Buying from a pharmacy outside the U.S.? Read Is it safe to order Tykerb from Canada?
90-day cost = 450 tablets at the usual dose of 5 a day, bought as one order of whole packs with one shipping fee. 90-day cost is worked out from each pharmacy's real order size so different pack sizes compare fairly. Orders are kept within a 3-month supply (92 days); a pack that is larger than that is marked and not used for the lowest price at the top of this page. Prices checked Nov 11, 2026 on each pharmacy's website, in U.S. dollars. Savings compare with the U.S. list price. The lowest price at the top of this page uses only packs whose maker the pharmacy names, or whose product country and ships-from country it states. Price is the pharmacy's own price for one pack, as shown on its website (converted to U.S. dollars when it prices in Canadian dollars). Delivery is the pharmacy's own estimate for the shipping option shown, not a promise; some pharmacies count from when they receive your prescription or ship the order. Total = the packs needed + shipping. When those packs don't add up to exactly 90 days, the row shows what that order costs and, under it, what it works out to for 90 days; we sort by the 90-day amount so pack sizes compare fairly. Prices change often; confirm at checkout. “Fee not published” means the pharmacy doesn’t show its shipping fee before checkout, so that row’s total is the medicine price only.

Tykerb coupons and savings programs
We show the programs that usually fit, cheapest first where we know the price. Private insurance means a plan through work or one you buy yourself. Programs set their own rules, so check the terms before you count on one. We don't save this choice.

- Medicare Extra Help: if you have Medicare and limited income, Extra Help lowers what you pay for prescriptions. (Social Security)
- Medicare Prescription Payment Plan: a free Medicare option that spreads your drug costs into monthly payments across the year. It doesn't lower the total, but it can make costs easier to manage. (Medicare.gov)

What is Tykerb used for?
Tykerb (lapatinib) is a kinase inhibitor, a kind of targeted cancer medicine. According to its FDA label (DailyMed), it is used together with other medicines to treat:
- Advanced or metastatic HER2-positive breast cancer, with capecitabine, in people who already had treatment that included an anthracycline, a taxane and trastuzumab.
- Hormone receptor-positive, HER2-positive metastatic breast cancer, with letrozole, in women after menopause for whom hormone therapy is right.
Tykerb comes as 250 mg tablets in bottles of 150. The dose is 1,250 mg (5 tablets) once a day with capecitabine, or 1,500 mg (6 tablets) once a day with letrozole, taken at least 1 hour before or after a meal. Boxed warning: Tykerb can cause liver damage, which may be severe, and deaths have been reported. Your prescriber decides which medicine is right for you.
Is it safe to order Tykerb from Canada?
Many Americans do, but U.S. law and customs rules apply, and for Tykerb, compare the U.S. price of FDA-approved generic lapatinib before you order. Federal law generally doesn't allow individuals to import prescription drugs, though under its personal importation policy the FDA has long used enforcement discretion for some personal-use shipments, generally no more than a three-month supply (FDA). Congress has said enforcement against individuals should focus on imports that pose a significant threat to public health (Federal Food, Drug, and Cosmetic Act section 804(j)(1), 21 U.S.C. 384(j)(1)). You need a prescription from your doctor. New U.S. Customs rules for mailed orders start January 20, 2027. In Canada, Tykerb 250 mg tablets are sold under the same name by Novartis and listed as marketed (Health Canada).
