Dysmenorrhea

exp date isn't null, but text field is

It is a painful menstruation preventing normal activities and requires medication. There are 2 types  of dysmenorrhea: 

Primary (no organic cause). Typically, pain occurs on the first day of menses, usually about the  time the flow begins. 

Secondary (pathological cause) e.g., usually the pain is due to other underlying causes eg PID,  endometriosis, etc. 

Pharmacological Treatment 

A: ibuprofen (PO) 200–600mg 8hourly (maximum 2.4 g/day) 

OR 

A: acetylsalicylic acid (PO) 300–600mg 4hourly 

OR 

A: diclofenac (PO) 50–100mg 8–12hourly 
OR 

B: mefenamic acid (PO) 500mg 8hourly 

AND 

A: hyoscine butyl bromide (PO) 20mg 8hourly for 5days 

Women with regular complaints can easily detect length of use during their periods (2–3days usually  enough). Treat the underlying condition if known 

Note: For primary dysmenorrhea patients may be advised to start taking ibuprofen one or two days 

before menses and continue for three to four days during menses to minimize painful menstruation
