MUMMY, BEFORE YOU GIVE THAT COUGH SYRUP TOO...
Your child is vomiting, so you give Promethazine syrup.
Now, because the child is also coughing, you reach for a cough syrup and gave.
“Different problem, different medicine. No wahala.” 😌
Here is what you may need to know. 👀
Promethazine itself is an antihistamine with significant sedating effects. Some cough syrups also contain sedating antihistamines such as chlorpheniramine or diphenhydramine.
So you could end up giving:
Promethazine → sedating antihistamine
PLUS
Chlorpheniramine/Diphenhydramine → another sedating antihistamine
Different bottles.
Different names.
But overlapping effects.
😴 Then the child starts sleeping...
Mummy:
“Ah! The vomiting has stopped and this child is sleeping peacefully. God is good!” 😂
Pharmacist:
“Madam, before we start praising the sleep, let's check the bottles.” 😭
Promethazine can cause marked drowsiness, and its sedative effects can be increased when combined with other medicines that depress the central nervous system.
Some cough preparations containing chlorpheniramine also carry warnings about marked drowsiness.
⚠️ And there's an even more important warning
Promethazine should NOT be given to children under 2 years of age because of the risk of potentially fatal respiratory depression.
So please don't use promethazine simply because “it is the syrup we normally use when the child vomits.”
👀 BEFORE COMBINING CHILDREN'S SYRUPS:
Don't just ask:
“What is this medicine for?”
Also ask:
“What are the active ingredients?”
A cough syrup may contain an antihistamine.
An anti-vomiting medicine may also be an antihistamine.
Adding them together may increase unwanted effects.
And if a child becomes unusually difficult to wake, has abnormal breathing, becomes extremely drowsy, develops seizures, or loses consciousness after taking medicines, seek urgent medical attention.
MUMMIES, REMEMBER:
Different bottles don't always mean different medicines.
Before giving another syrup, check the ingredients or ask a pharmacist.
Because sometimes...
The child isn't “sleeping like a baby.”
The medicines are making the baby sleep.
Share this with a mother, father, grandmother or caregiver who keeps several children's syrups at home.
