People taking amlodipine for high blood pressure or angina have been urged to seek advice if they notice their gums becoming unusually puffy or enlarged. Pharmacist Raj Patel, who shares advice with more than 100,000 TikTok followers as the Straight-Talking Pharmacist, has highlighted a possible side effect that can be mistaken for a dental problem.
What Is Gingival Hyperplasia?
In his recent video, Patel said: "It surprises me how few people know a blood pressure tablet can sometimes affect their gums." The reaction is known as gingival hyperplasia, which describes an overgrowth of gum tissue that can make the gums appear thicker or extend further over the teeth.
The UK prescribing information for amlodipine lists gingival hyperplasia as a very rare adverse effect, estimated to affect fewer than one in 10,000 people. The medicine is more commonly associated with side effects such as ankle swelling, headache, flushing and dizziness.
When to See a Dentist
Patel added: "Most people know amlodipine can cause ankle swelling, headache, flushing or dizziness. Far fewer know about this one."
However, gum swelling can have several causes, and the NHS says gum disease is very common, with symptoms including red, sore or bleeding gums. It recommends seeing a dentist if gums bleed when brushing or become painful and swollen.
What to Do If You Notice Changes
Patel cautioned against assuming that a prescription is to blame, saying: "Swollen or bleeding gums are much more commonly caused by gum disease or another dental problem than by amlodipine." Anyone noticing a change should arrange a dental check and tell the dentist about their medication, particularly if the gums appear to be growing over the teeth or the problem is getting worse.
A dentist can examine the gums and assess whether gum disease or another oral health issue could explain the symptoms. If a medicine-related reaction is suspected, patients can ask their pharmacist or prescriber to review their treatment and discuss the options.
Regular brushing with fluoride toothpaste and cleaning between the teeth can help control plaque, which contributes to gum disease. But patients should not stop taking amlodipine on their own, as doing so can allow the condition being treated to become uncontrolled.
Patel's advice is to seek professional guidance rather than make medication changes independently. A review does not automatically mean the prescription must change, but it can help establish whether the gum problem may be linked to the medicine and what should happen next.
