Dosing & Uses

AdultPediatric

Dosage Forms & Strengths

tablet

  • 20mg
  • 40mg
  • 80mg

Hypertension

Indicated for treatment of hypertension

Dosage must be individualized

40 mg/day PO initially; titrated to 20-80 mg/day PO, depending on response; patients with volume depletion should receive the lower dosage initially, under close supervision

Most of the antihypertensive effect is apparent within 2 weeks and maximal reduction is generally attained after 4 weeks

When additional blood pressure reduction is required after the 80-mg dose, a diuretic may be added

Cardiovascular risk reduction

Indicated for cardiovascular (CV) risk reduction in patients unable to take ACE inhibitors

80 mg PO qDay

Unknown whether doses lower than 80 mg are effective in reducing the risk of cardiovascular morbidity and mortality

Dosage Modifications

Renal impairment: No dosage adjustment necessary; hemodialysis (HD) patients at risk for orthostatic hypotension

Hepatic impairment

  • In patients with hepatic insufficiency, plasma concentrations of telmisartan increased, and absolute bioavailability approached 100%
  • Monitor carefully and titrate up slowly in patients with biliary obstructive disorders or hepatic insufficiency

Dosing Considerations

Use of telmisartan with an ACE inhibitor is not recommended

            Warnings

            Black Box Warnings

            Fetal toxicity

            • When pregnancy is detected, discontinue telmisartan as soon as possible
            • Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus

            Contraindications

            Hypersensitivity to telmisartan or any other component of this product

            Coadministration with aliskiren in patients with diabetes

            Cautions

            Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death

            Hyperkalemia may occur in patients on ARBs, particularly in patients with advanced renal impairment, heart failure, on renal replacement therapy, or on potassium supplements, potassium-sparing diuretics, potassium-containing salt substitutes or other drugs that increase potassium level

            As the majority of telmisartan is eliminated by biliary excretion, patients with biliary obstructive disorders or hepatic insufficiency can be expected to have reduce clearance

            Pregnancy (2nd and 3rd trimesters); significant risk of fetal or neonatal morbidity and mortality (see Black Box Warnings)

            Dual blockade of the renin-angiotensin system with angiotensin-receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors, or aliskiren is associated with increased risk of hypotension, hyperkalemia, and altered renal function (including acute renal failure) in comparison with monotherapy

            Most patients receiving the combination of two RAS inhibitors do not obtain any additional benefit compared to monotherapy; avoid combined use of RAS inhibitors; closely monitor blood pressure, renal function and electrolytes in patients on benazepril and other agents that affect the RAS

            Drug interaction overview

            • Not for coadministration with aliskiren in patients with diabetes; avoid use of aliskiren with telmisartan in patients with renal impairment (GFR <60 ml/min/1.73 m2)
            • When coadministered with digoxin, median increases in digoxin peak plasma concentration (49%) and in trough concentration (20%) were observed; monitor digoxin levels when initiating, adjusting, and discontinuing telmisartan

            Pregnancy & Lactation

            Pregnancy

            May cause fetal harm when administered to a pregnant woman

            Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death

            Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents

            When pregnancy is detected, discontinue as soon as possible

            Animal data

            • Studies in rats and rabbits with telmisartan showed fetotoxicity only at maternally toxic doses

            Clinical considerations

            • Disease-associated maternal and/or embryo/fetal risk
              • Hypertension in pregnancy increases the maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (eg, need for cesarean section, postpartum hemorrhage)
              • Hypertension increases the fetal risk for intrauterine growth restriction and intrauterine death
              • Carefully monitor pregnant women with hypertension and managed accordingly
            • Fetal/neonatal adverse reactions
              • Use of drugs that act on the RAS in the second and third trimesters of pregnancy can result in the following: oligohydramnios, reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations, including skull hypoplasia, hypotension, and death
              • During pregnancy, perform serial ultrasound examinations to assess the intra-amniotic environment
              • Fetal testing may be appropriate, based on the week of gestation
              • If oligohydramnios is observed, discontinue telmisartan, unless it is considered lifesaving for the mother
              • Note: Oligohydramnios may not appear until after the fetus has sustained irreversible injury
              • Closely observe infants with histories of in utero exposure to telmisartan for hypotension, oliguria, and hyperkalemia
              • If oliguria or hypotension occurs, support blood pressure and renal perfusion
              • May require transfusions or dialysis as a means of reversing hypotension and/or substituting for disordered renal function

            Lactation

            There is no information regarding the presence of telmisartan in human milk, the effects on the breastfed infant, or the effects on milk production

            Present in the milk of lactating rats

            Advise a nursing woman not to breastfeed during treatment

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

If you are planning pregnancy, become pregnant, or think you may be pregnant, tell your doctor right away.

            USES: This medication is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Telmisartan belongs to a class of drugs called angiotensin receptor blockers (ARBs). It works by relaxing blood vessels so blood can flow more easily.

            HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking telmisartan and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth with or without food as directed by your doctor, usually once daily.The dosage is based on your medical condition and response to treatment.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick. For the treatment of high blood pressure, it may take up to 4 weeks before you get the full benefit of this drug.Tell your doctor if your condition does not improve or if it worsens (such as your blood pressure readings remain high or increase).

            SIDE EFFECTS: Dizziness or lightheadedness may occur as your body adjusts to the medication. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly.To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: fainting, symptoms of a high potassium blood level (such as muscle weakness, slow/irregular heartbeat).Although telmisartan may be used to prevent kidney problems or treat people who have kidney problems, it may also rarely cause serious kidney problems or make them worse. Your doctor will check your kidney function while you are taking telmisartan. Tell your doctor right away if you have any signs of kidney problems such as a change in the amount of urine.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects.
