Novahistine Dh is a combination medication that contains two active ingredients: pseudoephedrine and chlorpheniramine. Pseudoephedrine is a decongestant that works by narrowing the blood vessels in the nasal passages, which helps to reduce congestion and improve breathing. Chlorpheniramine is an antihistamine that helps to relieve symptoms such as sneezing, itching, and watery eyes by blocking the action of histamine, a substance in the body that causes allergic symptoms.

Novahistine Dh is commonly used to treat symptoms of the common cold, allergies, and sinus congestion. It can help to alleviate nasal congestion, runny nose, sneezing, and itchy or watery eyes. This medication is available in tablet form and should be taken as directed by a healthcare provider.

As with any medication, Novahistine Dh may cause side effects in some individuals. Common side effects may include drowsiness, dizziness, dry mouth, and blurred vision. It is important to avoid driving or operating heavy machinery while taking this medication until you know how it affects you. If you experience any severe or persistent side effects, it is important to contact your healthcare provider.

It is important to inform your healthcare provider of any other medications or supplements you are taking before starting Novahistine Dh, as it may interact with certain medications. Additionally, this medication may not be suitable for individuals with certain medical conditions, such as high blood pressure, heart disease, or thyroid problems.

Overall, Novahistine Dh can be an effective treatment for relieving symptoms of nasal congestion and allergies when used as directed. If you have any questions or concerns about this medication, do not hesitate to speak with your healthcare provider.
