Here is a thorough overview of medicines used for cough and cold:
Medicines for Cough and Cold
The common cold is a viral upper respiratory infection - antibiotics are not effective and should not be used. Treatment is aimed at relieving individual symptoms.
1. Cough Suppressants (Antitussives)
These reduce the urge to cough. Best for a dry, non-productive cough.
| Drug | Examples | Notes |
|---|---|---|
| Dextromethorphan | Delsym, Robitussin DM | Most common OTC option; safe in adults |
| Codeine | Prescription syrups | Discouraged as a first choice; risk of dependence |
| Benzonatate | Tessalon (Rx only) | Numbs the stretch receptors in the lungs |
Per Fishman's Pulmonary Diseases: "In previously healthy children and adults, there is no danger from the routine use of cough suppressants, although they should be used cautiously in patients with serious underlying COPD."
2. Expectorants
These thin and loosen mucus, making it easier to cough up. Best for a productive (wet) cough.
| Drug | Examples | Notes |
|---|---|---|
| Guaifenesin | Mucinex, Robitussin | May reduce cough reflex; drink plenty of water with it |
Note: The efficacy of expectorants is "not proved" definitively, but guaifenesin is widely used and generally safe - Berek & Novak's Gynecology.
3. Decongestants
These relieve nasal stuffiness by constricting blood vessels in the nasal passages.
| Drug | Examples | Notes |
|---|---|---|
| Pseudoephedrine | Sudafed | Oral; proven to improve nasal airflow; kept behind pharmacy counter |
| Phenylephrine | Sudafed PE | Oral form has limited evidence of effectiveness |
| Oxymetazoline / Xylometazoline | Afrin, Otrivin | Nasal spray; fast-acting but do not use >3 days (causes rebound congestion) |
Caution: Phenylpropanolamine has been removed from OTC cold remedies due to an increased risk of hemorrhagic stroke.
4. Antihistamines
Help with runny nose and sneezing. Older (sedating) antihistamines work better for cold symptoms than newer non-sedating ones, because they also have anticholinergic (drying) effects.
| Drug | Type | Examples |
|---|---|---|
| Chlorpheniramine | 1st gen (sedating) | Chlor-Trimeton |
| Diphenhydramine | 1st gen (sedating) | Benadryl |
| Cetirizine / Loratadine | 2nd gen (non-sedating) | Zyrtec, Claritin - less effective for cold |
Histamine does NOT appear to play a major role in cold symptoms, which is why selective H1 antihistamines (newer ones) are less effective - Fishman's Pulmonary Diseases.
5. Pain Relievers / Fever Reducers (Analgesics)
For sore throat, headache, body aches, and fever.
| Drug | Examples | Notes |
|---|---|---|
| Paracetamol (Acetaminophen) | Tylenol, Crocin | Safest option; suitable for all ages |
| Ibuprofen | Advil, Brufen | Also reduces inflammation; avoid on empty stomach |
| Aspirin | Avoid in children under 16 (risk of Reye's syndrome) |
6. Zinc Lozenges
- Zinc has some evidence for shortening the duration of a cold if started within 24 hours of symptom onset.
- Effective in adults; not recommended in young children.
Special Considerations
Children Under 4 Years
- OTC cough and cold medicines (decongestants, antihistamines) are NOT recommended - no proven benefit and risk of serious side effects including seizures and CNS toxicity.
- Use saline nasal drops, a humidifier, and honey (for children >1 year) for cough relief.
Pregnancy
- Avoid most decongestants, especially in the first trimester.
- Paracetamol is the safest pain/fever option.
