Dyna Dynaprim Suspension 100ml

Dyna Dynaprim Suspension is a combination antibacterial medication containing trimethoprim and sulfamethoxazole (co-trimoxazole) as its active ingredients. It is used to treat various bacterial infections, including certain urinary tract and respiratory infections. The two ingredients work together by blocking different stages of bacterial folic acid production, helping to stop bacterial growth. If you're using this medicine for the first time, you're probably wondering how it fits into treatment — it is usually taken twice daily and can be given with or without food. Some people experience nausea, vomiting, reduced appetite, or skin rash. Completing the full prescribed course is important, even if symptoms improve early, as stopping too soon may allow the infection to return. Since this medication contains a sulphonamide component that may cause allergic reactions or rare serious skin reactions, discuss any history of sulpha allergy, kidney problems, liver disease, or blood disorders with your doctor before use.

The dosage is based on the patient's age, weight, and the type of infection being treated. In children, dosing is generally calculated according to body weight, commonly equivalent to around 6mg trimethoprim and 30mg sulfamethoxazole per kg per day, divided into two doses. Treatment is usually continued for at least 5 days and until symptoms have improved for a few days, according to your doctor's advice.
