promethazine VC

Promethazine in Promethazine VC can cause dangerously slow breathing, which can be life-threatening. The risk is higher in children, people with breathing problems (e.g., chronic obstructive pulmonary disease (COPD), sleep apnea, asthma), and people taking other medications that can affect breathing (e.g., opioids, sleep medications, benzodiazepines). Use the lowest possible dose of Promethazine VC (promethazine / phenylephrine) for the shortest amount of time. Tell your prescriber about all of your medications and medical conditions to make sure Promethazine VC (promethazine / phenylephrine) is a safe option.

Medications containing promethazine shouldn't be given to children under 2 years old because of the serious risk for dangerously slowed breathing. If you're giving Promethazine VC (promethazine / phenylephrine) to a child older than 2 years old, you also need to be careful and watch out for slowed breathing. In addition, taking Promethazine VC (promethazine / phenylephrine) can put a child at risk for other serious side effects, such as seizures and hallucination, especially in children who are sick or dehydrated. Get medical help right away if you notice your child having difficulty breathing or experiencing other side effects after taking Promethazine VC (promethazine / phenylephrine).

Promethazine in Promethazine VC can cause extreme sleepiness and lower your ability to think, react, and focus. Your risk is higher if you're taking other medications that can make you sleepy, such as benzodiazepines, muscle relaxants, and sleep medications. Make sure you know how this medication affects you before driving a car or doing activities that require your concentration. Talk to your prescriber right away if you feel too sleepy from taking Promethazine VC (promethazine / phenylephrine).

The promethazine in Promethazine VC can raise the risk of seizures. The risk is higher for people who've had seizures in the past or for those who take medications that lower the seizure threshold. Let your HCP know if you have seizures more often while taking Promethazine VC (promethazine / phenylephrine).

The promethazine in Promethazine VC can cause a rare, but life-threatening condition called neuroleptic malignant syndrome (NMS). Symptoms include fever, sweating, stiff muscles, confusion, not aware of your surroundings, and fast or irregular heartbeat. If you experience any of these symptoms while taking Promethazine VC (promethazine / phenylephrine), seek medication attention as soon as possible. You HCP will likely have you stop taking Promethazine VC (promethazine / phenylephrine) and switch you to something else.

The promethazine in Promethazine VC can cause involuntary muscle movements, such as eye-twitching or lip-smacking. The risk is higher for people who are dehydrated. If you experience any uncontrolled movements and aren't able to stop them, talk to your HCP right away.

Though not common, promethazine in Promethazine VC can lower your white blood cell counts, especially if they've been low previously from other conditions. This can raise your risk of serious infection. If you develop any signs of infection, such as fever, tiredness, chills, cough, or trouble breathing, and they don't go away, contact your prescriber right away.

Phenylephrine in Promethazine VC can raise your heart rate and blood pressure, even at recommended doses. If you have a history of heart conditions or high blood pressure, ask your HCP if Promethazine VC (promethazine / phenylephrine) is safe for you before taking it. If you get severe headaches, nosebleeds, difficulty breathing, irregular heartbeat, or chest pain while taking Promethazine VC (promethazine / phenylephrine), stop the medication and seek medical attention right away.
