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.
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.
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.

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.

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.
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.
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.
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
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.
