Starting Medication: What to Expect in the First Few Weeks


Reviewed by Michelle Widdows, MSN, PMHNP-C, Psychiatric Mental Health Nurse Practitioner Starting psychiatric medication for your child can be a journey filled with mixed emotions, ranging from hope to concern, and often followed by many questions. You're not alone in feeling this way. The first few weeks are a crucial stage in your child's mental health journey, and understanding what to expect can alleviate some anxiety. The goal of medication may vary—whether it's to address depression, manage anxiety disorders, or aid in emotional regulation. Regardless of the objective, starting medication requires careful attention, patience, and effective communication. 

Medications and Brain Chemistry

Most psychiatric medications for children, such as selective serotonin reuptake inhibitors (SSRIs), work by enhancing the levels of certain neurotransmitters in the brain. SSRIs are commonly used for treating anxiety and depression as they help regulate mood by increasing serotonin levels. However, these medications don’t deliver immediate results. It can take several weeks before you notice their full effects. Therefore, closely monitoring your child's feelings, behaviors, and daily reactions during this period is essential.

Initial Weeks: What to Expect

The initial phase of treatment can often feel like a waiting game. While some children may notice subtle changes in their sleep or energy levels immediately, others might not feel any difference right away. Typical early experiences include: - Slight fluctuations in appetite or sleep - Minor mood changes - Increased sensitivity or irritability - Physical symptoms like dry mouth, headaches, or stomach discomfort These side effects are usually temporary as the body adjusts, but any new symptoms should be discussed with your healthcare provider. If your child is taking stimulant medications for attention issues or ADHD, you may observe changes more swiftly—sometimes within hours or days.

Monitoring Side Effects

While severe side effects are uncommon, it is vital to be aware of them, especially when starting an SSRI or antidepressant. Occasionally, children and teens may experience heightened agitation or even thoughts of self-harm. Although the risk is minimal, regular check-ins during the first few weeks are critical. If your child shows signs of hopelessness, panic, or unexpected behavioral changes, reach out to your doctor without delay. If urgent help is required, contact a local healthcare provider or crisis support team.

Timeline for Effectiveness

The effectiveness of the medication largely depends on its type. For SSRIs and other anxiety or depression medications, you may notice improvements in symptoms within 2 to 6 weeks, with full effectiveness taking 6 to 8 weeks or longer. On the other hand, stimulant medications act more quickly, often requiring dose adjustments based on feedback.

Consistency is Key

For medications to work effectively, they must be taken consistently and as prescribed. Missing doses or stopping abruptly can lead to withdrawal symptoms or a resurgence of troubling behaviors and emotions. If a dose is missed, consult your doctor for the best course of action—never double up without medical guidance. Keep your provider informed if your child has other health conditions, as these may affect the medication plan.

Supporting Your Child

Your support is incredibly important during this adjustment phase. Check in daily about your child's emotional and social well-being, not just their symptoms. Normalize the use of medication by comparing it to other tools for health, such as glasses for vision or inhalers for asthma. Encourage healthy routines, adequate rest, regular physical activity, and quality interactions with friends. Remember that medication is a helpful tool, not a sole solution—it works best alongside healthy habits and often benefits from therapy.

Reassessing Treatment

After several weeks, it’s essential to meet with your provider to evaluate the medication's effectiveness. Discuss whether target symptoms have improved, whether side effects are manageable, and if there are observable changes in your child's school performance or mood. If the medication isn't yielding the desired results, it may be time to consider alternative strategies. Changing the treatment approach doesn't indicate failure; rather, it may be what your child's brain needs.

Long-Term Considerations

Many parents have concerns about the long-term use of medication. The answer varies: while some children may require medication for a limited time to stabilize their symptoms, others may need prolonged support. Ultimately, the focus should be on how your child is functioning in various areas of life—academic performance, home life, and social interactions. Medication decisions should continuously evolve based on your child's growth, underscored by consistent evaluations and open communication.
