Less than 1% of amlodipine users will experience the gums in their mouth becoming thicker or more prominent. Sometimes, the gums might even bleed a little. This can look similar to gum disease.
5. Swelling in Lips and Tongue (Angioedema)
This rare reaction can cause your lips and tongue to swell up. In extremely uncommon cases, it can become severe enough to block your airway—definitely an emergency!
6. Strange Skin Lesions (Erythema Multiforme)
Some patients develop round, red skin lesions, especially on the shins. These are very rare but will need medical attention if they occur.

7. Nausea and Abdominal Pain
About 3% of people feel queasy, and 1–2% might feel diffuse stomach pain—not tied to any one area. These symptoms are generally mild but can catch you off guard if you’re not expecting them.
8. Constipation or Diarrhea
Unusual changes in your bowel habits—either getting backed up or having more frequent trips to the bathroom—are reported in less than 1% of cases. Sometimes, people might even flip-flop between both.
9. Appetite and Weight Changes
Strangely, both weight loss (often due to reduced appetite) and weight gain have been reported. These are rare, but if you’re noticing unexplained shifts in your weight that seem tied to starting the medication, let your healthcare provider know.
10. Difficult Swallowing and Gas
A few unfortunate souls have reported trouble swallowing or feeling unusually gassy and bloated.
11. Pancreatitis or Liver Troubles
Very rare cases of pancreas inflammation or liver issues have cropped up in some people taking amlodipine. These are exceedingly rare, but if you notice ongoing pain in your upper abdomen, yellowing skin or eyes, or changes in your urine or stool color, see a doctor promptly.
12. Fluid in the Lungs (Pulmonary Edema)
This comes with shortness of breath, crackling sounds when your doctor listens to your lungs, and labored breathing. If you’re already at risk for heart or lung troubles, pay extra attention to symptoms like these.
13. Heart Rhythm Disturbances (Arrhythmias)
While mild irregular beats or palpitations are not rare, amlodipine can rarely trigger more serious issues like atrial fibrillation, too-slow (bradycardia) or too-fast (tachycardia) heart rates, or even worsen heart failure in those who already have it. If you feel your heart skipping, racing, or beating weirdly, talk to your healthcare team.
14. Feeling Dizzy or Lightheaded
Low blood pressure can lead to episodes of dizziness or even fainting—especially when standing up quickly. This is more likely if you’re on higher doses, or when combined with certain antibiotics. Always take your time getting up from sitting or lying down!