Common Combination Products
Many OTC products combine multiple agents:
| Product Type | What's Inside |
|---|---|
| Day cold & flu | Decongestant + paracetamol + sometimes guaifenesin |
| Night cold & flu | Antihistamine + decongestant + paracetamol |
| Cough syrup (dry cough) | Dextromethorphan |
| Cough syrup (wet cough) | Guaifenesin |
What Actually Works (Evidence Summary)
| Treatment | Adults | Children |
|---|---|---|
| Analgesics (paracetamol, ibuprofen) | Yes | Yes (avoid aspirin) |
| Pseudoephedrine (decongestant) | Yes | Caution |
| Sedating antihistamines | Short-term benefit | Not under 4 yrs |
| Dextromethorphan (cough suppressant) | Yes | Not under 4 yrs |
| Zinc lozenges | Yes (if early) | Limited evidence |
| Antibiotics | No | No |

Irregular Menstrual Cycles in a 19-Year-Old Female
First: Rule Out Causes Before Prescribing
A 19-year-old with irregular cycles needs a proper workup before starting any medicine. The treatment depends entirely on the cause. Key causes to rule out:
| Cause | Investigation |
|---|---|
| Pregnancy | Urine/serum β-hCG (must rule out first) |
| PCOS (most common in this age) | Ultrasound pelvis, LH/FSH ratio, testosterone |
| Hypothyroidism | TSH, T3, T4 (thyroid dysfunction interferes with sex hormone metabolism and causes irregular cycles) |
| Hyperprolactinemia | Serum prolactin |
| Stress / low body weight / excessive exercise | Clinical history |
| Anovulation (common within 1-3 years of first period) | Clinical assessment |
| Coagulation disorder | CBC, coagulation screen (especially if heavy bleeding) |
In young women who develop irregular bleeding due to anovulation within the first years after menarche and in whom there are no signs of other conditions, the prognosis for regular ovulatory cycles is good - Berek & Novak's Gynecology.
Treatment Options Based on Diagnosis
1. Simple Anovulatory Cycles (Commonest in Teenagers)
No serious disease found - cycles are just immature. Options:
Option A: Cyclic Progestin (to regulate withdrawal bleed)
- Medroxyprogesterone acetate (Provera) 10 mg once daily
- Give on days 16-25 of each month (10 days per cycle)
- This triggers a withdrawal bleed and simulates a "period"
- Does NOT suppress ovulation; just regulates bleeding pattern
Option B: Norethindrone (Primolut N) 5 mg
- Days 16-25 of cycle, once daily
- Same principle - induces regular withdrawal bleeding
Subsequent hormonal therapy with combined oral contraceptives, levonorgestrel IUS, or progestin therapy are all useful following initial control of irregular bleeding - Berek & Novak's Gynecology.
2. If PCOS is Confirmed (Most Common Cause in this Age Group)
First-line: Combined Oral Contraceptive Pill (COCP)
- Any low-dose pill with ethinyl estradiol 20-35 mcg + progestin
- Examples: Yasmin (EE + drospirenone), Diane-35 (EE + cyproterone - especially good if acne/hirsutism present), Loette, Novelon
- Take 1 tablet daily for 21 days, then 7-day break (withdrawal bleed occurs in break), then repeat
- This gives regular, predictable cycles every month
Second-line: Metformin 500-1500 mg/day (if insulin resistance is present)
- Helps restore ovulation in PCOS over 3-6 months
- Often combined with OCP
3. If Thyroid Disorder is Found
- Treat the underlying thyroid condition (levothyroxine for hypothyroidism)
- Cycles usually regularize once thyroid function normalizes
Summary Table: When to Give What
| Situation | Medicine | When to Give |
|---|---|---|
| Anovulatory cycles, no contraception needed | Medroxyprogesterone 10 mg or Norethindrone 5 mg | Days 16-25 of each cycle |
| PCOS, wants cycle regulation | Combined OCP (EE 20-35 mcg) | Day 1 of cycle, 1 tab daily x 21 days, then 7-day break |
| PCOS with insulin resistance | Metformin 500 mg BD-TDS | Daily with meals (long-term) |
| Heavy acute bleeding episode | OCP taper: 1 tab twice daily x 5 days, then 1 tab daily | Start immediately to control bleeding |
| Hypothyroidism causing irregularity | Levothyroxine (per TSH levels) | Daily on empty stomach |
Important Notes
- Always rule out pregnancy first before giving any hormonal therapy
- COCP is contraindicated in: history of blood clots, stroke, active liver disease, severe hypertension, migraines with aura
- Irregular cycles in adolescents within 2-3 years of first period (menarche) can be physiologically normal - the hypothalamic-pituitary-ovarian axis is still maturing
- If no period for >90 days (amenorrhea), more thorough evaluation is needed
- Lifestyle advice is important: manage stress, maintain healthy weight, regular exercise (but not excessive)
