Xalatan and blood test results
Routine blood tests sometimes shift in unexpected ways during treatment with a chronic medication. Xalatan (Latanoprost) at 0.005% may directly alter certain lab parameters, indirectly affect others through its mechanism, or interfere with the assay itself in rare cases. Knowing what is normal, what is monitored and what is artefact prevents unnecessary worry.
Lab effects of Xalatan
Possible lab effects of Latanoprost are listed in the prescribing information. They typically reflect the medication's mechanism: changes in liver enzymes, kidney function markers, blood counts, electrolytes, glucose or lipids depending on the agent. Latanoprost is a prodrug ester hydrolysed by corneal esterases to its active free acid, which selectively binds the prostaglandin F (FP) receptor. Most changes are mild and reversible; significant shifts trigger dose adjustment or further investigation.
Routine monitoring
According to the prescribing information for Latanoprost, baseline labs before starting Xalatan and periodic monitoring during treatment are recommended for many medications in Eye Care and Ophthalmic Treatments. The frequency depends on the agent and on individual risk factors. Fasting requirements for specific tests are independent of Xalatan dosing — the test instructions take precedence.
Frequently asked questions
Can Xalatan change my blood test results? ▾

Should I fast before blood tests on Xalatan? ▾
Fasting requirements depend on the test, not on Xalatan. Continue Xalatan at 0.005% on the usual schedule unless the lab specifically instructs otherwise. The pharmacist confirms whether the medication should be held before particular tests.
