Ibuprofen is available for purchase in most countries, and this is the recommended medication to use for the pain and cramping. You can use 3-4 (200mg) ibuprofen tablets every 6-8 hours for pain.
Tylenol can also be used, 2 (325 mg tablets) of tylenol every 4-6 hours for pain. Heating pads or massaging the lower stomach (uterus) may also be helpful for the pain.
