What is the Typical Delsym Dose For Adults?
Adults and children over 12 years old typically take 10 mL (which equals 60 mg of dextromethorphan) every 12 hours. This dosing schedule provides sustained cough relief throughout the day and night. It’s important not to exceed 120 mg in a 24-hour period to avoid potential side effects such as dizziness, nausea, or more severe reactions.
Because Delsym is an extended-release formula, taking it more frequently than every 12 hours is not recommended. If cough symptoms persist beyond a week, consult a healthcare professional to rule out underlying causes.
What is the Typical Delsym Dose For Children?
Children 5 to 12 Years
For children aged 5 to 12, the recommended dose is 5 mL (30 mg) every 12 hours. As with adults, the maximum daily dose should not exceed 60 mg. This dose helps manage cough without exposing children to unnecessary risks.
Children Under 4 Years
Delsym is generally not recommended for children under 4 years old due to the risk of side effects and lack of established safety data. If a child younger than 4 has a cough, it’s best to consult a pediatrician before administering any cough suppressant.
What to Do If You Miss a Dose of Delsym?
If you miss a dose of Delsym, take it as soon as you remember, unless it’s almost time for the next dose. Do not take two doses at once to make up for the missed one, as this can increase the risk of side effects. Maintaining the 12-hour interval between doses is key to avoiding overdose.
How to Adjust Your Delsym Dose For Certain Medical Conditions
Liver or Kidney Impairment
People with liver or kidney problems should use Delsym cautiously. These conditions can affect how the body processes medication, potentially increasing side effects. It’s best to consult a healthcare provider before using Delsym if you have any chronic liver or kidney issues.
Other Medications
Delsym can interact with other drugs, especially certain antidepressants and medications that affect serotonin levels. These interactions can cause serious side effects such as serotonin syndrome. Always inform your doctor about all medications you are taking before starting Delsym.
Delsym Overdose and Warnings
Taking more than the recommended dose of Delsym can lead to symptoms such as confusion, hallucinations, difficulty breathing, and loss of consciousness. If an overdose is suspected, seek emergency medical attention immediately.
Other warnings include avoiding alcohol while taking Delsym and not using it in combination with other cough or cold products containing dextromethorphan to prevent overdose.
Tips For Taking Delsym Safely
Always measure liquid doses with the provided dosing cup or syringe to ensure accuracy.
Do not exceed the recommended dose or frequency.
Keep Delsym out of reach of children to prevent accidental ingestion.
