What Is Twynsta? Uses, Dosage, and What You Need to Know in 2026

Twynsta is a prescription blood pressure medication that combines two active ingredients into a single daily tablet. If you've been prescribed it — or you're researching it for a family member — here's a complete, plain-English overview of what it is, how it works, and how to take it.

What Is Twynsta?

Twynsta is the brand name for a fixed-dose combination tablet containing:

Telmisartan — an angiotensin II receptor blocker (ARB)

Amlodipine — a dihydropyridine calcium channel blocker (CCB)

Twynsta was originally FDA-approved on October 16, 2009, and manufactured by Boehringer Ingelheim Pharmaceuticals. The brand name has since been discontinued, but the generic version (telmisartan/amlodipine) is still available.

What Is Twynsta Used For?

Twynsta is FDA-approved for the treatment of hypertension (high blood pressure) in adults. It is used:

As initial therapy in patients with moderate-to-severe hypertension who are likely to need more than one drug

As add-on therapy for patients not adequately controlled on amlodipine alone or telmisartan alone

As a convenient single-tablet option for patients already taking amlodipine and telmisartan as separate pills

Lowering blood pressure with Twynsta reduces the risk of fatal and nonfatal cardiovascular events — primarily strokes and heart attacks.

Twynsta Dosage Forms and Strengths

Twynsta comes as a once-daily oral tablet in four strengths (telmisartan/amlodipine):

40/5 mg (40 mg telmisartan + 5 mg amlodipine)

40/10 mg (40 mg telmisartan + 10 mg amlodipine)

80/5 mg (80 mg telmisartan + 5 mg amlodipine) — most commonly prescribed starting strength

80/10 mg (80 mg telmisartan + 10 mg amlodipine) — maximum recommended dose

How to Take Twynsta

Once daily: Take one tablet at the same time each day

With or without food: No food requirements, but avoid grapefruit juice (it may increase amlodipine absorption)

Protect from moisture: Keep tablets in the original blister pack until just before taking — the tablets are hygroscopic (absorb moisture easily)

Storage: Store at room temperature (77°F/25°C), protected from light and moisture

When Does Twynsta Start Working?

Most patients see a significant blood pressure reduction within 2 weeks of starting Twynsta. Full antihypertensive effects are generally achieved by 4 weeks. Your doctor may adjust your dose if blood pressure goals aren't met after 2 weeks.

Who Should Not Take Twynsta?

Pregnant women (especially 2nd and 3rd trimester — can cause fetal injury or death)

Patients with known allergy to telmisartan, amlodipine, or any dihydropyridine drug

Patients with diabetes taking aliskiren (Tekturna) — contraindicated combination

Patients with severe liver disease

Children under 18 (safety not established)

Is Twynsta a Controlled Substance?

No. Twynsta is not a controlled substance. It has no abuse potential and is not scheduled by the DEA. You can receive a 90-day supply, refills by phone, and prescriptions by mail — making it more flexible than controlled substances like certain pain medications or stimulants.

Is Twynsta Still Available in 2026?

Brand-name Twynsta was discontinued by Boehringer Ingelheim and is no longer sold. The generic (telmisartan/amlodipine) remains available from a limited number of manufacturers but can be difficult to find at many pharmacies. For a full explanation, see our guide on why Twynsta is hard to find in 2026. Many patients have also successfully transitioned to taking the two components separately — generic amlodipine and generic telmisartan — which are widely available and significantly less expensive.
