suddenly to avoid blood pressure rebound.

2.Headache:Identify Triggers and Provide Symptomatic Treatment

1.Common triggers

Rapid dose escalation,taking a supplementary dose after a missed dose,or blood pressure fluctuations can all trigger headache.

Dehydration,insufficient sleep,or emotional stress can worsen symptoms.

2.Relief measures

Ensure adequate water intake and regular sleep,and avoid excessive fatigue.

Mild headache can be observed with rest;if necessary,use symptomatic analgesics under the doctor's guidance.

3.Situations requiring vigilance

If the headache is severe,accompanied by blurred vision,vomiting,or obvious blood pressure abnormalities,seek medical attention immediately.

Recurrent headache requires a follow-up visit for the doctor to assess whether to adjust the dose or investigate other causes.

3.Decreased Appetite:Small Frequent Meals and Nutritional Support

1.Eating strategies

Use small,frequent meals to avoid bloating or aversion caused by eating too much at one time.

Choose high-protein,high-calorie,and easily digestible foods,such as eggs,fish,and soy products.

2.Weight monitoring

Weigh regularly and keep records,and pay attention to children's growth curves.

If weight decreases significantly or appetite loss persists,inform the doctor to evaluate the dose.

3.Lifestyle cooperation

Keep the dining environment relaxed,and avoid eating while playing or forcing the patient to eat.

If necessary,supplement nutritional preparations under the doctor's guidance to ensure energy intake.

4.Medication observation

Decreased appetite mostly occurs in the early stage of dose escalation and may lessen with prolonged medication use.

If it persists without relief or affects growth and development,return for follow-up promptly to adjust the regimen.
