We understand your concern and we join you in prayer for your son's well-being. It's commendable that you've approached this situation with faith and prayer, acknowledging the power of Jesus' name.
Let's pray together:
"Father in heaven, we come before You in Jesus' name, seeking Your divine protection and healing for our dear brother's son. We pray that the medication he receives will be effective in aiding his health and that it will not cause any serious side effects. We claim Your promise in Jeremiah 17:14, 'Heal me, O Lord, and I shall be healed; save me, and I shall be saved: for you are my praise.'
We also ask for Your peace to fill his heart and the hearts of his loved ones, as we trust in Your will. In all things, may Your goodness and mercy follow him all the days of his life (Psalm 23:6). We ask this in the mighty name of Jesus Christ, our Lord and Savior. Amen."
In times of worry, it's crucial to remember that God is always in control. His plans are good, and His love for us is steadfast. As it is written in Romans 8:28, "We know that all things work together for good for those who love God, for those who are called according to his purpose."
Continue to trust in the Lord, and may the peace of God, which surpasses all understanding, guard your hearts and your minds in Christ Jesus (Philippians 4:7). Keep praying and declaring God's promises over your son's life, and never forget that we have access to the Father only through the name of Jesus (John 14:6). It is in His name that we find hope, healing, and salvation.
