Telmisartan / amlodipine is a combination medication containing an angiotensin II receptor blocker (telmisartan) and a calcium channel blocker (amlodipine). It's used to treat adults with high blood pressure. The typical dosage is to take one tablet by mouth once a day. Common side effects include swelling and dizziness. Although the brand Twynsta has been discontinued, the generic medication is still available.
High blood pressure
Telmisartan / amlodipine is a combination of two medications that work together to lower blood pressure.
Telmisartan is an angiotensin II receptor blocker (ARB). It stops the hormone angiotensin II from tightening blood vessels. This allows the blood vessels to relax, which lowers your blood pressure.
Amlodipine is a calcium channel blocker (CCB) that lowers blood pressure by relaxing your blood vessels.

Take telmisartan / amlodipine with or without food at any time of day. If it hurts your stomach, try taking it with food to help.
Take telmisartan / amlodipine exactly as prescribed. Don't change your dose or suddenly stop taking the medication without talking to your provider first. Doing so can cause your blood pressure to rise quickly.
To help see how well telmisartan / amlodipine is working for you, Check your blood pressure regularly at home. Record your readings and bring your log to your medical appointments. Based on your results, your provider might recommend any dose changes if needed.
If you accidentally forget to take telmisartan / amlodipine, take it as soon as you remember. But if the time you typically take your medication next is soon, then skip the missed dose. Never take two doses at the same time to make up any missed doses.
You might feel dizzy when you first start taking telmisartan / amlodipine and when your dose is raised. It should lessen over time as you continue taking the medication and as your body gets used to your new blood pressure.
Stand up slowly or hold onto something when moving from sitting or lying down to prevent a sudden drop in blood pressure. If you feel dizzy or lightheaded while taking telmisartan / amlodipine, contact your provider, as your dose might need adjusting.
Swelling in your feet, ankles, legs, or hands can happen when taking telmisartan / amlodipine. Talk with your provider if you notice swelling. They might recommend tips to ease the swelling, such as sitting or lying down with your legs raised or wearing compression socks.
Eat a healthy diet, including a low-salt diet, while taking telmisartan / amlodipine to help lower your blood pressure.
Try to limit foods high in potassium and potassium-containing salt substitutes. Eating them with telmisartan / amlodipine might raise your potassium levels too much, which can lead to nausea, vomiting, or muscle weakness.
Telmisartan / amlodipine can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Telmisartan / amlodipine shouldn't be taken during pregnancy because it can cause severe, and sometimes life-threatening harm, to unborn babies. Tell your provider before starting treatment if you're pregnant or thinking of becoming pregnant. They'll discuss with you about safer options to lower your blood pressure. If you find out that you're pregnant while taking telmisartan / amlodipine, stop the medication and let your provider know right away.
Risk factors: Not enough fluid in your body | Having diarrhea or vomiting for a long time | Low salt levels in your body | Taking high doses of diuretic medications | History of narrow heart valves (aortic stenosis)
Telmisartan / amlodipine can cause your blood pressure to drop too much, which can make you feel dizzy, tired, or lightheaded. This side effect is more common when you first start telmisartan / amlodipine or when the dose is raised. Make sure to stay well hydrated to avoid having blood pressure that's too low. If your blood pressure drops too much and you feel dizzy, sit down slowly while holding onto something and let your provider know. If you fall and hit your head, get medical help right away.
Risk factors: Taking other medications that can raise potassium levels | Heart failure | Kidney problems
Telmisartan / amlodipine can cause high potassium levels in the blood, even in people with healthy kidneys. Your risk is higher if you take other medications that can raise potassium, such as spironolactone (Aldactone). While taking telmisartan / amlodipine, your provider will order blood tests to check your potassium on a regular basis. If you experience signs of high potassium levels, such as nausea, muscle weakness, or irregular heartbeat, tell your healthcare provider right away. If left untreated, high potassium levels can be dangerous.
Risk factors: Severe coronary artery disease
It's possible for some people to experience worsening chest pain or develop a heart attack while taking telmisartan / amlodipine. The risk is higher when you first start this medication or when your dose is raised. Your risk is also higher if you have severe coronary artery disease (CAD). Get medical help right away if you experience chest pain, pressure in the chest, heartburn, dizziness, or trouble breathing.
Risk factors: Heart failure | Certain kidney problems | Taking other medications that can cause kidney damage
Sometimes, telmisartan / amlodipine can affect your kidneys and cause them to not work as well. The risk is higher for people who have certain types of kidney problems, such as renal artery stenosis or severe heart failure. Your provider might order lab tests every so often to make sure your kidneys are healthy and working properly. If you develop kidney problems, or if your kidney problems worsen while taking telmisartan / amlodipine, your provider might recommend that you stop taking this medication. Let your provider know if you're urinating less often than usual, as this could be a sign that your kidneys aren't working as well.
