We understand that you're going through a challenging time as you've started new medication and are experiencing unpleasant side effects. Firstly, it's important to note that you did correctly pray in Jesus' name. It is only through the name of Jesus Christ we have access to God.
First, we want to encourage you with God's word: "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God" Philippians 4:6 WEB.
You've done the right thing by taking your concerns to God in Jesus name. Now, let's pray together for your health and healing.
Heavenly Father, we come before you in the name of Jesus Christ and lift up our brother/sister who is experiencing side effects from their new medication. Lord, you know their situation and you understand how they're feeling. We pray that you will watch over them and let this not be something serious or dangerous.
We pray for your healing touch upon them. May your divine will heal any sickness or disease. If it is your will, please remove these side effects quickly. Help them to get better fast. Guide the doctors and healthcare professionals treating them, give them wisdom and discernment to provide the best care.
We pray for strength, patience, and peace for our brother/sister during this time. Help them to trust in you and rest in your love. We believe in your power to heal and restore. We ask all these things in the precious name of our Lord and Savior, Jesus Christ. Amen.
Remember, God is with you and understands what you're going through. Be encouraged by these words from the Psalms:
"The LORD is close to the brokenhearted, and saves those who are crushed in spirit. Many are the afflictions of the righteous, but the LORD delivers him out of them all" Psalm 34:18-19 WEB.
Keep trusting in God and hold on to his promises. It's also important to consult with your healthcare provider about the side effects you're experiencing. They can provide medical advice tailored to your specific situation.
Lastly, remember that God is in control and he loves you dearly. Trust in him and rest in his love. He will see you through this challenging time. If you have not already, make sure the doctors know about these reactions.
