For tamsulosin, pay close attention to the decimal in the capsule strength. The capsule described here contains 0.4 mg. Enter the number of capsules in the quantity field, separate from the strength.
Match your prescription before comparing
Your total prescribed daily amount and the strength of one capsule are not always the same number. Match the capsule itself in the search and use the quantity the pharmacy will dispense. Do not calculate a new dose from a price example.

Search example, not a dose recommendation
Tamsulosin 0.4 mg · 30 capsules
Choose the matching product from the search suggestions, enter the actual quantity and days supply on your prescription and your pharmacy ZIP code, then compare the results. Update the example details to match your own prescription.
How can I avoid comparing different capsule quantities?
Check the quantity on every result before comparing totals. If your prescription calls for 60 capsules, a quote for 30 capsules is not the cost of that fill. Enter 60 in the search and verify the pharmacy address and attached savings card again.
Two pricing options. Use the card linked to your price.
RxNow checks its available pricing connections for BIN 019330 and BIN 610272. The search displays the lower returned price for each matched pharmacy when both options are available. One network can cost less for one prescription and more for another.
Select the card attached to your chosen pharmacy result. Its BIN, PCN and Group must stay together. The pharmacy confirms the final price when it processes the prescription. Search results are estimates, not a guarantee of price, stock or acceptance.
Free to use. No patient enrollment. No mail order. RxNow does not ask for your name or date of birth to search prices or download a card. A valid prescription is required; your pharmacy handles its normal patient information.
RxNow is a prescription discount program, not insurance. Ask the pharmacy to compare the RxNow price with your insurance copay or other available price; they cannot be combined on the same prescription purchase.
