pharmacist-tips

Pharmacist tips for Telmisartan / amlodipine

pharmacist
  • 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.

                • 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.

                  faqs

                  Frequently asked questions about Telmisartan / amlodipine

                  Can you take amlodipine and telmisartan together?
                  Yes, it's safe to take amlodipine and telmisartan together because they work differently from each other to lower blood pressure. Also, both medications are first-choice treatment options for high blood pressure. Depending on how high your blood pressure is and your risk for other problems caused by high blood pressure (e.g., heart attack or stroke), your provider might recommend that you take a combination blood pressure medication like telmisartan / amlodipine.
                  Is telmisartan / amlodipine a blood thinner?
                  No, telmisartan / amlodipine isn't a blood thinner and doesn't raise your risk for bleeding. It's a combination medication that works to lower your blood pressure by relaxing your blood vessels.
                  What is the best time to take telmisartan / amlodipine?
                  In general, it's not completely clear when the best time of day to take blood pressure medications like telmisartan / amlodipine is. While studies are mixed, the most important thing is to take telmisartan / amlodipine consistently at the same time every day so it can work as best as possible.
                  Can telmisartan / amlodipine be cut in half?
                  The manufacturer of telmisartan / amlodipine doesn't specify if the tablets can be cut in half or not. The tablets aren't made with a special coating around them, which means it might be safe to cut them. But, the tablets also aren't scored (an indented line in the middle of the tablet), so cutting them in half might be difficult. If you're having trouble swallowing the tablets, talk to your provider
                  How long does it take for telmisartan / amlodipine to start working?
                  It typically takes about 2 weeks for telmisartan / amlodipine to lower your blood pressure. If needed, your provider can raise your dose as long as you're not having side effects from the medication. Keep in mind that it can take some time before you reach a dose that controls your blood pressure. So make sure to be patient, continue taking telmisartan / amlodipine, and follow up with your provider regularly.
                  Is there a generic for telmisartan / amlodipine?
                  Yes, telmisartan / amlodipine is only available as a lower-cost generic. The brand, Twynsta, was discontinued by the manufacturer and is no longer available.

                  What are the risks and warnings for Telmisartan / amlodipine?

                  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.

                  risk-warning

                  Harm to unborn baby

                  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-warning

                  Low blood pressure

                  • 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-warning

                    High potassium levels

                    • 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-warning

                      Risk of heart attack or chest pain

                      • 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-warning

                        Possible kidney damage in certain people

                        • 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.
