  • Increased ALT/AST
  • Rhabdomyolysis
19
Q

Tx of statin-induced myalgia

A
  • Exclude rhabdomyolysis (CK and urine dip - myoglobin)
  • Ensure needs statin
  • Reduce dose
  • Switch to another statin with lower risk
20
Q

Myalgia risk of statins (in order)

A
  1. Simvastatin
  2. Atorvastatin
  3. Pravastatin
  4. Fluvastatin
    or a fibrate
21
Q

Metformin

A
  • Lactic acidosis
22
Q

Alcohol use

A
  • Acute: increases warfarin effect

- Chronic: reduces warfarin effect

23
Q

MAOIs

A
  • Hypertensive crisis
24
Q

Sedation causes

A
  • Barbiturates
  • Opioids
  • Benzos
25
Alcohol: Metronidazole and disulfiram
- Sweating - Flushing - Nausea - Vomiting
26
Tx of rhabdomyolysis
- Stop drug - If renal failure - urgent dialysis - IV fluids - Consider sodium bicarbonate - Monitor serum potassium (hyper from cell breakdown)
27
DOACs
- Bleeding - Anaemia - Nausea
28
Carbimazole
- Rash - Pruiritis - Agranulocytosis (SORE THROAT) - Bone marrow suppression - Jaundice - Acute pancreatitis
29
Methotrexate
- Stomatitis - Stevens-Johnson - Toxic epidermal necrolysis - Blood disorders - Hepatotoxicity - Interstitial pneumonitis
30
Phenytoin
- Gingival hypertrophy - Hirsutism - Tremor - Leucopenia - Steven-Johnsons - Pneumonitis
31
Theophylline
- Hypokalaemia - N+V - Tremor - Palpitations
32
Sodium Valproate
- SIADH - Hyponatraemia - Pancreatitis - Bone marrow failure - Anaemia
33
Drugs that increase GI bleed risk
- Antiplatelets: aspirin, clopidogrel - Anticoagulants: warfarin - Corticosteroids - NSAIDs - SSRIs - Bisphosphonates - Doxycycline
34
Drugs that cause weight gain
- SSRIs - Anti-psychotics: clozapine, lithium, olanzapine, quetiapine, risperidone - Sulphonylureas - Corticosteroids - Amitryptilline - Sodium Valproate - Insulin
35
HRT adverse effects
- HTN, STOP if BP > 160/96 (sodium and fluid retention) - Can cause cholestatic jaundice, but no routine LFTs needed - Serum cholesterol can increase but unlikely if on statin. Regular statin measurements. - Can cause weight gain - Breast cancer
36
HRT monitoring
- BP - Breast status - Statins (not as important)
37
Statins and ALT
Measure liver enzymes at baseline, 3 months and 12 months - Stop if > 3x baseline - Fine if < 3x baseline
