Frequently asked questions

What is Herpex Syrup used for?

Herpex Syrup is used to treat the symptoms of the common cold and flu, such as a runny nose, cough, sneezing, and watery eyes. It is also one of the commonly used medicines in chickenpox for symptomatic relief.

Will Herpex Syrup make me drowsy?

Promethazine, present in Herpex Syrup, causes significant drowsiness and sleepiness. Because of this, it is an excellent choice for nighttime relief of cold and flu symptoms, as it can help you get the rest you need to recover. You should not drive or operate heavy machinery after taking it.

How quickly will Herpex Syrup start to work?

You can expect to feel relief from pain and fever within about 30 to 60 minutes of taking Herpex Syrup. The sedating effects of this medicine will typically begin within about 20 minutes and reach their peak in a couple of hours, helping you to fall asleep.

Can I use Herpex Syrup for motion sickness or nausea?

Herpex Syrup can be used to prevent and treat nausea and vomiting, including motion sickness. It can also be helpful if your nausea is accompanied by a headache or general discomfort. However, it is advised to consult a doctor for the proper dose and duration for safer and desired results.

What should I tell my doctor before I start taking Herpex Syrup?

Before starting Herpex Syrup, you should inform your doctor if you have a history of breathing problems (like asthma or COPD), glaucoma, or difficulty urinating due to an enlarged prostate. This medicine can sometimes make these conditions worse, so your doctor will need to determine if it is safe for you.

Can Herpex Syrup be used to treat a cough?

While Herpex Syrup is not a primary cough suppressant, the antihistamine effect of promethazine present in this medicine can help to reduce a cough that is caused by post‑nasal drip from allergies or a cold. It helps to dry up the mucus that can tickle the back of your throat and make you cough.
